Abstract: Diagnostic ultrasound provides a technique whereby real-time, in vivo analysis of peripheral nerve movement is possible. This study measured sciatic nerve movement during a "slider" neural mobilisation technique (ankle dorsiflexion lantar flexion and cervical extension/flexion). Transverse and longitudinal movement was assessed from still ultrasound images and video sequences by using frame-by-frame cross-correlation software. Sciatic nerve movement was recorded in the transverse and longitudinal planes. For transverse movement, at the posterior midthigh (PMT) the mean value of lateral sciatic nerve movement was 3.54 mm (standard error of measurement [SEM] +/- 1.18 mm) compared with anterior-posterior/vertical (AP) movement of 1.61 mm (SEM +/- 0.78 mm). At the popliteal crease (PC) scanning location, lateral movement was 6.62 mm (SEM +/- 1.10 mm) compared with AP movement of 3.26 mm (SEM +/- 0.99 mm). Mean longitudinal sciatic nerve movement at the PMT was 3.47 mm (SEM +/- 0.79 mm n = 27) compared with the PC of 5.22 mm (SEM +/- 0.05 mm n = 3). The reliability of ultrasound measurement of transverse sciatic nerve movement was fair to excellent (Intraclass correlation coefficient [ICC] = 0.39-0.76) compared with excellent (ICC = 0.75) for analysis of longitudinal movement. Diagnostic ultrasound presents a reliable, noninvasive, real-time, in vivo method for analysis of sciatic nerve movement.

Abstract: This paper presents a 3D finite element upper arm model, validated by experiments as well as clinical data, used to study the error introduced in blood pressure measurements due to variability of arm tissue mechanical properties. The model consists of three separate cylindrical parts: soft tissue, bone and brachial artery. The artery volume changes under the cuff are used to represent the cuff pressure oscillations for analyzing blood pressure measurements. These oscillation trends are identical to observed clinical data. Also an upper arm simulator is designed and built for model validation. The model shows that the variation of soft tissue compressibility introduces an error up to 5% in blood pressure measurements. It is also revealed that the variation of the brachial artery and arm tissue stiffness has an insignificant effect on oscillometric blood pressure measurement method.

Abstract: A cross-sectional reliability study was conducted with 23 normal participants to establish normal values, and the repeatability and validity of distal radioulnar joint translation measurements using ultrasound imaging. Static transverse images of maximal supination, neutral and maximal pronation were examined to assess translation, using a method consistent with the rheumatoid arthritis subluxation ratio. Translation while gripping a 1 kg weight in supinated and pronated positions was then compared with non-gripping translation. There was significantly more ulnar radial translation found with pronation than supination, when compared with neutral. Gripping in pronation did not produce statistically significant changes in translation, whereas the changes produced by gripping in supination were significant. Internal consistency was deemed very high and the rheumatoid arthritis subluxation ratio values measured using ultrasound imaging were consistent with previously documented values measured by computerized tomography. This study demonstrated that translational movement of the distal radioulnar joint can be reliably detected in healthy participants using ultrasound imaging. This may reduce dependency on other imaging modalities to diagnose distal radioulnar joint instability. Level of Evidence: 2.

Abstract: Axial rotation of the trunk is important to many vocational tasks and activities of daily living, and may be associated with back injuries. The influence of spinal postures on trunk rotation appears conflicting. This study investigated the influence of forward trunk inclination, spinal posture and pelvic fixation on maximum trunk rotation. Twenty male participants were assessed using an optoelectronic motion-analysis system to track trunk movement during maximal trunk rotations in different spinal positions within the sagittal plane. A repeated-measures multivariate analysis of variance investigated the effects of forward trunk inclination, spinal posture and pelvic fixation on trunk and pelvic rotation. Test-retest reliability was determined using interclass correlation coefficients and standard error of measurement. Forward trunk inclination at 45° yielded a 19% (6.2° P<0.001) increase in trunk rotation and a 40% (25.5° P<0.001) decrease in pelvic rotation when compared to standing. When flexing and extending the spine at a forward trunk inclination of 45° there was a 5% (1.9° P<0.01) and a 4% (1.6° P<0.05) decrease in trunk rotation. Fixing the pelvis increased the trunk rotation by up to 9% (3.3° P<0.001). Inclining the trunk forward and maintaining a neutral spine maximised trunk rotation range of motion (RoM). This has implications for educational programmes intended to maximise sporting performance. Within the clinical setting, unrestricted observation of trunk rotations is considered more appropriate as it may benefit the clinician in determining possible detrimental relative flexibilities that may exist within the body.

Abstract: With accumulating evidence that exercise capacity decreases all-cause mortality independent of adiposity, benefits may be gained by developing cardiorespiratory fitness measures that are specifically and sensitively designed for use with pediatric populations when cardiorespiratory fitness may be a contributing factor for obesity. This study aimed to examine the criterion validity of the Modified Shuttle Test-Paeds (MSTP) as a measure of cardiorespiratory fitness in children, against the gold-standard reference VO2peak, compared to the commonly used field-test 20-m Multi-Stage-Shuttle-Run-Test (20-m MSRT). A cross-sectional pilot study, with 25 school-aged children (age: 6–16 year male/female: 19/5 BMI: 21 ± 9 kg/m2) was employed. Physical measures included: Bruininks-Oseretsky-Test-of-Motor-Proficiency-2nd Edition (BOT2), VO2peak, 20-m MSRT, MSTP, body composition/anthropometry. The mean cardiorespiratory fitness of participants was: VO2peak: 43.8 ± 11.2 (mL/kg/min) 20-m MSRT: 5.48 ± 2.96 (level) MSTP: 22.10 ± 3.05 (no.). A strong predictive relationship was found between the 20-m MSRT and VO2peak (r2 = 0.486, p 0.001) whereas a very strong predictive relationship existed between the newly designed MSTP and VO2peak (r2 = 0.749, p 0.001). Whilst further research with larger study cohorts is needed, this pilot study found the MSTP to have a very high predictive validity for estimating VO2peak in children, suggesting it may be a valid child-specific indicator of cardiorespiratory fitness requiring only a simple equation that is clinically relevant.

Abstract: Schram, BL, Hing, WA, Climstein, M, and Furness, JW. A performance analysis of a stand-up paddle board marathon race. J Strength Cond Res 31(6): 1552–1556, 2017—Stand-up paddle boarding (SUP) is a rapidly growing sport and recreational activity in which little scientific research exists. A review of the literature failed to identify a single article pertaining to the physiological demands of SUP competition. The purpose of this study was to conduct a performance analysis of a national-level SUP marathon race. Ten elite SUP athletes (6 male and 4 female athletes) were recruited from the Stand Up Paddle Surfing Association of Australia to have their race performance in the Australian Titles analyzed. Performance variables included SUP speed, course taken, and heart rate (HR), measured with a 15-Hz global positioning system unit. Results demonstrated that there was a variation in distance covered (13.3–13.9 km), peak speed (18.8–26.4 km·h −1 ), and only moderate correlations ( r = 0.38) of race result to distance covered. Significantly greater amounts of time were spent in the 5- to 10-km·h −1 speed zones ( p ≤ 0.05) during the race. Peak HR varied from 168 to 208 b·min −1 among the competitors with the average HR being 168.6 ± 9.8 b·min −1 . Significantly higher durations were spent in elevated HR zones ( p ≤ 0.05) with participants spending 89.3% of their race within 80–100% of their age-predicted HRmax. Marathon SUP races seem to involve a high aerobic demand, with maintenance of near-maximal HRs required for the duration of the race. There is a high influence of tactical decisions and extrinsic variables to race results. These results provide a greater understanding of the physiological demands of distance events and may assist in the development of specialized training programs for SUP athletes.

Abstract: This study examined older adults’ experiences of participating in the BELL trial, involving 12-weeks of group-based hardstyle kettlebell training. In the BELL trial, 28 insufficiently active older adults (15 women, 13 men, 59-79 years) completed 6 weeks of face-to-face group training, and 6 weeks of home-based training. In-depth semi-structured interviews were audio recorded and transcribed, inductively coded, with themes constructed thematically from patterns of shared meaning. Four higher-order themes were developed that reflect older adults’ experiences participating in a group-exercise program of hardstyle kettlebell training. These included: (1) “It’s one of the best things we’ve done” - enjoying the physical and psychosocial benefits, (2) “It’s improved it tremendously!” - change in a long-term health condition, (3) “It put me on a better course” - overcoming challenges, (4) “I wasn’t just a number” - feeling part of a group/community. Findings highlight the perceived physical and psychological benefits of participating in hardstyle group kettlebell training, the value attributed to being part of an age-matched community of like-minded people engaged in group-exercise, as well as the challenges participants faced, and the sense of achievement in overcoming them. Implications for program design and delivery, and future research are discussed.

