Reliability of lower limb strength assessment in female team sport athletes.

BACKGROUND: Lower limb injury rates have increased dramatically in line with increased female sport participation levels. Muscle strength is a modifiable lower limb injury risk factor, guiding performance monitoring and rehabilitation. OBJECTIVES: The aim of this study was to investigate the test-retest reliability of isokinetic and isometric lower limb peak torque to body mass of muscles acting on the hip, knee, and ankle in female team sport athletes. It was hypothesised the test-retest reliability would be good (intraclass correlation coefficients (ICC) ≥ 0.75). METHODS: Thirty-eight female athletes (Australian Rules Football = 18, netball = 12, soccer = 8) aged 16-35 years participated in this study. Participants performed isokinetic (60°/s and 120°/s) and isometric testing on a Biodex Isokinetic Dynamometer on three separate days. RESULTS: Poor to good reliability was demonstrated for all joint movements (ICC = 0.38-0.88) with small to moderate effect sizes (0.00-0.43) and typical errors (5.65-24.49). CONCLUSION: Differences in peak torque to body mass were observed between sessions one and two and/or one and three, demonstrating a learning effect. Therefore, three testing sessions, and/or the inclusion of a familiarisation session, is recommended for future assessments in populations unfamiliar with dynamometry.

Developing and Planning a Protocol for Implementing Health Promoting Animal Assisted Interventions (AAI) in a Tertiary Health Setting.

The Ottawa Charter identifies that multiple levels of government, non-government, community, and other organizations should work together to facilitate health promotion, including in acute settings such as hospitals. We outline a method and protocol to achieve this, namely an Action Research (AR) framework for an Animal Assisted Intervention (AAI) in a tertiary health setting. Dogs Offering Support after Stroke (DOgSS) is an AR study at a major tertiary referral hospital. AAI has been reported to improve mood and quality of life for patients in hospitals. Our project objectives included applying for funding, developing a hospital dog visiting Action Research project, and, subsequent to ethics and governance approvals and finance, undertaking and reporting on the Action Research findings. The Action Research project aimed to investigate whether AAI (dog-visiting) makes a difference to the expressed mood of stroke patients and their informal supports (visiting carers/family/friends), and also the impact these visits have on hospital staff and volunteers, as well as the dog handler and dog involved. We provide our protocol for project management and operations, setting out how the project is conducted from conception to assess human and animal wellbeing and assist subsequent decision-making about introducing dog-visiting to the Stroke Unit. The protocol can be used or adapted by other organizations to try to avoid pitfalls and support health promotion in one of the five important action areas of the Ottawa Charter, namely that of reorienting health services.

Reliability of the running vertical jump test in female team sport athletes.

Injury rates to the lower limb have increased over the past 40 years, coinciding with increases in female sport participation rates. Sport specific tests such as the running vertical jump (RVJ) are utilised for injury risk profiling, however the test-retest reliability is unknown. OBJECTIVES: The aim of this study was to investigate the test-retest reliability of the thorax, pelvis and lower limb joint angular kinematics and kinetics for the RVJ test in female team sport athletes. DESIGN: Three-dimensional motion capture with force plate integration was utilised as participants performed five trials on each limb on three separate days. SETTING: Testing occurred in a biomechanics laboratory. PARTICIPANTS: Thirty-four females (Australian Rules Football = 15, Netball = 12, Soccer = 7) participated in this study. MAIN OUTCOME MEASURES: Intraclass correlation coefficients (ICC), effect sizes and typical errors (TE) of segment and joint angular kinematics and kinetics were calculated. RESULTS: Poor to excellent reliability (ICC = -0.12 - 0.92), small to large effect sizes (0.00-0.90) and TE (0.02-289.24) were observed across segment and joint angular kinematics and kinetics. CONCLUSIONS: The RVJ test is recommended when analysing ground reaction forces and joint angular kinematics in female team sport athletes.

Assistance dogs in occupational therapy practice: A survey of Australian occupational therapists' experiences and recommendations.

INTRODUCTION: Assistance dogs perform multiple tasks to support people with disabilities and bring various benefits. Occupational therapists play a key role in assessing or referring clients for assistive technology, which includes assistance dogs. However, little is known about Australian occupational therapists' experiences with assistance dogs and how they perceive their roles in this area of practice. METHODS: A cross-sectional online survey was developed and distributed nationally to Australian occupational therapists to glean their experiences and perceptions of assistance dogs and their recommendations to support future practice. RESULTS: A total of 220 completed surveys were received with all perceiving assistance dogs as beneficial for clients with disabilities. Over 60% agreed it was within their scope to assess or refer clients for assistance dogs, but more than two thirds had not had the occasion to do so and/or lacked relevant education and training. Common difficulties experienced in the referral or assessment process include challenges with accessing and navigating funding, lack of resources and/or assistance dogs, and perceived insufficient evidence to support the use of assistance dogs. CONCLUSION: Findings indicate that occupational therapists' lack experience and knowledge of assistance dogs although they perceive assistance dogs as within the scope of occupational therapy practice. This study highlights a need for increasing professional development opportunities for occupational therapists regarding assistance dogs, including assessment and referral processes. This will be steadily more important given the increasing profile and expanding application of assistance dogs, and funding organisation requests for occupational therapists in assessing clients for assistance dogs.

Changes in power assessed by the Wingate Anaerobic Test following downhill running.

Few studies have examined the effects of eccentric exercise-induced muscle damage on power despite power being a key performance variable in a number of sporting events. The aim of this study was to examine changes in anaerobic power (30-second Wingate Test), isometric strength of the knee extensors and flexors, muscle soreness, and plasma creatine kinase (CK) activity following downhill running. Eight men performed a 40-minute downhill (-7%) run on a treadmill, and measurements were taken on 6 occasions (2 baseline and 0.5, 24, 72, and 120 hours postrun). A second group of men (n = 5) had the measurements taken on 6 occasions without downhill running and served as a control group. A repeated measures analysis of variance revealed no significant changes in any measures across time for the control group. Following downhill running, significant (p < 0.05) decreases in strength (0.5-24 hours), and significant increases in muscle soreness (0.5-72 hours) and plasma CK activity (0.5-120 hours) were observed. A significant decrease in peak and average power (approximately 5%) was evident only 0.5 hours postrun, and the decrease was smaller in magnitude than that of strength (approximately 15%). These results suggest that power is less affected than strength after eccentric exercise, and the effect of reduced power on sport performance seems negligible.
