Abstract: Study Design Systematic review. Background Despite improvements in self-reported symptoms and perceived functional ability after total hip arthroplasty (THA) and total knee arthroplasty (TKA), it is unclear whether changes in objectively measured physical activity (PA) occur after surgery. Objective To determine if objectively measured PA increases after THA and TKA in adults with osteoarthritis. Methods Five electronic databases were searched from inception to March 3, 2015. All study designs objectively measuring PA before and after THA or TKA were eligible, including randomized controlled trials, cohort studies, and case-control studies. Two reviewers independently screened abstracts and full texts and extracted study demographic, PA, and clinical outcome data. Standardized mean differences (SMDs) and 95% confidence intervals were calculated for accelerometer- and pedometer-derived estimates of PA. Risk of methodological bias was assessed with Critical Appraisal Skills Programme checklists. Results Eight studies with a total of 373 participants (238 TKA, 135 THA) were included. Findings were mixed regarding improvement in objectively measured PA at 6 months after THA (SMDs, -0.20 to 1.80) and TKA (SMDs, -0.36 to 0.63). Larger improvements from 2 studies at 1 year postsurgery were generally observed after THA (SMDs, 0.39 to 0.79) and TKA (SMDs, 0.10 to 0.85). However, at 1 year, PA levels were still considerably lower than those of healthy controls (THA SMDs, -0.25 to -0.77 TKA SMDs, -1.46 to -1.80). Risk-of-bias scores ranged from 3 to 9 out of 11 (27%-82%) for cohort studies, and from 3 to 8 out of 10 (30%-80%) for case-control studies. Conclusion The best available evidence indicates negligible changes in PA at 6 months after THA or TKA, with limited evidence for larger changes at 1 year after surgery. In the 4 studies that reported control-group data, postoperative PA levels were still considerably less than those of healthy controls. Improved perioperative strategies to instill behavioral change are required to narrow the gap between patient-perceived functional improvement and the actual amount of PA undertaken after THA and TKA.

Abstract: Background. To influence adolescent health, a greater understanding of time use and covariates such as gender is required. Purpose. To explore gender-specific time use patterns in Australian adolescents using high-resolution time use data. Method. This study analyzed 24-hour recall time use data collected as part of the 2007 Australian National Children’s Nutrition and Physical Activity Survey ( n = 2,200). Univariate analyses to determine gender differences in time use were conducted. Results. Boys spent more ( p .0001) time participating in screen-based (17.7 % vs. 14.2% daily time) and physical activities (10.7% vs. 9.2%). Girls spent more ( p .0001) time being social (4.7% vs. 3.4% daily time), studying (2.0% vs. 1.7%), and doing household chores (4.7% vs. 3.4%). Conclusions. There are gender-specific differences in time use behavior among Australian adolescents. The results reinforce existing time use gender-based stereotypes. Implications. The gender-specific time use behaviors offer intervention design possibilities.