Abstract: Hardstyle kettlebell training is characterised by the ballistic two-handed kettlebell swing with outcomes believed to be strongly influenced by swing proficiency. This study examines the effect of four months hardstyle kettlebell training on the force profile of the two-handed kettlebell swing, and peak ground reaction force during a kettlebell deadlift in older adults. These data will help inform healthcare providers and coaches about the use and prescription of kettlebell exercises with older adults. Five males and five females years of age who participated in the BELL trial were recruited. Two-handed hardstyle swings were performed with 8-16 kg, and deadlifts with 8-32 kg. Ground reaction force (GRF) was obtained from a floor-mounted force platform. Force-time curves (FTCs), peak force, forward force relative to vertical force, rate of force development (RFD), and swing cadence were investigated. Results were compared with the same data variables collected from the participants in an exploratory pre-intervention study, conducted approximately seven months before the present study. Participants completed approximately 90 kettlebell training sessions during a four-month training intervention. Participants used kettlebells to perform 3779 ± 802 swings, 923 ± 251 cleans, 825 ± 309 snatches and 744 ± 178 deadlifts during group-training sessions. Peak ground reaction force during kettlebell swings did not significantly change with any kettlebell weight. There was a significant 3% increase in the magnitude of forward force during 8 kg swings, and a significant 3% decrease in forward force during 16 kg swings. There were large significant improvements in swing cadence with a mean increase of three swings per minute and a small non-significant increase in RFD. Change in kettlebell swing force-time curve profiles were small. Change in peak ground reaction force during deadlifts were moderate to large. All participants increased in grip strength following training, with the magnitude of change greater than the minimum clinically important difference for seven participants. All participants had significant increases in multiple secondary outcomes. Group-based and online kettlebell training is likely to be ineffective for improving the force profile of the hardstyle kettlebell swing in older adults. Insufficiently active older adults engaged in high-volume kettlebell training performed 3-5 times weekly, can however expect to see clinically meaningful improvements in health-related physical fitness irrespective of swing proficiency, and have increased confidence with heavy lifting tasks. Results of this study suggest that beyond safe and competent performance, striving to optimise hardstyle swing technique may provide no additional benefit to clinical outcomes in older adults.

Abstract: In New Zealand, a new approach to manual therapy of the cervical spine has integrated physiotherapy and osteopathy techniques. The combination of the philosophies of these two professions has added a new dimension to the management of cervical spine pain. Emphasis is placed on issues of safety, such as the degree of cervical rotation and comfort for both the patient and the therapist. This is combined with biomechanical considerations, which have made the teaching and learning of these manipulative techniques less complicated and easily progressed from palpation to mobilization and onto manipulation. Appropriate patient screening and selection identified through thorough subjective and objective assessments are important aspects of this approach and reflective interpretation of all clinical findings is essential. The refinement of cervical joint positioning and an increased anatomical awareness have led to the utilization of new upper cervical high-velocity thrust techniques. Consequently, it is envisaged that an increase in the safety and specificity of cervical manipulative techniques is achieved.

Abstract: This study aimed to investigate reasons for ceasing participation in aqua-based exercise among older adults with osteoarthritis (OA). Eleven adults over 60 years of age with OA participated in one of two focus groups, during which they discussed barriers to aqua-based exercise and the potential benefits of this exercise mode. Each focus group was audiotaped, transcribed and then analysed using the general inductive thematic approach. The investigators reached a consensus on all coding categories and then identified themes. Key barriers identified were: a lack of suitable classes insufficient instructor knowledge, which often led to increased pain cold water and the changing facilities. Key perceived benefits included increased physical ability in water and social interaction. A greater understanding of reasons for ceasing participation in aqua-based exercise among older adults with OA may help facilitate development of suitable exercise programs that minimise barriers for this group.

Abstract: Stand-up paddle boarding (SUP) is a recreational activity and sport that has grown exponentially, with participation increasing from 1.1 million in 2010 to 2.8 million in 2014 in the United States alone. Despite this growth in participation, SUP remains underresearched with regard to injury epidemiology. To investigate injury epidemiology (severity, location, type, mechanism) in SUP. Descriptive epidemiology study. An open-source online survey was administered to active SUP participants internationally. The survey captured information relevant to demographics, participation, and injury history over the past 12 months. Of 240 participants included in the data analysis, 67.1% were males, and 54.6% were involved in competition. Participants spent a mean 192.6 ± 179.5 hours participating in SUP per year, most commonly for fun and fitness (43.3%) at the beach or bay (63.0%). A total of 95 participants had sustained at least 1 injury. A total of 161 injuries were recorded, resulting in an injury rate of 3.63 (95% CI, 3.04-4.16) per 1000 hours of SUP. The shoulder/upper arm was the most frequently injured body location, accounting for 32.9% of all injuries, followed by the lower back (14.3%) and the elbow/forearm (11.8%). The most common injury types were to muscle/tendon (50.4%), joint/ligament (22.6%), and skin (14.2%). Endurance paddling was the most frequently reported mechanism of injury (34.5%), followed by contact with a paddler’s own board (20.1%) and sprint paddling (9.3%). Key risk factors for sustaining an injury were age years, competitive status, and participating for .8 hours/week, as well as using SUP for racing. This is the first study to report injury epidemiology for SUP. It is evident that both sexes participate in SUP for fun, fitness, and competition. With regard to injuries, the shoulder, lower back, and elbow are the most injury prone older age, competitive status, and longer hours of participation all influenced the chance of injury. Findings from this study provide the foundation for injury prevention strategies.

Abstract: Surfing is one of the most popular outdoor aquatic activities in Australia with an estimated 2.7 million recreational surfers however, Australia has long been recognized as having the highest incidence of melanoma in the world, and it is the most common type of cancer in young Australians. The aim of this study was to investigate the lifetime prevalence of non-melanoma [basal cell carcinoma (BCC), squamous cell carcinoma (SCC)] and melanoma skin cancers in Australian recreational and competitive surfers. Australian surfers were invited to complete an online surveillance survey to determine the lifetime prevalence of non-melanoma and melanoma skin cancers. A total of 1348 surfers (56.9% recreational) participated in this study, of which 184 surfers reported a skin cancer (competitive n = 96, recreational n = 87). Of non-melanoma and melanoma cancers reported, BCC was the most common (6.8%), followed by melanoma (1.4%) and SCC (0.6%). The relative risk was higher (P < 0.001) in competitive vs. recreational surfers [OR 1.74 (CI 1.28-2.31)]. There was a higher (P < 0.05) number of skin cancers reported on the face (23.5%), back (16.4%) and arms (12.4%). There were significant trends (P < 0.001) in reported skin cancers between competitive and recreational surfers, as well as significantly (P < 0.001) more skin cancers reported in males (14.6%) than females (9.4%). Based upon these findings, in iduals who surf are advised to regularly utilize sun protection strategies (avoid peak ultraviolet radiation (10 am-3 pm), rashvest, hat and sunscreen) and primary care physicians are recommended to regularly screen their patients who surf.

Abstract: Gait analysis is one aspect of evaluation in ambulatory children with cerebral palsy (CP). Ankle-foot orthoses (AFOs) improve gait and alignment through providing support. An alternative and under-researched orthosis are sensomotoric orthoses (SMotOs). The Edinburgh Visual Gait Score (EVGS) is a valid observational gait analysis scale to measure gait quality. The aim of this study was to use the EVGS to determine what effect AFOs and SMotOs have on gait in children with CP. The inclusion criteria were: mobilizing children with a CP diagnosis, no surgery in the past six weeks, and currently using SMotOs and AFOs. Eleven participants were videoed walking 5 m (any order) barefoot, in SMotOs and AFOs. Of the participants (age range 3–13 years, mean 5.5 ± 2.9), two were female and six used assistive devices. Seven could walk barefoot. Participants had spastic diplegia (4), spastic quadriplegia (6), and spastic dystonic quadriplegia (1). Gross Motor Functional Classification System (GMFCS) levels ranged I–IV. The total score for SMotOs (7.62) and AFOs (14.18) demonstrated improved gait when wearing SMotOs (no significant differences between barefoot and AFOs). SMotOs may be a viable option to improve gait in this population. Additional study is required but SMotOs may be useful in clinical settings.

Abstract: The Ballistic Exercise of the Lower Limb (BELL) trial examined efficacy and safety of a pragmatic hardstyle kettlebell training program in older adults. Insufficiently active men and women aged 59-79 years, were recruited to a 6-month repeated measures study, involving 3-months usual activity and 3-months progressive hardstyle kettlebell training. Health-related physical fitness outcomes included: grip strength [GS], 6-min walk distance [6MWD], resting heart rate [HR], stair-climb [SC], leg extensor strength [LES], hip extensor strength [HES], Sit-To-Stand [STS], vertical jump [CMVJ], five-times floor transfer [5xFT], 1RM deadlift, body composition (DXA), attendance, and adverse events. Sixteen males (68.8 ± 4.6 yrs, 176.2 ± 7.8 cm, 90.7 ± 11.0 kg, 29.2 ± 2.6 kg/m 2 ) and sixteen females (68.6 ± 4.7 yrs, 163.9 ± 5.4 cm, 70.4 ± 12.7 kg, 26.3 ± 4.9 kg/m 2 ) were recruited. Compliance to the supervised exercise program was very high (91.5%). Kettlebell training increased GS (R: MD = 7.1 kg 95% CI [4.9, 9.3], p 0.001, L: MD = 6.3 kg 95% CI [4.1, 8.4], p 0.001), 6MWD (41.7 m, 95% CI [17.9, 65.5], p .001), 1RM (16.2 kg, 95% CI [2.4, 30.0], p = 0.013), 30s STS (3.3 reps, 95% CI [0.9, 5.7], p = 0.003), LES (R: MD = 61.6 N, 95% CI [4.4, 118.8], p = 0.028), HES (L: MD = 21.0 N, 95% CI [4.2, 37.8], p = 0.007), appendicular skeletal lean mass (MD = 0.65 kg, 95% CI [0.08, 1.22], p = 0.016), self-reported health change (17.1%, 95% CI [4.4, 29.8], p = 0.002) and decreased SC time (2.7 sec, 95% CI [0.2, 5.2], p = 0.025), 5xFT time (6.0 sec, 95% CI [2.2, 9.8], p 0.001) and resting HR (7.4 bpm, 95% CI [0.7, 14.1], p = 0.032). There were four non-serious adverse events. Mean in idual training load for group training sessions during the trial was 100,977 ± 9,050 kg. High-intensity hardstyle kettlebell training was well tolerated and improved grip strength and measures of health-related physical fitness in insufficiently active older adults.

