Abstract: Pelvic girdle pain is commonly experienced during pregnancy and results in significant physical, psychosocial and work-related challenges. Few studies have investigated the lived experiences of pregnant women with pelvic girdle pain and their coping strategies. There is a need to develop a greater understanding of this prevalent condition among Australian women. Thus, this study seeks to gain information about the impact of pelvic girdle pain on daily life and how women cope with this condition during pregnancy. A qualitative research design, situated within a phenomenological framework, is adopted. The participants will be invited to describe their lived experiences of pregnancy-related pelvic girdle pain, the impact on their daily life and the strategies they use to cope with the condition. A stratified purposive s le will be undertaken to ensure the s le provides information-rich cases representative of women with pregnancy-related pelvic girdle pain. Face-to-face, in idual, semistructured interviews will be conducted with participants at Westmead Hospital, Sydney, Australia. A solicited diary will be offered to any participants who may find attending the interview difficult. All participants will also be invited to attend a focus group session. The different methods of data collection used in this study will allow for triangulation, thereby increasing the trustworthiness of findings. Ethical approval has been granted by the Human Research Ethics Committees of Westmead Hospital, Sydney, and Western Sydney University, Sydney. Dissemination of results will be via journal articles and conference presentations.

Abstract: To describe the care needs of women with pregnancy‐related pelvic girdle pain based on the Caring Life‐Course Theory. A descriptive qualitative research design. Data were collected between November 2019 and February 2021 from 20 purposively selected pregnant women with pelvic girdle pain aged between 22 and 39 years in antenatal care at a tertiary hospital in Australia. In idual semi‐structured interviews were recorded via a digital audio recorder and transcribed verbatim. Qualitative content analysis method was used to analyse the data. Five broad themes were identified: pain is an added burden to pregnancy knowledge is power to own what happens to me engaging in self‐help care from others is useful and pain deserves more attention from healthcare professionals. Caring Life‐Course Theory presented a useful and applicable scaffold for describing care needs of pregnant women with pelvic girdle pain. The study revealed experiencing pelvic girdle pain led to additional care needs during pregnancy, highlighting the importance of self‐management strategies and an appreciation of care from others to assist women in limiting the effects of the pain. Participants identified the need for more information and attention from healthcare professionals to be able to better manage their condition. This study presents a comprehensive picture of the change in care needs triggered by experiencing pelvic girdle pain during pregnancy. The findings have the potential to facilitate better care provision by considering novel methods of delivery, such as information and communication technology, whilst acknowledging the value placed on credible and trusted sources. Knowledge acquired through this study may be used by nurses and midwives, along with other healthcare professionals, to enhance the provision of comprehensive care that is acceptable to women with pelvic girdle pain during pregnancy.

Abstract: The instant at which a muscle increases its level of activity from baseline represents the onset of muscle activity. Accurate identification of muscle onset allows determination of temporal and litude characteristics of the surface electromyography (sEMG) signal. This investigation determined the intra- and inter-tester reliability for determining the onset of medial gastrocnemius (MG) activity using visual and automated methods. One hundred hop cycles, performed at 2.2Hz, were selected from sEMG recordings (bandpass filtered 50-500Hz and full wave rectified) of ten participants who performed three trials of single-leg hopping. The onset of MG muscle activity was identified by 3 separate investigators on two separate occasions and an automated method (10% of the peak activation litude). The duration of the anticipatory period, from muscle onset to initial ground contact, was then determined. Intra-tester (ICC from 0.72 to 0.95) and inter-tester reliability (ICC from 0.70 to 0.88) were high as was comparison to the automated method (ICC=0.90). These findings indicate that visual onset detection was highly reproducible between testing sessions, independent investigators and comparable to an automated method. These methods may be used reliably to determine the onset of MG muscle activity during a stretch-shorten-cycle muscle action.

Abstract: This study assessed the agreement between K vert calculated from 4 different methods of estimating vertical displacement of the center of mass (COM) during single-leg hopping. Healthy participants (N = 38) completed a 10-s single-leg hopping effort on a force plate, with 3D motion of the lower limb, pelvis, and trunk captured. Derived variables were calculated for a total of 753 hop cycles using 4 methods, including: double integration of the vertical ground reaction force, law of falling bodies, a marker cluster on the sacrum, and a segmental analysis method. Bland-Altman plots demonstrated that K vert calculated using segmental analysis and double integration methods have a relatively small bias (0.93 kN⋅m –1 ) and 95% limits of agreement (–1.89 to 3.75 kN⋅m –1 ). In contrast, a greater bias was revealed between sacral marker cluster and segmental analysis (–2.32 kN⋅m –1 ), sacral marker cluster and double integration (–3.25 kN⋅m –1 ), and the law of falling bodies compared with all methods (17.26–20.52 kN⋅m –1 ). These findings suggest the segmental analysis and double integration methods can be used interchangeably for the calculation of K vert during single-leg hopping. The authors propose the segmental analysis method to be considered the gold standard for the calculation of K vert during single-leg, on-the-spot hopping.