Abstract: Objectives. Despite the incidence of joint replacements in Australia, there is a paucity of information regarding how patients progress from their referral to their surgery. The aim of this study was to describe a patient pathway from referral to receipt of total hip replacement (THR) or total knee replacement (TKR) surgery in South Australian public hospitals. Methods. Patient perspectives of the pathway to THR and TKR surgery were obtained via a postal survey (n = 450) and hospital employee perspectives were attained via semi-structured interviews (n = 19). Survey data were analysed using descriptive statistics and interview data were analysed thematically. Results. A typical patient pathway to THR and TKR surgery can be ided into two distinct phases referral-to-initial appointment (9–24 months), and initial appointment-to-surgery (12–15 months). This gives an overall waiting period between 2 and 3 years for THR or TKR surgery. Conclusions. Waiting times for THR and TKR surgery reported in this study were longer than other reports in the literature. Current Australian health policy does not consider the first (and longest) phase of the patient pathway. Excluding this initial phase could be generating an erroneous perception of the patient pathway to THR or TKR surgery, possibly leading to poorly considered health reforms. What is known about the topic? Meeting the demand for elective surgery services in public hospitals is an ongoing challenge for governments and health systems alike. The persistent mismatch between supply and demand has resulted in the development of waiting lists for elective total hip replacement (THR) and total knee (TKR) replacement surgery in Australia. Current state-level health policies such as the Policy Framework and Associated Procedural Guidelines for Elective Surgery Services in South Australia or the Elective Surgery Access Policy in Victoria, outline a generic pathway consisting of a few linear steps that occur immediately before receipt of surgery, without consideration of the early stages of the journey. Aside from these types of policies, we were unable to identify any published literature outlining the patient journey from referral to receipt of THR or TKR surgery. As such, our understanding of the issue is inadequate due the paucity of existing research evidence. What does this paper add? Our current understanding of the patient journey to THR and TKR surgery is limited to the perspective of the policy-makers, whose focus is the organisation of waiting lists and the systematic progression of an in idual through the elective surgery system. This perspective reinforces the assumption that it is a simple, linear process and may lead to erroneous judgements regarding the impact that the patient pathway has on an in idual and the time it takes to progress along that pathway. This study presents the patient pathway from the perspective of in iduals working within the systems responsible for delivering THR and TKR surgery and from patients who have received a joint replacement in a South Australian public hospital. As such, this paper provides new insight into the length, impact and features of the entire patient journey, rather than a snap-shot of the final stages. What are the implications for practitioners? This study is the first step towards better understanding of the patient pathway to joint replacement surgery in Australian public hospitals. Greater understanding of the complete pathway and identification of areas of congestion within the pathway, as evidenced by longer waiting periods, offers insight into areas with the potential for effective reforms. Should the patient pathway be significantly altered, the experience of practitioners responsible for the interim and postoperative management of patients undergoing THR and TKR surgery will also be changed. Additionally, practitioners currently frustrated by the long delays experienced by their patients who are in need of elective surgery in Australian public hospitals, could have that frustration abated by system improvements that reduce the length and complexity of the pathway to joint replacement surgery.

Abstract: There is good evidence in the literature supporting physiotherapy in the management of some forms of headache. Dry needling of myofascial trigger points is becoming an increasingly common approach despite a paucity of research evidence supporting its use. The purpose of this review was to determine the evidence supporting the use of dry needling in addition to conventional physiotherapy in the management of tension-type and cervicogenic headache. Ten databases were searched for evidence of the effect of dry needling on the severity and frequency of tension and cervicogenic headache based ICHD classifications. Three relevant studies were identified and all three showed statistically significant improvements following dry needling, but no significant differences between groups. Only one study reported on headache frequency or intensity, reporting a 45 mm improvement in VAS score following the addition of dry needling to conventional physiotherapy. Two studies showed significant improvements with dry needling over 4–5 weeks of treatment. No adverse events were reported. The literature suggests that while there is insufficient evidence to strongly advocate for the use of dry needling, it may be a useful addition to conventional physiotherapy in headache management. Further research with a stronger methodological design is required.

Abstract: Objective South Australia is taking an innovative step in transforming the way its healthcare is organised and delivered to better manage current and future demands on the health system. In an environment of transforming health services, there are clear opportunities for allied health to assist in determining solutions to various healthcare challenges. A recent opinion piece proposed 10 clinician-driven strategies to assist in maximising value and sustainability of healthcare in Australia. The present study aimed to seek the perspectives of allied health clinicians, educators, researchers, policy makers and managers on these strategies and their relevance to allied health. Methods A survey of allied health practitioners was undertaken to capture their perspectives on the 10 clinician-driven strategies for maximising value and sustainability of healthcare in Australia. Survey findings were then layered with evidence from the literature. Results Highly relevant across allied health are the strategies of discontinuation of low value practices, targeting clinical interventions to those getting greatest benefit, active involvement of patients in shared decision making and self-management and advocating for integrated systems of care. Conclusions Allied health professionals have been involved in the South Australian healthcare system for a prolonged period, but their services are poorly recognised, often overlooked and not greatly supported in existing traditional practices. The results of the present study highlight ways in which healthcare services can implement strategies not only to improve the quality of patient outcomes, but also to offer innovative solutions for future, sustainable healthcare. The findings call for concerted efforts to increase the utilisation of allied health services to ensure the ‘maximum value for spend’ of the increasingly scarce health dollar. What is known about the topic? In medicine, clinician-driven strategies have been proposed to minimise inappropriate and costly care and maximise highly appropriate and less expensive care. These strategies were developed based on clinical experiences and with supporting evidence from scientific studies. What does this paper add? Major changes to the health system are required to slow down the growth in healthcare expenditure. This paper describes opportunities in which allied health practitioners can implement similar strategies not only to improve the quality of patient outcomes, but also to offer cost-effective solutions for a sustainable healthcare. What are the implications for practitioners? Allied health practitioners can provide solutions to healthcare challenges and assist in the transformation of healthcare in Australia. However, for this to happen, there should be concerted efforts to increase recognition of and support for the use of allied health services.