Abstract: The introduction of enhanced recovery pathways has demonstrated both patient and organisational benefits. However, enhanced recovery pathways implemented for total hip arthroplasty (THA) and total knee arthroplasty (TKA) vary between health-care organisations, as do their measures of success, particularly patient-related outcomes. Despite inpatient functional recovery being essential for safe and timely hospital discharge, there is currently no gold standard method for its assessment, and the research undertaken to establish prognostic factors is limited. This study aimed to identify prognostic factors and subsequently develop prognostic models for inpatient functional recovery following primary, unilateral THA and TKA identify factors associated with acute length of stay and assess the relationships between inpatient function and longer-term functional outcomes. Correlation and multiple regression analyses were used to determine prognostic factors for functional recovery (assessed using the modified Iowa Level of Assistance Scale on day 2 post-operatively) in a prospective cohort study of 354 patients following primary, unilateral THA or TKA. For the overall cohort and TKA group, significant prognostic factors included age, sex, pre-operative general health, pre-operative function, and use of general anaesthesia, local infiltration analgesia, and patient-controlled analgesia. In addition, arthroplasty site was a prognostic factor for the overall cohort, and surgery duration was prognostic for the TKA group. For the THA group, significant prognostic factors included pre-operative function, Risk Assessment and Prediction Tool score, and surgical approach. Several factors were associated with acute hospital length of stay. Inpatient function was positively correlated with functional outcomes assessed at 6 months post-operatively. Prognostic models may facilitate the prediction of inpatient flow thus optimising organisational efficiency. Surgical prognostic factors warrant consideration as potential key elements in enhanced recovery pathways, associated with early post-operative functional recovery. Standardised measures of inpatient function serve to evaluate patient-centred outcomes and facilitate the benchmarking and improvement of enhanced recovery pathways.

Abstract: A consensus clinical reasoning framework for best practice for the examination of the cervical spine region has been developed through an iterative consultative process with experts and manual physical therapy organisations. The framework was approved by the 22 member countries of the International Federation of Orthopaedic Manipulative Physical Therapists (October 2012). The purpose of the framework is to provide guidance to clinicians for the assessment of the cervical region for potential of Cervical Arterial Dysfunction in advance of planned management (inclusive of manual therapy and exercise interventions). The best, most recent scientific evidence is combined with international expert opinion, and is presented with the intention to be informative, but not prescriptive and therefore as an aid to the clinician's clinical reasoning. Important underlying principles of the framework are that 1] although presentations and adverse events of Cervical Arterial Dysfunction are rare, it is a potentially serious condition and needs to be considered in musculoskeletal assessment 2] manual therapists cannot rely on the results of one clinical test to draw conclusions as to the presence or risk of Cervical Arterial Dysfunction and 3] a clinically reasoned understanding of the patient's presentation, including a risk:benefit analysis, following an informed, planned and in idualised assessment, is essential for recognition of this condition and for safe manual therapy practice in the cervical region. Clinicians should also be cognisant of jurisdictionally specific requirements and obligations, particularly related to patient informed consent, when intending to use manual therapy in the cervical region.

Abstract: Non-invasive blood pressure (BP) measurement has been used clinically for over a century to diagnose hypertension. Compared with the auscultatory technique, the oscillometric technique requires less professional training and is widely used in automatic BP measurement devices. Currently, most of these devices measure and record litude of cuff pressure oscillation, and then calculate diastolic and systolic pressure using characteristic ratios and designed algorithms. A finite element (FE) model is developed to study the biomechanical basis of this technique. The model identifies that errors were caused by mechanical factors of the soft tissue and the shape of the arm. By personalizing the parameters for each patient, the accuracy of the measurement will be improved for all age groups.

Abstract: Validity of a clinical test can be defined as the extent to which the test actually assesses what it is intended to assess. In order to investigate the validity of manual physical assessment of the spine, it is therefore essential to establish what physical therapists intend to assess when they are applying these tests. The aims of this study were to (1) establish what manual physical therapists are intending to assess while applying passive intervertebral motion tests and (2) examine the face validity and content validity for manual physical assessment of the spine. We surveyed 1502 members of the national manual physical therapist organisations of New Zealand and the United States of America using a web-based survey instrument. Sixty-six percent of 466 respondents believed passive accessory intervertebral motion (PAIVM) tests were valid for assessing quantity of segmental motion, and 76% believed passive physiologic intervertebral motion (PPIVM) tests were valid for assessing quantity of segmental motion. Ninety-eight percent of manual physical therapists base treatment decisions at least in part on the results of segmental motion tests. Quality of resistance to passive segmental motion was considered of greater importance than quantity of kinematic motion during PAIVM tests, while the quality of complex kinematic motion was considered of greater importance than quantity of displacement kinematics during PPIVM tests. Manual physical therapists accept the face validity of manual physical assessment of spinal segmental motion to a great extent, however a minority voice scepticism. Content validity is dominated by concepts of segmental kinematics and the force-displacement relationship. Intent of assessment does, however, vary widely between therapists. These data will inform the design of concurrent validity studies. Further work is recommended to increase consistency of intent, methodology and terminology in manual physical assessment of the spine.

Abstract: The overall purpose of this study was to examine the relationship between motor proficiency and health-related fitness in children. In addition, the study aimed to determine if particular combinations of motor skills have a stronger relationship with in idual health-related fitness measures. Seventy-seven children (F:28, M:49) (mean age: 11.19 ± 2.74 years) participated in this prospective cohort study. Physical measures included the following: motor proficiency (Bruininks-Oseretsky Test of Motor Proficiency, Second Edition), body mass index (BMI), waist circumference, blood pressure, heart rate and VO(2) peak (mL/kg/min). After factoring in age, motor proficiency as a combined total score had a strong negative relationship with the health-related fitness measures of BMI (r (2) = 0.62, P < 0.001) and waist circumference (r (2) = 0.72, P < 0.001) and a strong positive relationship with VO2 peak (r (2) = 0.78, P = 0.002). Children with lower motor proficiency (≤25th percentile) had a significantly larger mean waist circumference (M = 13.85 cm, 95% confidence interval (CI) (2.05, 25.66), P = 0.01), heavier weight (M = 22.17 kg, 95% CI (2.44, 41.91), P = 0.02) and higher BMI (M = 5.10 kg/m(2) , 95% CI (0.33, 9.87), P = 0.03) than children with higher motor proficiency (≤75th percentile). Motor proficiency, once corrected for age, is significantly related to a number of health-related measures in children and should therefore be considered a focus for investigation for children with poor health-related fitness (e.g. high BMI and waist circumference percentiles or low cardiorespiratory fitness), as motor incompetence could be an underlying contributing factor to a child's poor physical health.

Abstract: Iliotibial band friction syndrome (ITBFS) is a common injury of the lateral aspect of the knee particularly in runners, cyclists and endurance sports. A number of authors suggest that ITBFS responds well to conservative treatment, however, much of this opinion appears anecdotal and not supported by evidence within the literature. The purpose of this paper is to provide a systematic review of the literature pertaining to the conservative treatment of ITBFS. A search to identify clinical papers referring to the iliotibial band (ITB) and ITBFS was conducted in a number of electronic databases using the keyword: iliotibial. The titles and abstracts of these papers were reviewed to identify papers specifically detailing conservative treatments of ITBFS. The PEDro Scale, a systematic tool used to critique randomized controlled trials (RCTs), was employed to investigate both the therapeutic effect of conservative treatment of ITBFS and also to critique the methodological quality of available RCTs examining the conservative treatment of ITBFS. With respect to the management of ITBFS, four RCTs were identified. The interventions examined included the use of non-steroidal anti-inflammatory drugs (NSAIDs), deep friction massage, phonophoresis versus immobilization and corticosteroid injection. This review highlights both the paucity in quantity and quality of research regarding the conservative treatment of ITBFS. There seems limited evidence to suggest that the conservative treatments that have been studied offer any significant benefit in the management of ITBFS. Future research will need to re-examine those conservative therapies, which have already been examined, along with others, and will need to be of sufficient quality to enable accurate clinical judgements to be made regarding their use.