Abstract: The distal calcaneal wedge of the Kager's fat pad (KFP) has the mechanical role of lubricating the region between the Achilles tendon and calcaneus during ankle movements. The purpose of this study was to determine the reliability of real-time ultrasound (RTUS) in visualizing the motion of the KFP during walking in adults. Recordings obtained using RTUS (13-MHz linear array transducer, IOE 323, MyLab 70, Esoate, Genoa, Italy) of the Achilles enthesis region (N = 52) of 47 participants (ranging from 21-79 years in age) while walking on a motorised treadmill at their preferred speed were analysed by three blinded assessors. Motion of the KFP was rated on a 4-point Likert scale (normal to absent). There was good agreement (κ [95% confidence interval] = 0.646 [0.643-0.649]) among the three examiners, with very good agreement (0.823 [0.818-0.828]) when classifying the motion as normal. There was a poor correlation between the motion of the calcaneal wedge and participants' age (0.23-0.32). RTUS provides an adjunct to routine clinical examination to determine if there is normal motion of the calcaneal wedge during walking. This may be of benefit in patients with posterior heel pain for whom abnormal KFP motion is implicated.

Abstract: Adaptations in lower limb movement patterns were examined when performance was maintained during a fatiguing repetitive loading task. Forty recreationally active male and female participants performed single-leg hopping to volitional exhaustion at 2.2Hz to a submaximal height. Spatio-temporal characteristics, mechanical characteristics and variability of the knee-ankle and hip-knee joint couplings were determined at 20% increments during the duration of the hopping task. Variability of the knee-ankle and hip-knee couplings in the flexion/extension axis significantly increased during the loading and propulsion phases during the hopping task (p 0.05), however foot contact time increased progressively during this task (p<0.05) and maximum hop height significantly decreased after the task (p<0.05). The observed increase in variability between adjoining lower limb segments demonstrated the ability of the neuromotor system to adapt and maintain performance even with the onset of fatigue. This finding highlights that during the performance of a rapid and repetitive loading activity, performance can be preserved when there is variability in the neuromotor system.

Abstract: Women with pregnancy-related pelvic girdle pain (PPGP) report diminished ability to perform physical activities and experience higher rates of mood disorders, such as anxiety and depression, than pregnant women without PPGP. Despite these physical and psychological impacts, little is known about the lived experiences of PPGP amongst Australian women and the ways in which they cope. Situated within biographical disruption and social support theories, this study sought to gain a conceptual understanding of the experience and impact of PPGP on daily life, and how women cope with this condition during pregnancy. A qualitative research design, situated within a phenomenological framework, using in idual, semi-structured interviews consisting of open-ended questions was used with a flexible and responsive approach. Purposive s ling of pregnant women attending a single hospital included 20 participants between 14 and 38 weeks gestation, classified with PPGP as per recommended guidelines, with a mean (SD) age of 31.37 (4.16) years. Thematic analysis was performed where interview data was transcribed, coded, grouped into meaningful categories and then constructed into broad themes. Three themes were identified: 1. a transformed biography 2. coping strategies and 3. what women want. The pain experienced created a dramatic change in women’s lives, making the pregnancy difficult to endure. Women utilised social support, such as family, to help them cope with pain, and a self-care approach to maintain a positive mindset and reduce stress. Although a few women received support from healthcare professionals, many reported a lack information on PPGP and limited societal recognition of the condition. Women wanted early education, personalised information and prompt referral to help them cope with PPGP. Findings from this study highlighted the complexity of living with PPGP as women attempted to deal with the unexpected impact on daily life by seeking support from partners and families, while also struggling with societal expectations. Although women with PPGP used a number of coping strategies, they sought greater support from healthcare professionals to effectively manage PPGP. These findings have important implications for the provision of health care to women living with PPGP. Australian New Zealand Clinical Trials Registry: ACTRN12618001423202 .