Abstract: Complex physical interventions are widely used in physiotherapy, despite doubts over the validity of clinical trial results due to lack of credible shams. Credible shams are critically needed, so too, therefore, is a process by which they can be developed. The authors used a novel methodology to develop and test blinding protocols for dry needling, a complex physical intervention for which blinding is particularly difficult. The research design was a practical three-day workshop influenced by Participatory Action Research, which uses iteration and reflection to solve a problem. Five multidisciplinary experts (researchers, clinicians, technician, magician) were invited. Healthy volunteers ('recipients', n=17) and accredited physiotherapists (n=6) were recruited to enable testing of blinding strategies. Primary outcomes were expert opinion on the potential to blind recipients/therapists for (1) in idual blinding strategies, and (2) entire blinding protocols. Secondary outcomes included recipient/therapist blinding effectiveness and acceptability. Experts iteratively developed 11 blinding protocols involving 22 blinding strategies. Experts rated 18 of the blinding strategies to 'definitely have potential' and identified four categories: knowledge of the sham, clinical interaction, disinformation, and sensation. Recipient and therapist blinding became more successful as the protocols evolved. Credible shams capable of simultaneous recipient and therapist blinding have been regarded to be impossible in dry needling. The preliminary success of the devised protocols suggest that our novel approach may be a crucial step in sham development. Improvements in expert rankings and blinding effectiveness as the protocols progressed support the value of this workshop approach.

Abstract: The way an in idual uses one’s time can greatly affect his or her health. The purpose of this article was to examine the cross-sectional cross-elasticity relationships for use of time domains in a s le of Australian adolescents. This study analyzed 24-hour recall time use data collected using the Multimedia Activity Recall for Children and Adults ( N = 2,200). Using simple linear regression, the authors calculated the difference in time devoted to a reference activity (i.e., screen time, sleep, or social) given 1 hour extra in the time devoted to a criterion activity (i.e., physical activity). The most elastic activities were screen time and school-related time. Every additional hour committed to physical activity was associated with 32 minutes less screen time. This relationship was more pronounced in obese adolescents (−56 minutes screen time) compared with normal (−31 minutes) and overweight (−27 minutes) adolescents. Promising behavior patterns exist, with screen time appearing as a highly elastic behavior.

Abstract: Dry needling is widely used in physiotherapy. Lack of blinding in clinical trials means that dry needling effects and mechanisms remain unclear, with blinding issues accepted as an unavoidable barrier to better evidence. The authors aimed to overcome this barrier by designing a protocol to double-blind dry needling trials. A prospectively registered randomised experiment tested a novel blinding protocol for blinding effectiveness. University physiotherapy clinic. Therapists (n=15) and asymptomatic volunteers ('recipients') (n=45) were randomly allocated to real and/or sham interventions. The protocol involved custom-made needles and cognitive and multisensory blinding techniques. The primary outcome was guesses about allocation. The a priori criterion for successful blinding was ≤50% correct guesses (random chance). Secondary analyses explored blinding patterns using blinding indices. Correct guesses were not different from 50% for therapists [41% (95%CI 30 to 50), n=120 guesses] or recipients [49% (95%CI 38 to 60), n=90 guesses]. Blinding indices supported the primary result but revealed that recipients were better at detecting real dry needling than sham. Both therapists and recipients were successfully blinded, which contrasts with the widely held assumption that double-blinding is impossible for needling interventions. The authors recommend that any future trials can, and therefore should, blind therapists. However, secondary analyses revealed that recipients receiving real dry needling were less blinded than sham recipients, which may still create bias in clinical trials and suggests further work is needed to improve recipient blinding. Nonetheless, the current findings offer an opportunity to gain better evidence concerning the effects and mechanisms of dry needling. osf.io/rkzeb/.