Abstract: There are an estimated 37 million surfers worldwide, with 2.5 million recreational surfers in Australia. The recreational activity and sport of surfing has grown dramatically since the 1960s, but scientific research has been poorly mirrored in comparison with most other mainstream sports. To identify the incidence, severity, location, type, and mechanism of acute injuries in recreational and competitive surfers over a 12-month period. Descriptive epidemiology study. An online survey using an open-source survey application was utilized. The survey consisted of 2 primary sections: Section 1 included demographic information and participation levels (age, height, weight, hours surfed, competitive level) section 2 incorporated injury type, mechanism, severity, and injury management. A total of 1348 participants (91.3% males 43.1% competitive surfers) were included in data analysis. A total of 512 acute injuries were classified as major, providing an incidence proportion of 0.38 (CI, 0.35-0.41) acute injuries per year. The incidence rate was calculated to be 1.79 (CI, 1.67-1.92) major injuries per 1000 hours of surfing. The shoulder, ankle, and head/face regions had the highest frequencies of acute injury, representing 16.4%, 14.6%, and 13.3%, respectively. Injuries were predominantly of muscular, joint, and skin origin, representing 30.3%, 27.7%, and 18.9%, respectively. Skin injuries were primarily a result of direct trauma, while joint and muscular injuries were mainly a result of maneuvers performed and repetitive actions. Key risk factors that increased the incidence of sustaining an acute injury included competitive status, hours surfed ( .5 hours/week), and the ability to perform aerial maneuvers. The incidence proportion for surfers completing aerial maneuvers was calculated to be 0.48 (CI, 0.39-0.58) major injuries per year, this being the highest incidence proportion irrespective of competitive status. This is the largest surfing-specific survey that included both recreational and competitive surfers conducted in Australia to date. The shoulder, ankle, head, and face were identified as the key regions where acute injuries occur in surfers. This research may aid in reducing the occurrence of injury through musculoskeletal screening in these key injury-prone regions and through the use of sport-specific strength training and conditioning.

Abstract: This study examined older adults’ experiences of participating in the Ballistic Exercise of the Lower Limb (BELL) trial, involving 12-weeks of group-based hardstyle kettlebell training. In the BELL trial, 28 insufficiently active older adults (15 women, 13 men, 59–79 years) completed six weeks of face-to-face group training, and six weeks of home-based training. In-depth semi-structured interviews were audio recorded, transcribed, and inductively coded, with themes constructed from patterns of shared meaning. Four higher-order themes were developed that reflect older adults’ experiences participating in a group-exercise program of hardstyle kettlebell training. These included: (1) “It’s one of the best things we’ve done”—enjoying the physical and psychosocial benefits, (2) “It’s improved it tremendously!”—change in a long-term health condition, (3) “It put me on a better course”—overcoming challenges, and (4) “I wasn’t just a number”—feeling part of a group/community. Findings highlight the perceived physical and psychological benefits of older adults participating in hardstyle group kettlebell training, and the value attributed to being part of an age-matched community of like-minded people engaged in group exercise. Implications for program design and delivery, and future research, are discussed.

Abstract: Background: Backpack loads of school students during school days have been suggested to range from 10% to as high as 25% of their body weight and may have a negative impact on their body. The aim of this review was to identify and review studies that have examined impacts of contemporary backpack loads on school children. Methods: A systematic search was conducted of the literature using key search terms. After relevant studies published in recent years were selected using strict inclusion and exclusion criteria, the studies were critically appraised and relevant data were extracted and tabulated prior to conducting a critical narrative synthesis of findings. Results: Twenty-one studies were included, ranging in methodological quality from poor to good (critical appraisal scores 22% to 77%). Students carried on average over 15% of their own body weight, which caused biomechanical and physiological adaptations that could increase musculoskeletal injury risk, fatigue, redness, swelling and discomfort. Conclusion: Considering the limited methodological quality and variations in foci across studies, further research is needed to elucidate: (1) the loads students carry around on a school day in their school backpacks and (2) the biomechanical, physiological and physical effects of load carriage on students.

Abstract: The purpose of this explanatory retrospective case study was to report clinically significant increases in bone mineral density in a female and a male over 70 years of age with osteoporosis, following 16 weeks of hardstyle kettlebell training. Both case subjects were insufficiently active prior to participating in the BELL trial. Subjects trained five days a week accruing a large training load volume (calculated as kettlebell mass multiplied by repetitions performed) during structured group-based classes (74,872 kg and 110,132 kg, respectively). Regional dual-energy X-ray absorptiometry was used to assess BMD at the hip and lumbar spine. Increases in BMD of 12.7% and 5.9% at the femoral neck and lumbar spine (L2-L4) respectively were observed for the female, and 2.5% and 6.0% respectively for the male. Magnitude of change in BMD (g/cm 2 ) at the lumbar spine was 2.0 and 1.9 times larger than the least significant change for the female and male respectively, and sufficient to advance the female subjects’ status from osteoporosis to osteopenia. Although these results do not show a definitive causal relationship between kettlebell training and increased BMD, further investigation of the effects of kettlebell training on BMD in older adults with osteoporosis and osteopenia is warranted.

Abstract: The Abductor hallucis muscle (AbdH) plays an integral role during gait and is often affected in pathological foot conditions. The aim of this study was to evaluate the within and between-session intra-tester reliability using diagnostic ultrasound of the dorso-plantar thickness, medio-lateral width and cross-sectional area, of the AbdH in asymptomatic adults. The AbdH muscles of thirty asymptomatic subjects were imaged and then measured using a Philips HD11 Ultrasound machine. Interclass correlation coefficients (ICC) with 95% confidence intervals (CI) were used to calculate both within and between session intra-tester reliability. The within-session reliability results demonstrated for dorso-plantar thickness an ICC of 0.97 (95% CI: 0.99–0.99) medio-lateral width an ICC: of 0.97 (95% CI: 0.92–0.97) and cross-sectional area an ICC of 0.98 (95% CI: 0.98–0.99). Between-session reliability results demonstrated for dorso-plantar thickness an ICC of 0.97 (95% CI: 0.95 to 0.98) medio-lateral width an ICC of 0.94 (95% CI 0.90 to 0.96) and for cross-sectional area an ICC of 0.79 (95% CI 0.65 to 0.88). Diagnostic ultrasound has the potential to be a reliable tool for evaluating the AbdH muscle in asymptomatic subjects. Subsequent studies may be conducted to provide a better understanding of the AbdH function in foot and ankle pathologies.

Abstract: Stand-up paddle boarding (SUP) is a rapidly growing activity where only anecdotal evidence exists for its proposed health and fitness benefits. The purpose of this study was to profile elite and recreational SUP with respect to anthropometric, physiological and musculoskeletal measurements. A total of 30 SUP participants (15 recreational, 15 elite) and 15 sedentary controls participated in this study. Elite and recreational (rec) SUP participants had significantly lower body fat than sedentary (sed) in iduals, elite had significantly higher HDL and significantly lower triglycerides than other groups during lipid profiling (P > 0.05). There were significant differences (P > 0.05) between all groups in maximal oxygen uptake (elite 43.7, s = 5.89 ml · kg(-1) · min(-1) vs. rec 31.9, s = 7.7 ml · kg(-1) · min(-1) vs. sed 20.4, s = 3.7 ml · kg(-1) · min(-1)) and anaerobic power outputs (35.7, s = 11.1 W vs. 25.0, s = 11.7 W vs. 13.5, s = 7.1 W). The elite group displayed significantly longer endurance than the recreational and sedentary group in the prone bridge (elite 253.4, s = 67.6 s vs. rec 165.6, s = 42.2 s vs. sed 69.7, s = 31.2 s), right-sided bridge (elite 107.9, s = 34.0 s vs. recreational 68.2, s = 24.1 s vs. sed 34.6, s = 15.5 s), left-sided bridge (elite 99.8, s = 24.9 s vs. rec 68.2, s = 27.2 s vs. sed 32.5, s = 15.2 s) and Biering Sorensen test (elite 148.8, s = 35.4 s vs. rec 127.2, s = 43.2 s vs. sed 71.1, s = 32.9 s). Elite SUP had significantly better static and dynamic postural control when compared to the other groups. This study demonstrates the anthropometric, physiological and musculoskeletal values representative of elite and recreational SUP. SUP appears to be associated with increased levels of aerobic and anaerobic fitness, increased static and dynamic balance and a high level of isometric trunk endurance.

Abstract: Measure changes in pain and disability of primary care shoulder pain patients over a 12-month period. A non-randomized audit with repeated measures of pain and disability at 3 weeks, 3, 6 and 12 months. Of 208 patients, 161 agreed to participate with 96.9%, 98.1%, 86.3%, 83.9% follow-up at 3 weeks, at 3, 6 and 12 months, respectively. Mean age was 44 years, mean symptom duration 3.6 months. PATIENTS were treated with protocol driven corticosteroid injection and community based care. Primary outcome measure was the Shoulder Pain and Disability index (SPADI) questionnaire. Based on the SPADI and minimal clinically important difference (MCID), outcomes were categorized into: total recovery, 90% or more improved, better, unchanged and worse. There was significant reduction of pain and disability at 3 weeks (p < 0.001), no change at the 3- and 6-month follow-up and a significant reduction at the 12-month follow-up (p < 0.001). Excellent outcomes were achieved by 32.9% and 45.3%, and a poor clinical outcome resulted for 32.8% and 14.9% at the 3- and 12-month follow-up, respectively. Though there was significant improvement at the 3-week and 12-month follow-up, 45% achieved an excellent outcome and a 16.7% of patients were the same or worse than baseline at 12 months.