Abstract: This study described changes in leg muscle activation characteristics during exhaustive single-leg hopping. Twenty-seven healthy men performed trials (132 hops/min) to exhaustion, without a target height, to a target height with visual feedback and target height with tactile feedback. Mean muscle activation litude of the medial gastrocnemius (MG) decreased during the anticipatory period while duration of MG activity was maintained when hopping to a target height and contrasted the changes during hopping without a target height. Changes to MG activity were specific to whether the hopping height had been maintained or not. Changes during the anticipatory period of MG activity, indicative of adaptation in descending motor pathways, implicate utility of a motor learning strategy to allow completion of an exhaustive task.

Abstract: Hand therapists often work in roles which require an advanced level of experience as Advanced Scope Practitioners (ASP). However, it is not known whether clinical decisions are similar between hand therapists and surgeons when managing simple hand fractures. To determine the level of agreement between (i) a hand therapist and five hand surgeons and (ii) three hand therapists, for the management of adults with closed metacarpal fracture(s). A prospective, blinded, crossover inter-rater reliability study. Patient volunteers with closed metacarpal fracture(s) were assessed independently in the first study (n = 90) by a hand therapist and one of five hand surgeons and in the second study (n = 57) by three hand therapists in a randomised order, with each practitioner recording whether the patient participant should be managed conservatively, trialled with conservative or offered surgical treatment. The level of agreement between the hand therapist and hand surgeons was calculated using Cohen's kappa coefficient and between the three hand therapists by calculating Fleiss' Kappa. The observed agreement was also calculated as the proportion of cases for which the assessors had agreement for management. There was good agreement between the hand therapist and surgeons (k = 0.68 95% CI: 0.537-0.831) and amongst the three hand therapists (k = 0.663 95% CI: 0.554-0.773) in determining the management of adults with closed metacarpal fracture(s). Hand therapists and surgeons make similar management decision for patients with metacarpal fractures supporting the role of hand therapists as ASP.

Abstract: This study aimed to determine whether real-time augmented feedback influenced performance of single-leg hopping to volitional exhaustion. Twenty-seven healthy, male participants performed single-leg hopping (2.2 Hz) with (visual and tactile feedback for a target hop height) or without feedback on a force plate. Repeated measures ANOVA were used to determine differences in vertical stiffness (k), duration of flight (tf) and loading (tl) and vertical height displacement during flight (zf) and loading (zl). A Friedman 2-way ANOVA was performed to compare the percentage of trials between conditions that were maintained at 2.2 Hz ± 5%. Correlations were performed to determine if the effects were similar when providing tactile or visual feedback synchronously with the audible cue. Augmented feedback resulted in maintenance of the tf, zf and zl between the start and end of the trials compared to hopping with no feedback (p 70% of total hops at 2.2 ± 5% Hz and this was significantly lower (p=0.01) with tactile (13/27) and visual (15/27) feedback. There was a strong correlation between tactile and visual feedback for duration of hopping cycle (Spearman's r=0.74, p ≤ 0.01). Feedback was detrimental to being able to maintain hopping cadence in some participants while other participants were able to achieve the cadence and target hop height. This indicates variability in the ability to use real-time augmented feedback effectively.

Abstract: Resilience refers to an in idual’s ability to maintain effective functioning, by resisting, withstanding or recovering from stressors or adversity, including pain associated with physical injury (J Clin Psychol Med Settings 28:518–28, 2021). The aim of this scoping review is to determine the role of resilience in the experience of movement-evoked pain (MEP) and return to functional activity following a musculoskeletal injury. This review conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews and the scoping review protocol of the Joanna Briggs Institute (JBI). Five databases and one grey literature database were searched using predetermined key words and index terms to capture published and unpublished records on the topic. Two authors independently screened the title and abstract of each record, with the full-text of eligible records being reviewed. Papers were eligible for inclusion if they examined the population, concept and context of interest, were written in English and the full text was available. Data were extracted from each eligible record to guide discussion of the available literature on this topic. Of 4771 records, 2695 articles underwent screening based on their title and abstract. After title and abstract screening 132 articles were eligible for full text review, with 24 articles included in the final analysis. This review identified that psychological resilience has primarily been investigated in the context of a range of age-related pathologies. The choice of functional and movement-evoked pain assessments in the included studies were often guided by the pathology of interest, with some being general or injury specific. This scoping review identified inconsistent conclusions regarding the role of resilience in the experience of MEP and the ability to return to function for older adults with a musculoskeletal injury. This scoping review highlights the need for longitudinal research to be conducted that allows a broader age range, including younger adults, to determine if multidimensional resilience may promote recovery form musculoskeletal injury.