Abstract: Blinding of participants and therapists in trials of physical interventions is a significant and ongoing challenge. There is no widely accepted sham protocol for dry needling. The purpose of this review was to summarize the effectiveness and limitations of blinding strategies and types of shams that have been used in dry needling trials. Twelve databases were searched from inception to February 2016. Trials that compared active dry needling with a sham that simulated dry needling were included. The main domains of data extraction were participant/therapist details, intervention details, blinding strategies, blinding assessment outcomes, and key conclusions of authors. Reported blinding strategies and sham types were synthesized descriptively, with available blinding effectiveness data synthesized using a chance-corrected measurement of blinding (blinding index). The search identified 4894 in idual publications with 27 trials eligible for inclusion. In 22 trials, risk of methodological bias was high or unclear. Across trials, blinding strategies and sham types were heterogeneous. Notably, no trials attempted therapist blinding. Sham protocols have focused on participant blinding using strategies related to group standardization and simulation of tactile sensations. There has been little attention given to the other senses or cognitive strategies to enhance intervention credibility. Nonpenetrating sham types may provide effective participant blinding. Trials were clinically and methodologically erse, which limited the comparability of blinding effectiveness across trials. Reported blinding evaluations had a high risk of chance findings with power clearly achieved in only 1 trial. Evidence-based consensus on a sham protocol for dry needling is required. Recommendations provided in this review may be used to develop sham protocols so that future protocols are more consistent and potentially more effective.

Abstract: Objectives. Waiting lists for elective surgery are a persistent problem faced by health systems. The progression through elective surgery waiting lists can be likened to a game of snakes and ladders where barriers (snakes) delay access to surgery and facilitators (ladders) expedite access. The aim of the present study was to describe the barriers and facilitators to delivery of total hip- and total knee-replacement surgery in South Australian public-funded hospitals. Methods. Semistructured interviews with staff, direct observation of administrative processes and documentation analysis were combined under a systems theory framework. Results. System barriers (snakes) were grouped into five categories: resources, workload, hospital engagement, community engagement and system processes. Inadequate resources was the most prominent barrier, patient cancellations resulted in one-third of administrative tasks being repeated and there was a perceived lack of engagement to maximising efficiency. Interestingly, despite a lack of resources being perceived to be the biggest problem, additional resources without system change was not considered an effective long-term strategy. Conclusions. Given the complexity of the elective surgery system, it is not surprising that single-item reforms have not created lasting reductions in waiting times. Multifaceted, whole-system reforms may be more successful. What is known about the topic? Waiting lists and waiting times for surgery are controversial, associated with frequent reforms and negative emotive headlines. We know from existing literature and anecdotal reports that in iduals frequently experience lengthy delays before receiving elective surgery. Anecdotal reports also suggest that there are inefficiencies within elective surgery systems that contribute to these delays and result in cancellations, patient deterioration and poor overall satisfaction with the public health system in Australia. What isn’t clear is whether this perception is accurate and what inefficiencies do exist that could be specifically targeted for reform. What does this paper add? This paper adds weight to the argument that some inefficiencies exist within elective surgery systems, and identifies specific barriers to the delivery of total hip- and total knee-replacement surgery in South Australian public hospitals. It also identifies several strategies that could improve system function, some of which have already been implemented at a local level in response to stress on the system, and some of which require broad region- or state-wide change. In contrast to existing research, the level of detail provided in the present paper should allow for targeted reforms with the potential to improve system function and the efficiency with which joint-replacement surgery can be delivered. What are the implications for practitioners? All clinicians aim to provide the best intervention for their patients. Should the findings of this study be used to inform elective surgery system changes, patients and clinicians should experience a more streamlined approach to referral for and receipt of elective surgery in public hospitals. The consistency with which barriers and facilitators were identified across the four hospitals involved in this research supports the generalisability of the results. This further suggests that although specific to hip and knee replacement, many of the same barriers and facilitators could be in place across numerous surgical and non-surgical disciplines.