Abstract: To determine the reliability of patient reports of pain intensity during the application of physical tests. A single examiner required participants to use the numeric pain rating scale (NPRS) to report the intensity of pain provoked during physical testing of the hip. Standardized versions of 14 physical tests were used on 18 people with hip pain. Tests were repeated at 1 hour and 2-7 days later. Within- and between-session reliability of reports of pain intensity was calculated using intraclass correlation coefficients (ICCs) and Lin's concordance correlation coefficients (CCCs). Standard errors of measurement (SEMs) were calculated. ICC/CCC values for within-session reports of pain intensity ranged from 0.34 (95% confidence interval [95% CI] -0.08, 0.66) to 0.88 (95% CI 0.73, 0.95). Patients demonstrated "substantial" or "almost perfect" reliability in reporting pain intensity with 9 of 14 tests and "moderate" reliability with 3 tests. Two tests were unreliable (ICC 0.35 and 0.34). ICC/CCC values for between-session reports of pain intensity ranged from -0.05 (95% CI -0.42, 0.34) to 0.84 (95% CI 0.44, 0.95). Patients demonstrated substantial or almost perfect reliability in reporting pain intensity with 11 of 14 tests. Two tests were unreliable (ICC 0.26 and -0.05). The average SEM value of 0.9 points on the NPRS was the same for both within- and between-session testing (range 0.6-1.6). Patient reports of the intensity of pain provoked by physical tests are sufficiently reliable to be clinically useful. However, the SEM of 0.9 points should be considered when precise calculations of changes in pain intensity are important.

Abstract: External auditory exostosis (EAE) has previously only been shown to occur in cold water surfers. We assessed young surfers living and surfing in Queensland, Australia, for EAE in water temp ranges from 20.6 °C (69.1 °F, Winter) to 28.2 °C (82.8 °F, Summer). All participants underwent a bilateral otoscopic examination to assess the presence and severity of EAE. A total of 23 surfers participated with a mean age of 35.4 years (8.3 years) and a mean surfing experience of 20.0 years (9.9 years). Nearly two-thirds of participants (n = 14, 60.9%) had regular otological symptoms, most commonly water trapping (n = 13, 56.5%), pain (n = 8, 34.8%), and hearing loss (n = 6, 26.1%). Only 8.7% (n = 2) of all surfers reported regular use of protective equipment (e.g., earplugs) on a regular basis. The overall prevalence of exostosis was 69.6% (n = 16), and the majority (n = 12, 80.0%) demonstrated bilateral lesions of a mild grade ( % obstruction of the external auditory canal). This is the first study assessing EAE in young surfers exposed to only warm waters (above 20.6 °C). The prevalence of EAE in this study highlights that EAE is not restricted to cold water conditions, as previously believed. Warm water surfing enthusiasts should be screened on a regular basis by their general medical practitioner and utilize prevention strategies such as earplugs to minimize exposure to EAE development.

Abstract: Contrast therapy is a strategy that is widely utilised in a number of sporting codes to aid recovery. This wide use might suggest that contrast therapy is an effective recovery modality however support for this assumption appears to be mainly anecdotal. The purpose of this paper is to review the efficacy of contrast therapy. To achieve this objective, a systematic review of randomised controlled trials (RCTs) that have specifically evaluated the therapeutic efficacy of contrast therapy was performed. A search to identify appropriate literature was conducted across a number of electronic databases. The titles and abstracts of the papers identified were reviewed to select papers specifically relating to contrast therapy. Twelve RCTs met the inclusion and exclusion criteria. The PEDro Scale, a systematic tool used to critique RCTs, was employed to critique the methodological quality of these studies. This review highlights both the lack in quantity and quality of research regarding the efficacy of contrast therapy for sports recovery. There appears to be insufficient evidence that contrast therapy aids in recovery and the limited methodological quality of the reviewed studies makes it difficult to draw clear conclusions about this form of therapy. Future research needs to re-examine the use of contrast therapy and in particular whole body immersion recovery strategies within the appropriate sports setting. This research will need to be of sufficient quality to enable appropriate conclusions to be made with regards to its use as a recovery strategy.

Abstract: The aim was to critically evaluate the literature investigating strength training interventions in the treatment of plantar fasciitis and improving intrinsic foot musculature strength. A search of PubMed, CINHAL, Web of Science, SPORTSDiscus, EBSCO Academic Search Complete and PEDRO using the search terms plantar fasciitis, strength, strengthening, resistance training, intrinsic flexor foot, resistance training. Seven articles met the eligibility criteria. Methodological quality was assessed using the modified Downs and Black checklist. All articles showed moderate to high quality, however external validity was low. A comparison of the interventions highlights significant differences in strength training approaches to treating plantar fasciitis and improving intrinsic strength. It was not possible to identify the extent to which strengthening interventions for intrinsic musculature may benefit symptomatic or at risk populations to plantar fasciitis. There is limited external validity that foot exercises, toe flexion against resistance and minimalist running shoes may contribute to improved intrinsic foot musculature function. Despite no plantar fascia thickness changes being observed through high-load plantar fascia resistance training there are indications that it may aid in a reduction of pain and improvements in function. Further research should use standardised outcome measures to assess intrinsic foot musculature strength and plantar fasciitis symptoms.

Abstract: Ultrasound imaging (USI) is gaining popularity as a tool for assessing nerve excursion and is becoming an important tool for the assessment and management of entrapment neuropathies. This systematic review aimed to identify current methods and report on the reliability of using USI to examine nerve excursion and identify the level of evidence supporting the reliability of this technique. A systematic search of five electronic databases identified studies assessing the reliability of using USI to examine nerve excursion. Two independent reviewers critically appraised and assessed the methodological quality of the identified articles. Eighteen studies met the eligibility criteria. The majority of studies were of "moderate" or "high" methodological quality. The overall analysis indicated a "strong" level of evidence of moderate to high reliability of using USI to assess nerve excursion. Further reliability studies with consistency of reporting are required to further strengthen the level of evidence.

Abstract: To investigate physiotherapist agreement in rating movement quality during lower extremity functional tests using two visual rating methods and physiotherapists with differing clinical experience. Clinical measurement. Six healthy in iduals were rated by 44 physiotherapists. These raters were in three groups (inexperienced, novice, experienced). Video recordings of all six in iduals performing four lower extremity functional tests were visually rated (dichotomous or ordinal scale) using two rating methods (overall or segment) on two occasions separated by 3-4 weeks. Intra and inter-rater agreement for physiotherapists was determined using overall percentage agreement (OPA) and the first order agreement coefficient (AC1). Intra-rater agreement for overall and segment methods ranged from slight to almost perfect (OPA: 29-96%, AC1: 0.01 to 0.96). AC1 agreement was better in the experienced group (84-99% likelihood) and for dichotomous rating (97-100% likelihood). Inter-rater agreement ranged from fair to good (OPA: 45-79% AC1: 0.22-0.71). AC1 agreement was not influenced by clinical experience but was again better using dichotomous rating. Physiotherapists' visual rating of movement quality during lower extremity functional tests resulted in slight to almost perfect intra-rater agreement and fair to good inter-rater agreement. Agreement improved with increased level of clinical experience and use of dichotomous rating.

Abstract: This study explored current physiotherapy practice trends for management of children who are overweight or obese. The professional needs of physiotherapists working with this population were also assessed, including the perceived need for physiotherapy clinical guidelines for prevention and management of children with obesity. A cross-sectional survey design was used, with questionnaires purposefully distributed through 13 key physiotherapy services throughout Australia. Snowball s ling resulted in completed questionnaires from 64 physiotherapists who provided services to children. Half (n = 33, 52%) of respondents provided services specifically to overweight or obese children. Of those providing services, one-quarter had prior training specific to working with this population. Most used multi-disciplinary models (n = 16, 76%) and provided under 5 h of obesity-related services each week (n = 29, 88%). Half (n = 16, 49%) used body mass index as an outcome measure but more (n = 25, 76%) used bodyweight. Only 14 (42%) assessed motor skills. The majority of respondents (n = 57, 89%) indicated a need for physiotherapy guidelines to best manage overweight and obese children. Professional development priorities included: ‘Educating children and families’, ‘Assessment methods’ and ‘Exercise prescription’ for overweight and obese children. This data provides workforce intelligence to guide future professional training and inform development of clinical guidelines for physiotherapists in prevention and management of children with obesity and related chronic disease.

Abstract: To investigate visual rating of pelvis and knee position in young athletes during lower extremity functional tests. Pelvis and knee alignment, in 23 athletes, was visually rated by 66 physiotherapists. Peak two-dimensional (2D) and three-dimensional (3D) kinematics were also quantified. Ratings were compared to consensus visual ratings of an expert panel. The consensus ratings were also compared to peak kinematics. Reliability was determined using percentage agreement (PA) and the first order agreement coefficient (AC1). Sensitivity, specificity, diagnostic odds ratio (DOR) and differences in kinematics between groups based on the expert visual ratings were calculated to assess rating validity. Mean intra-rater agreement was substantial (PA: 79-88%, AC1: 0.60-0.78). Inter-rater agreement ranged from fair to substantial (PA: 67-80% AC1: 0.37-0.61). Sensitivity (≥80%) and specificity (≥50%) were acceptable for all tests except the Drop Jump. Experience (DOR 1.6-2.8 times better) and slower movement (4.9 times better) improved rating accuracy. Peak 3D and 2D kinematics were different between groups rated as having good versus poor alignment by the experts. Visual rating by physiotherapists is a valid tool for identifying young athletes with poor frontal plane dynamic pelvis and knee alignment.

Abstract: Recovery from exercise can be an important factor in performance during repeated bouts of exercise. In a tournament situation, where athletes may compete numerous times over a few days, enhancing recovery may provide a competitive advantage. One method that is gaining popularity as a means to enhance post-game or post-training recovery is immersion in water. Much of the literature on the ability of water immersion as a means to improve athletic recovery appears to be based on anecdotal information, with limited research on actual performance change. Water immersion may cause physiological changes within the body that could improve recovery from exercise. These physiological changes include intracellular-intravascular fluid shifts, reduction of muscle oedema and increased cardiac output (without increasing energy expenditure), which increases blood flow and possible nutrient and waste transportation through the body. Also, there may be a psychological benefit to athletes with a reduced cessation of fatigue during immersion. Water temperature alters the physiological response to immersion and cool to thermoneutral temperatures may provide the best range for recovery. Further performance-orientated research is required to determine whether water immersion is beneficial to athletes.

Participants were five children with cerebral palsy who were currently attending a rural school. Each child received an 8-week rehabilitation programme involving an Interactive Virtual Reality Exercise (IREX) system. The IREX was placed in the child's school for the duration of the intervention. Each child's programme was designed by a physiotherapist but supervised by a teacher aide at the school. Feasibility of the intervention was assessed through a questionnaire completed by the child and an interview conducted with the teacher supervisor. The children all rated the IREX intervention as fun, easy to use, and beneficial for their arm. Categories from the supervisor interviews centred on resolving technical issues, the enjoyment of taking part due to the child's progress, and the central role of interacting with the child. Input from the research physiotherapist was critical to the success of the intervention. The IREX is feasible to implement in a school-based setting supervised by teachers. This provides an option for delivering physiotherapy to children in isolated areas who do not receive on-going therapy. Implication for Rehabilitation Virtual rehabilitation programmes using the IREX are feasible in a school-based setting. The negative impact of technical difficulties is likely to be overcome by the user's enjoyment and rehabilitation benefits gained. Input from a therapist in designing and monitoring the programme is critical.

Abstract: Stand-up paddle boarding (SUP) is a rapidly growing sport and recreational activity for which only anecdotal evidence exists on its proposed health, fitness, and injury-rehabilitation benefits. Participants: 10 internationally and nationally ranked elite SUP athletes. Participants were assessed for their maximal aerobic power on an ergometer in a laboratory and compared with other water-based athletes. Field-based assessments were subsequently performed using a portable gas-analysis system, and a correlation between the 2 measures was performed. Maximal aerobic power (relative) was significantly higher ( P = .037) when measured in the field with a portable gas-analysis system (45.48 ± 6.96 mL · kg −1 · min −1 ) than with laboratory-based metabolic-cart measurements (43.20 ± 6.67 mL · kg −1 · min −1 ). There was a strong, positive correlation ( r = .907) between laboratory and field maximal aerobic power results. Significantly higher ( P = .000) measures of SUP paddling speed were found in the field than with the laboratory ergometer (+42.39%). There were no significant differences in maximal heart rate between the laboratory and field settings ( P = .576). The results demonstrate the maximal aerobic power representative of internationally and nationally ranked SUP athletes and show that SUP athletes can be assessed for maximal aerobic power in the laboratory with high correlation to field-based measures. The field-based portable gas-analysis unit has a tendency to consistently measure higher oxygen consumption. Elite SUP athletes display aerobic power outputs similar to those of other upper-limb-dominant elite water-based athletes (surfing, dragon-boat racing, and canoeing).

Abstract: Conservative interventions for addressing prenatal and postnatal ailments have been described in the research literature. Research results indicated that maternity support belts assist with reducing pain and other symptoms in these phases however, compliance in wearing maternity support belts is poor. To combat poor compliance, commercial manufacturers designed dynamic elastomeric fabric orthoses (DEFO)/compression garments that target prenatal and postnatal ailments. This systematic review aimed to identify, critically appraise, and synthesize key findings on the effectiveness, the feasibility, and the acceptability of using DEFO to manage ailments during pre-natal and postnatal phases of care. Electronic databases were systematically searched to identify relevant studies, resulting in 17 studies that met the eligibility criteria. There were variations in DEFO descriptors, including hosiery, support belts, abdominal binders and more, making it difficult to compare findings from the research articles regarding value of DEFO during prenatal and/or postnatal phases. A meta-synthesis of empirical research findings suggests wearing DEFOs during pregnancy has a significant desirable effect for managing pain and improving functional capacity. Further research is required to investigate the use of DEFOs for managing pain in the postnatal period and improving quality life during prenatal and postnatal care.

Abstract: At present, there is an insufficient evidence base to evaluate the effectiveness of physiotherapy following total hip replacement (THR). This study evaluated the effectiveness of a physiotherapy-supervised functional exercise programme between 12 and 18 weeks following THR. These time-points coincide with increased functional demand in patients. Adequately powered assessor-blinded randomised controlled trial. Patients were recruited at a pre-operative assessment clinic and randomised following surgery. Sixty-three subjects were randomised to either the usual care group (control, n=31) or the functional exercise+usual care group (n=32). Patients in the functional exercise group attended a physiotherapy-supervised functional exercise class twice weekly from 12 to 18 weeks following THR. Patients in the control group followed the usual care protocol with no exercise intervention. The main outcome measurement tool was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire, and the secondary outcomes included walking speed, hip abduction dynamometry, Short Form 12 physical and mental health scores, and visual analogue pain scale score. At 18 weeks post surgery, WOMAC function and walking speed improved significantly more in the functional exercise group [mean difference -4.0, 95% confidence interval (CI) -7.0 to 1.0 (P<0.01) mean difference 21.9m, 95% CI 0.60 to 43.3 (P<0.04)] than the control group, but there was no significant difference in hip abductor strength. This study demonstrated that patients who undertake a physiotherapy-led functional exercise programme between 12 and 18 weeks after THR may gain significant functional improvement compared with patients receiving usual care.

Abstract: Understanding the force profile of an exercise increases clinical confidence when assessing the benefits and potential risks of a prescribed exercise. This exploratory study presents the force profile of the hardstyle kettlebell swing in novice older adults and compares peak force with kettlebell deadlifts. These data will help inform healthcare providers and coaches who are considering prescribing kettlebell exercises for older adults. Thirty-five community-dwelling males and females (59-79 years) were recruited, from applicants to participate in the BELL trial. Two-handed hardstyle swings were performed with 8-16 kg. Deadlifts were performed with 8-24 kg and 8-32 kg for females and males, respectively. Ground reaction force was obtained from a floor-mounted force platform. Pairwise comparisons of peak force, forward force, rate of force development, swing cadence, sex, and kettlebell mass, were investigated for the kettlebell swing, with representative force-time curves described. Pairwise comparisons of peak force, sex and kettlebell mass were investigated for the deadlift, with comparisons of peak force, kettlebell mass, and sex, between swings and deadlifts. For kettlebells up to 16 kg, paired s les T-tests show a large exercise effect (δ 1.4) with peak force higher for swings than deadlifts. Data shows: (i) higher peak force during swings than deadlifts (δ = 1.77), reaching 4.5 (1.0) N.kg -1 , (ii) peak force during an 8 kg swing was greater than a 32kg deadlift, (iii) negligible difference in normalised peak force between males and females performing kettlebell swings, but a moderately large effect size during deadlifts (males females, δ = 0.69), (iv) mean rate of force development of 19.9 (4.7) N.s -1 .kg -1 with a very weak, positive correlation with kettlebell mass ( y = 14.4 + 0.32 x ), and trivial effect of sex, (v) mean forward force equal to 5.5% of vertical force during swings, increasing from 3.8 (1.6) % with 8 kg to 7.1 (2.6) % with 16 kg. During kettlebell swings, there is negligible difference in normalised net peak force between novice males and females using the same absolute loads. Where ground reaction force is a therapeutic target, kettlebell swings with an 8 kg kettlebell could have similar effects to much heavier deadlifts ( kg). Kettlebell swings performed with lighter loads, could provider similar therapeutic value to much heavier deadlifts, and may be a more appealing, affordable, and convenient option for older adults.

Abstract: The effects of hardstyle kettlebell training are increasingly cited in strength and conditioning research, yet reference data from a proficient swing is scarce. The aim of this exploratory study was to investigate the force profile of a two-handed hardstyle swing performed by a Russian Kettlebell Challenge (RKC) instructor. The subject is a 44-year-old male, body mass 75.6 kg, height 173.5 cm, with six years of regular hardstyle training experience. Two-handed hardstyle swings were performed with a series of incremental mass kettlebells (8-68 kg). Ground reaction force (GRFs) was obtained from a floor-mounted force platform. Force-time curves (FTCs), peak force, forward force, rate of force development (RFD) and swing cadence were investigated. Data revealed the FTC of a proficient swing is highly consistent and dominated by a single force peak (mean SD = 47 N), with a profile that remained largely unchanged to 24 kg. Pearson correlation analysis revealed a very strong positive correlation in peak force with kettlebell mass ( r = 0.95), which increased disproportionately from the lightest to heaviest kettlebells net peak force increased from 8.36 ± 0.75 N.kg -1 (0.85 × BW) to 12.82 ± 0.39 N.kg -1 (1.3× BW). There was a strong negative correlation between RFD and kettlebell mass ( r = 0.82) that decreased from 39.2 N.s -1 .kg -1 to 21.5 N.s -1 .kg -1 . There was a very strong positive correlation in forward ground reaction force with kettlebell mass ( r = 0.99), expressed as a ratio of vertical ground reaction, that increased from 0.092 (9.2%) to 0.205 (20.5%). Swing cadence exceeded 40 swings per minute (SPM) with all kettlebells. Our findings challenge some of the popular beliefs of the hardstyle kettlebell swing. Consistent with hardstyle practice, and previous kinematic analysis of expert and novice, force-time curves show a characteristic single large force peak, differentiating passive from active shoulder flexion. Ground reaction force did not increase proportionate to kettlebell mass, with a magnitude of forward force smaller than described in practice. These results could be useful for coaches and trainers wanting to improve athletic performance, and healthcare providers using the kettlebell swing for therapeutic purposes. Findings from this study were used to inform the BELL Trial, a pragmatic controlled trial of kettlebell training with older adults. www.anzctr.org.au ACTRN12619001177145.