Abstract: A systematic literature review was conducted to identify the best available evidence describing the differences in clinical outcome associated with the different methods of total knee replacement (TKR) fixation. Randomized trials published between 1980 and January 2011 comparing differences in clinical outcome scores between groups allocated to either cemented or uncemented fixation for TKR were included. Nine of the 11 studies included in the review reported no significant differences in clinical outcomes between groups with either cemented or uncemented prosthesis components. Critical appraisal of methodological bias revealed consistent shortcomings in study design and execution. It is apparent that more rigorous studies with longer follow-up periods are required to verify which method of fixation may be preferable in enhancing clinical outcomes.

Abstract: Blinding is critical to clinical trials because it allows for separation of specific intervention effects from bias, by equalising all factors between groups except for the proposed mechanism of action. Absent or inadequate blinding in clinical trials has consistently been shown in large meta-analyses to result in overestimation of intervention effects. Blinding in dry needling trials, particularly blinding of participants and therapists, is a practical challenge therefore, specific effects of dry needling have yet to be determined. Despite this, dry needling is widely used by health practitioners internationally for the treatment of pain. This review presents the first empirical account of the influence of blinding on intervention effect estimates in dry needling trials. The aim of this systematic review was to determine whether participant beliefs about group allocation relative to actual allocation (blinding effectiveness), and/or adequacy of blinding procedures, moderated pain outcomes in dry needling trials. Twelve databases (MEDLINE, EMBASE, AMED, Scopus, CINAHL, PEDro, The Cochrane Library, Trove, ProQuest, trial registries) were searched from inception to February 2016. Trials that compared active dry needling with a sham that simulated dry needling were included. Two independent reviewers performed screening, data extraction, and critical appraisal. Available blinding effectiveness data were converted to a blinding index, a quantitative measurement of blinding, and meta-regression was used to investigate the influence of the blinding index on pain. Adequacy of blinding procedures was based on critical appraisal, and subgroup meta-analyses were used to investigate the influence of blinding adequacy on pain. Meta-analytical techniques used inverse-variance random-effects models. The search identified 4,894 in idual publications with 24 eligible for inclusion in the quantitative syntheses. In 19 trials risk of methodological bias was high or unclear. Five trials were adequately blinded, and blinding was assessed and sufficiently reported to compute the blinding index in 10 trials. There was no evidence of a moderating effect of blinding index on pain. For short-term and long-term pain assessments pooled effects for inadequately blinded trials were statistically significant in favour of active dry needling, whereas there was no evidence of a difference between active and sham groups for adequately blinded trials. The small number and size of included trials meant there was insufficient evidence to conclusively determine if a moderating effect of blinding effectiveness or adequacy existed. However, with the caveats of small s le size, generally unclear risk of bias, statistical heterogeneity, potential publication bias, and the limitations of subgroup analyses, the available evidence suggests that inadequate blinding procedures could lead to exaggerated intervention effects in dry needling trials.