Abstract: Thoracic mobility in the sagittal and horizontal planes are key requirements in the sport of surfing however to date the normal values of these movements have not yet been quantified in a surfing population. To develop a reliable method to quantify thoracic mobility in the sagittal plane to assess the reliability of an existing thoracic rotation method, and quantify thoracic mobility in an elite male surfing population. Clinical Measurement, reliability and comparative study. A total of 30 subjects were used to determine the reliability component. 15 elite surfers were used as part of a comparative analysis with age and gender matched controls. Intraclass correlation coefficient values ranged between 0.95-0.99 (95% CI 0.89-0.99) for both thoracic methods. The elite surfing group had significantly (p ≤ 0.05) greater rotation than the comparative group (mean rotation 63.57° versus 40.80°, respectively). This study has illustrated reliable methods to assess the thoracic spine in the sagittal plane and thoracic rotation. It has also quantified ROM in a surfing cohort identifying thoracic rotation as a key movement. This information may provide clinicians, coaches and athletic trainers with imperative information regarding the importance of maintaining adequate thoracic rotation.

Abstract: To clarify the efficacy and detrimental effects of orthoses used to maintain finger extension following surgical release of Dupuytren contracture. We conducted a single-center, randomized, controlled trial to investigate the effect of night extension orthoses on finger range of motion and hand function for 3 months following surgical release of Dupuytren contracture. We also wanted to determine how well finger extension was maintained in the total s le. We randomized 56 patients to receive a night extension orthosis plus hand therapy (n = 26) or hand therapy alone (n = 30). The primary outcome was total active extension of the operated fingers (°). Secondary outcomes were total active flexion of the operated fingers (°), active distal palmar crease (cm), grip strength (kg), and self-reported hand function using the Disabilities of the Arm, Shoulder, and Hand questionnaire (0-100 scale). There were no statistically significant differences between the no-orthosis and orthosis groups for total active extension or for any of the secondary outcomes. Between the first postoperative measure and 3 months after surgery, 62% of little fingers had maintained or improved total active extension. The use of a night extension orthosis in combination with standard hand therapy has no greater effect on maintaining finger extension than hand therapy alone in the 3 months following surgical release of Dupuytren contracture. Our results indicate that the practice of providing every patient with a night extension orthosis following surgical release of Dupuytren contracture may not be justified except for cases in which extension loss occurs after surgery. Our results also challenge clinicians to research ways of maintaining finger extension in a greater number of patients.

Abstract: Controlled laboratory study using a single-group, within-subjects comparison. To determine whether different types of neural mobilization exercises are associated with differing amounts of longitudinal sciatic nerve excursion measured in vivo at the posterior midthigh region. Recent research focusing on the upper limb of healthy subjects has shown that nerve excursion differs significantly between different types of neural mobilization exercises. This has not been examined in the lower limb. It is important to initially examine the influence of neural mobilization on peripheral nerve excursion in healthy people to identify peripheral nerve excursion impairments under conditions in which nerve excursion may be compromised. High-resolution ultrasound imaging was used to assess sciatic nerve excursion at the posterior midthigh region. Four different neural mobilization exercises were performed in 31 healthy participants. These neural mobilization exercises used combinations of knee extension and cervical spine flexion and extension. Frame-by-frame cross-correlation analysis of the ultrasound images was used to calculate nerve excursion. A repeated-measures analysis of variance and isolated means comparisons were used for data analysis. Different neural mobilization exercises induced significantly different amounts of sciatic nerve excursion at the posterior midthigh region (P<.001). The slider exercise, consisting of the participant performing simultaneous cervical spine and knee extension, resulted in the largest amount of sciatic nerve excursion (mean ± SD, 3.2 ± 2.0 mm). The amount of excursion during the slider exercise was slightly greater (mean ± SD, 2.6 ± 1.5 mm P = .002) than it was during the tensioner exercise (simultaneous cervical spine flexion and knee extension). The single-joint neck flexion exercise resulted in the least amount of sciatic nerve excursion at the posterior midthigh (mean ± SD, -0.1 ± 0.1 mm), which was significantly smaller than the other 3 exercises (P<.001). These findings are consistent with the results of previous research that has examined median nerve excursion associated with different neural mobilization exercises. Such nerve excursion supports theories of nerve motion associated with cervical spine and extremity movement, as generalizable to the lower limb.

Abstract: Ankle–foot orthoses (AFOs) and sensomotoric orthoses (SMotOs) are two—clinically relevant, yet under researched—types of lower limb orthoses used in children with cerebral palsy (CP). Quality of life is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Evaluating the effect of these two types of orthoses on quality of life in children with CP has not been reported on. The aim of this case study series was to synthesise and enrich the volume of evidence reported to inform real world applications of SMotO use in children with CP. Participants recruited were children with CP who performed the Berg Balance Scale, Timed Up-and-Go, the Gross Motor Function Measure and/or the Edinburgh Visual Gait Score in AFOs, SMotOs and barefoot where able. Qualitative data included videos of gait, a questionnaire and pedographs. Eight participants completed 39 quantitative and six qualitative measures, with the Edinburgh Visual Gait Score (EVGS) reporting the highest response. A general improvement was seen in gross motor skills and gait when wearing the SMotOs compared to AFOs and some parents reported that SMotOs were preferred. The reader is able to correlate the quantitative results with the qualitative evidence presented.

Abstract: Despite the routine use of physical therapy in the immediate and early postoperative phase for patients who undergo total knee replacement (TKR), there is a paucity of research into the optimal exercise protocols in both the acute inpatient setting and early period after discharge. Pedaling has often been recommended by clinicians after TKR for rehabilitation, but to our knowledge, there has been no investigation into its utility in the acute postoperative setting. Therefore, we performed a randomized controlled trial evaluating the efficacy of pedaling in the acute postoperative period. Sixty TKR patients were randomized to receive postoperative physical therapy involving either a 3-exercise pedaling (pedaling-based) or 10-exercise, non-pedaling (multi-exercise) protocol. Outcomes were assessed at 2 days, 2 weeks, and 4 months, and included physical tests of function, patient-reported outcomes, and other perioperative measures. With respect to the primary outcome, the 6-minute walk test (6MWT), the measured distance was significantly greater in the pedaling-based group than in the multi-exercise group at 2 days postoperatively (mean difference, 66 m p = 0.001). Results of other functional tests, the 10-m walk test (10MWT) and the Timed Up & Go (TUG) test, were both significantly superior for the 3-exercise pedaling group at 2 days (p = 0.016 for 10MWT, and p = 0.020 for TUG), as was the patient-reported Oxford Knee Score (p = 0.034). The latter continued to be superior at 2 weeks (p = 0.007), as was the EQ-5D score (p = 0.037). The visual analogue scale (VAS) component of the EQ-5D was significantly better for the pedaling group at all time points assessed. Length of stay was also significantly shorter, by a half-day, for the pedaling-based group (median of 2.5 days compared with 3.0 days for the multi-exercise group p = 0.024). The multi-exercise protocol was not superior for any outcome measure at any time point. A pedaling-based protocol in the immediate postoperative period after TKR was superior to a standard multi-exercise protocol in both functional and patient-reported outcomes, with these benefits decreasing over time.

Abstract: As swimming and surfing are prone dominant sports, it would be more sport specific to assess shoulder active range of motion in this position. To determine the reliability of the inclinometer and HALO© for assessing shoulder active range of motion in supine and prone and the concurrent validity of the HALO©. Concurrent validity is based on the comparison of the HALO© and inclinometer. To determine if active range of motion (AROM) differences exists between prone and supine when assessing shoulder internal (IR) and external rotation (ER). The design included clinical measurement, reliability and validity. Thirty shoulders (mean age = 26.8 years) without pathology were evaluated. Measurements were taken in supine and prone with both an inclinometer and HALO© device. Active ER ROM in prone was significantly higher than in supine when using both devices. Intra-rater reliability (within and between session) intraclass correlation coefficient (ICC) values ranged between 0.82-0.99 for both devices in supine and prone. An ICC test revealed a significant (p < 0.01) correlation for both devices in IR and ER movements (ICC3,1 = 0.87 and ICC3,1 = 0.72), respectively. This study has shown prone assessment of active ER and IR ROM to be a reliable and appropriate method for prone dominant athletes (swimmers and surfers). In this study greater ER ROM was achieved in prone compared to supine. This finding highlights the importance of standardizing the test position for initial and follow up assessments.

Abstract: This study aimed to (a) identify factors that motivate older adults to participate in aqua-based exercise (b) identify potential barriers and (c) compare perceptions between older adults with and without osteoarthritis (OA). Fifteen adults above 60 years of age participated in one of three focus groups during which they discussed perceived benefits, motives, and barriers to aqua exercise. Pain reduction was considered a major benefit among those with OA, improved health and fitness was a principal benefit for those without OA. All participants felt that the instructor could act as both a motivator and barrier the most significant barrier was cold changing facilities in winter. With the exception of pain reduction, perceived benefits, motivators, and barriers to aqua-based exercise are similar among older adults with and without OA. A greater understanding of these factors may help us to facilitate older adults with OA to initiate and adhere to aqua-based exercise.

Abstract: Purpose: To explore the influence of education and other factors on an athlete& rsquo s decision to return to sport post-concussion injury, and whether general risk-taking tendencies are related to return to sport post-concussion decisions in these athletes. Participants and Methods: A self-administered electronic survey was designed to examine their decision-making process when faced with scenario-based questions regarding returning to sport post-concussion injury. Students from the Health Sciences and Medicine Faculty at Bond University were invited to participate. Participants were allocated to a concussion education or non-education group prior to commencement of questionnaire via the random generator on Qualtrics software function. The risk propensity scale was used to assess the risk aversion of each participant. Results: Sixteen respondents were randomized evenly to education and non-education groups. Seven (43.8%) had previously received concussion education training prior to completing the questionnaire, with one (14%) choosing to return to sport in the scenario-based questions. The education group reported two (25%) respondents return to sport, while three (75%) respondents out of four returned to sport with no education or previous concussion training. Influential factors that impacted the decision whether to return to sport or not included: game importance, concussion severity and symptoms, and various internal and external factors. Finally, there was a ergence in results from the risk propensity scale when deciding to return to sport and general risk-taking propensities. Conclusion: This study identified several influential factors including game importance, concussion severity and symptoms which play a significant role in the return to sport decisions post-concussion injury.

Abstract: To determine if lower extremity functional tests are reliable and valid screening tests of lower extremity dynamic alignment in healthy young athletes. Quantitative experimental test-re-test. Peak three-dimensional pelvis and lower extremity kinematics were quantified in 23 uninjured young athletes (11 ± 1 years) during three lower extremity functional tests (Small Knee Bend [SKB], Single Leg SKB and Drop Jump) and Running. A nine camera motion analysis system captured three trials of all tests. All functional tests were repeated by 10 young athletes eight to ten weeks later. Visual 3D and Labview were used to process all data. Intraclass correlation coefficients (ICC) and typical errors (TE) were used to assess within- and between-day reliability of all variables. Pearson correlation coefficients were used to evaluate associations between peak kinematics during the SKB and Drop Jump and between the Single Leg SKB and Running. Within-day reliability was excellent (ICC ≥ 0.85) and between-day reliability was excellent to good (ICC range 0.60-0.92) for the majority of kinematic variables. Correlations for peak lower extremity kinematics between SKB and Drop Jump were moderate to very large (r = 0.39-0.87) as were correlations between Single Leg SKB and Running (r = 0.45-0.84). Kinematics during the SKB and single leg SKB have moderate to high reliability and are similar to those during a drop jump or running.

Abstract: Ultrasound imaging allows cost effective in vivo analysis for quantifying peripheral nerve excursion. This study used ultrasound imaging to quantify longitudinal radial nerve excursion during various active and passive wrist movements in healthy participants. Frame-by-frame cross-correlation software allowed calculation of nerve excursion from video sequences. The reliability of ultrasound measurement of longitudinal radial nerve excursion was moderate to high (intraclass correlation coefficient range = 0.63-0.86, standard error of measurement 0.19-0.48). Radial nerve excursion ranged from 0.41 to 4.03 mm induced by wrist flexion and 0.28 to 2.91 mm induced by wrist ulnar deviation. No significant difference was seen in radial nerve excursion during either wrist movement (p > 0.05). Wrist movements performed in forearm supination produced larger overall nerve excursion (1.41 ± 0.32 mm) compared with those performed in forearm pronation (1.06 ± 0.31 mm) (p < 0.01). Real-time ultrasound is a reliable, cost-effective, in vivo method for analysis of radial nerve excursion.

Abstract: To investigate the within-day and between-day reliability of 3D lower extremity kinematics during five lower extremity functional screening tests and to assess the association between these kinematics and those recorded during jogging. Peak three-dimensional lower extremity kinematics were quantified in 25 uninjured participants during five lower extremity functional tests and jogging. A nine camera motion analysis system (Qualysis Medical AB, Sweden) was used to capture three trials of all tests. All functional tests were repeated by 10 participants one to two days later. Visual 3D (C-Motion Inc, USA) and Labview were used to process all data. Intraclass correlation coefficients (ICC) and typical errors (TE) were used to assess within- and between-day reliability of all variables. Pearson correlation coefficients were used to evaluate the association between peak joint kinematics during the functional tests and jogging. For the majority of kinematic variables the within-day reliability was excellent (ICC ≥ 0.92) and the between-day reliability was excellent to good (ICC ≥ 0.80). The correlation between kinematics of the functional tests and jogging was generally large to very large (r = 0.53 to 0.93). These results suggest these lower extremity functional screening tests should prove a useful clinical tool when assessing dynamic lower extremity alignment.

Abstract: Child obesity is associated with poor health and reduced motor skills. This study aimed to assess the diagnostic accuracy of the KidFit Screening Tool for identifying children with overweight/obesity, reduced motor skills and reduced cardiorespiratory fitness. Fifty-seven children (mean age: 12.57 ± 1.82 years male/female: 34/23) were analysed. The Speed and Agility Motor Screen (SAMS) and the Modified Shuttle Test-Paeds (MSTP) made up the KidFit Screening Tool. Motor Proficiency (BOT2) (Total and Gross) was also measured. BMI, peak-oxygen-uptake (VO2peak) were measured with a representative sub-s le (n = 25). Strong relationships existed between the independent variables included in the KidFit Screening Tool and BMI (R2 = 0.779, p 0.001) Gross Motor Proficiency (R2 = 0.612, p 0.001) and VO2peak (mL/kg/min) (R2 = 0.754, p 0.001). The KidFit Screening Tool has a correct classification rate of 0.84 for overweight/obesity, 0.77 for motor proficiency and 0.88 for cardiorespiratory fitness. The sensitivity and specificity of the KidFit Screening Tool for identifying children with overweight/obesity was 100% (SE = 0.00) and 78.95%, respectively (SE = 0.09), motor skills in the lowest quartile was 90% (SE = 0.095) and 74.47% (SE = 0.064), respectively, and poor cardiorespiratory fitness was 100% (SE = 0.00) and 82.35% (SE = 0.093), respectively. The KidFit Screening Tool has a strong relationship with health- and performance-related fitness, is accurate for identifying children with health- and performance-related fitness impairments and may assist in informing referral decisions for detailed clinical investigations.

Abstract: Identify predictor variables and models for clinical outcomes for primary care shoulder pain patients to 12 months follow-up. A non-randomized audit with measures of pain and disability at 3 weeks, 3, 6 and 12 months. Of 208 patients, 161 agreed to participate with 96.9, 98.1, 87.0 and 83.9% follow-up at 3 weeks, 3, 6 and 12 months respectively. Treatment consisted of exercise and manual therapy-based physiotherapy and corticosteroid injection under specified selection criteria. Potentially useful baseline variables were evaluated in univariate logistic regressions with the dependent variables determined by SPADI Questionnaire at 3 weeks, 3, 6 and 12 months. Variables associated (p-value ≤ 0.2) were retained for potential inclusion within multiple logistic regression analyses. Pain not improved by rest, intermittent pain, lower pain intensity with physical tests and absence of subacromial bursa pathology on ultrasound at the 3-week follow-up, constant pain and lower pain intensity with physical tests are predictors of excellent outcomes at the 3-month follow- up. Worse baseline pain and disability, no history of asthma, pain better with rest, better physical functioning, greater fear avoidance, male gender, no history of pain in the opposite shoulder, pain referred below the elbow, sleep disturbed by pain, smaller waist circumference, lower pain intensity with physical tests are factors predictive of excellent outcomes at the 12-month follow-up. Only higher pain intensity with physical tests was associated with a poor clinical outcome. Predictive models for clinical outcomes in primary-care patients with shoulder pain were achieved for excellent clinical outcomes, successfully classifying 70-90% of cases.

Abstract: To compare the accuracy of combinations of clinical examination findings for predicting a positive response to injection of local anaesthetic into the subacromial bursa. Prospective, cohort, diagnostic validity design. Consecutive patients with shoulder pain recruited from primary care physiotherapy and general medical practices. All subjects underwent a standardised clinical examination (index test) followed by a diagnostic injection of xylocaineTM into the subacromial bursa (reference standard test) performed under ultrasound guidance. Clinical examination variables associated with a positive anaesthetic response (≥ 80% post-injection reduction in pain intensity) were identified (p < 0.20) and diagnostic accuracy was calculated. Of the 196 subjects who received a subacromial bursa injection, 66 subjects (34%) reported a positive anaesthetic response. Strain injury (adjusted odds ratio (AOR) 2.3), anterior shoulder pain (AOR 2.3) and absence of pain with external rotation at 90º abduction (AOR 3.9) were the strongest clinical predictors of positive anaesthetic response. Clinical prediction model variables demonstrated 100% specificity (3 positive tests) but low sensitivity (maximum 40%) for a positive anaesthetic response. Combinations of 9 other clinical variables also demonstrated 100% specificity (7 or more positive tests), and improved sensitivity (95 to 100%) for a PAR compared with clinical prediction model variables when less than two findings were present. Combinations of these clinical tests may assist the clinician to differentiate subacromial pain from other shoulder conditions and guide selection of targeted pain management interventions. Additional diagnostic tests may be required when clinical criteria are not satisfied.