Abstract: To establish the effectiveness of walking alone and walking compared to other non-pharmacological management methods to improve disability, quality of life, or function in adults with chronic low back pain. A systematic search of the following databases was undertaken: Medline, Embase, CINAHL, Scopus, Pedro, SportDiscus, Cochrane Central Register of Controlled Trials. The following keywords were used: ‘back pain’ or ‘low back pain’ or ‘chronic low back pain’ and ‘walk*’ or ‘ambulation’ or ‘treadmill*’ or ‘pedometer*’ or ‘acceleromet*’ or ‘recreational’ and ‘disability’ or ‘quality of life’ or ‘function*’. Primary research studies with an intervention focus that investigated walking as the primary intervention compared to no intervention or any other non-pharmacological method in adults with chronic low back pain (duration months). Seven randomised controlled trials involving 869 participants were included in the review. There was no evidence that walking was more effective than other management methods such as usual care, specific strength exercises, medical exercise therapy, or supervised exercise classes. One study found over-ground walking to be superior to treadmill walking, and another found internet-mediated walking to be more beneficial than non-internet-mediated walking in the short term. There is low quality evidence to suggest that walking is as effective as other non-pharmacological management methods at improving disability, function, and quality of life in adults with chronic low back pain.

Abstract: Background. The popular media infer that satisfaction with waiting lists for total hip or knee replacement surgery is poor however, there is little supporting evidence for this. The purpose of this study was to describe patients satisfaction with the service they received for joint replacement surgery in a public hospital. Methods. A cross-sectional design was used to survey 450 patients. Data was analysed descriptively and chi-squared analyses (significance level of P 0.05 ) were used to examine associations between variables. Results. The response rate was 71%. Nearly three-quarters ( n = 312 ) of the s le were “very happy” with the service and 92.0% ( n = 379 ) indicated that they would have their surgery again. Satisfaction was significantly associated with waiting time to the first appointment (chi-square P = 0.002 ), whether the patients enquired about their waiting time (chisquare P = 0.003 ), and the number of preoperative appointments (chisquare P = 0.04 ). Most participants reported a maximum acceptable waiting period for initial appointment of less than 6 months but nearly half waited longer. Conclusions. The perception that patients are unhappy with elective surgery services in Australia may be unfounded despite many waiting longer than they consider appropriate.

Abstract: In clinical trials of physical interventions, participant blinding is often poorly addressed and therapist blinding routinely omitted. This situation presents a substantial barrier to moving the field forward. Improving the success of blinding will be a vital step towards determining the true mechanisms of physical interventions. We used a Delphi approach to identify important elements of shams for physical interventions to maximise the likelihood of participant and therapist blinding in clinical trials. Two expert groups were recruited: (1) experts in research methodology and (2) experts in deceptive and/or hypnotic techniques including magic. Magicians were included because they were considered a potentially rich source of innovation for developing credible shams due to their unique skills in altering perceptions and beliefs. Three rounds of survey were conducted, commencing with an open-ended question. Responses were converted to single ‘items’, which participants rated in the following two rounds using a 9-point Likert scale, categorised as ‘Not important’ (0–3), ‘Depends’ (4–6) and ‘Essential’ (7–9). Consensus was pre-defined as ≥80% agreement within a 3-point category. Thirty-eight experts agreed to participate (research methodology: n = 22 deceptive and/or hypnotic techniques: n = 16), and 30 experts responded to at least one round (research methodology: n = 19 deceptive and/or hypnotic techniques: n = 11). Of 79 items, five reached consensus in the ‘Essential’ category in both groups, which related to beliefs of participants ( n = 3 items), interactions with researchers ( n = 1 item) and standardisation of clinical assessments ( n = 1 item). Thirteen additional items reached consensus in the ‘Essential’ category in one group. Experts in research methodology had one additional item reach consensus, related to authentic delivery of study information. The remaining 12 additional items that reached consensus in the deceptive and/or hypnotic techniques group related mainly to therapist attitude and behaviour and the clinical interaction. Experts agreed that, for shams to be believable, consideration of cognitive influences is essential. Contrary to the focus of previous shams for physical interventions, replicating the tactile sensation of the active treatment was not considered an essential part of sham development. Therefore, when designing sham-controlled clinical trials, researchers should carefully consider the cognitive credibility of the entire intervention experience, and not just the indistinguishability of the sham intervention itself. The findings provide new guidance to researchers on important contributors to blinding in physical intervention trials.
