Progressive resistance training in young people with Prader-Willi syndrome: protocol for a randomised trial (PRESTO)

INTRODUCTION

Preliminary evidence suggests that progressive resistance training may be beneficial for people with Prader-Willi Syndrome (PWS), a rare genetic condition that results in muscle weakness and low muscle tone.To establish whether community-based progressive resistance training is effective in improving the muscle strength of people with PWS; to determine cost-effectiveness; and, to complete a process evaluation assessing intervention fidelity, exploring mechanisms of impact, understanding participant experiences and identifying contextual factors affecting implementation.

METHODS AND ANALYSIS

A multisite, randomised controlled trial will be completed. Sixty participants with PWS will be randomised to receive either progressive resistance training (experimental) or non-progressive exercise (placebo control). Participants will be aged 13 to 60 years, be able to follow simple instructions in English and have no contraindications to performing progressive resistance training. The experimental group will complete progressive resistance training two times weekly for 24 weeks supervised by an exercise professional at a community gym. The control group will receive all aspects of the intervention except progressive overload. Outcomes will be assessed at week 25 (primary endpoint) and week 52 by a blinded assessor. The primary outcome is muscle strength assessed using one repetition maximum for upper limb and lower limb. Secondary outcomes are muscle mass, functional strength, physical activity, community participation, health-related quality of life and behaviour. Health economic analysis will evaluate cost-effectiveness. Process evaluation will assess safety and intervention fidelity, investigate mechanism of impact, explore participant experiences and identify contextual factors affecting implementation. Data collection commenced in February 2020 and will conclude in September 2023.

ETHICS AND DISSEMINATION

Ethical approval was obtained from The Royal Children's Hospital Human Research Ethics Committee (HREC/50874/RCHM-2019) under the National Mutual Acceptance initiative. Research governance approvals were obtained from five clinical sites. Results will be disseminated through published manuscripts, conference presentations, public seminars and practical resources for stakeholder groups.

Feasibility of scaling-up a community-based exercise program for young people with disability

PURPOSE

To evaluate feasibility of scaling up a 12-week community-based exercise program (FitSkills) in which young people with disability exercise with a student mentor.

METHOD

Within a stepped wedge cluster randomised trial, seven domains of feasibility were assessed: demand, implementation, acceptability, practicality, adaptation, integration, and expansion.

RESULTS

Of the 163 participants with disability (61 females; 20.8 ± 5 y) and 226 mentors who enrolled, 123 participants and mentors completed FitSkills. Population demand was estimated at 9% of members of participating organisations. Most participants (76%) completed the twice-weekly program within 12 weeks, attending 79% of sessions (mean 18.9 ± 4.7). Key program elements valued by participants were the mentor, tailored exercise, and regular program schedule. Majority (87%) of mentors were recruited from physiotherapy, occupational therapy, and exercise science courses. Positives for participants were perceived benefits and organisational support, and for mentors, understanding disability. Communication and scheduling were burdens. Three serious and 28 non-serious adverse events occurred. Adaptations (additional screening, risk analysis, extra mentor support, or in-person consultation) enabled 29 young people with complexity to participate. The number of trial sites was expanded to 11 to accommodate participants.

CONCLUSIONS

Scaling-up FitSkills is feasible, but with caveats related to communication, scheduling, and efficiency of recruitment.IMPLICATIONS FOR REHABILITATIONKey elements valued by participants as part of the successful scale-up of a community-based exercise program (FitSkills) across a large metropolitan city included a peer-mentor, tailored exercise, and organisational support structure.FitSkills can be adapted to include young people with complex disability with additional supports including screening, risk analysis, and professional support for the peer-mentor.The benefits of FitSkills, including social connectedness for young people with a disability and normalisation of disability for mentors, outweigh the burdens of participation.Communication with program organisers and scheduling logistics between the young person, their family/carers and peer mentors are important factors to manage for the successful implementation of FitSkills.

Physiotherapy departments in Australian tertiary hospitals regularly participate in and disseminate research results despite a lack of allocated staff: a prospective cross-sectional survey

OBJECTIVES

To establish the level of research activity in physiotherapy departments of Australian tertiary hospitals.

DESIGN

Prospective cross-sectional survey.

PARTICIPANTS

Physiotherapy managers from 37 principal referral hospitals and specialist women's and children's hospitals as identified from the Australian Institute of Health and Welfare (2011).

MAIN OUTCOME MEASURES

A purpose-designed predominantly open-response questionnaire investigating site demographics, research activity and research support was developed, piloted and administered.

RESULTS

Thirty-seven surveys were completed (54% response rate). Median [IQR] respondent equivalent full-time staffing was 23.8 (19-39). Respondents represented a median [IQR] 6.5 (3-20) publication output in the past 2 years. Twelve respondents (32%) reported that staff had completed a doctorate in the past 5 years and 49% of respondents reported no staff had completed higher degrees. A total of 71 grants had been received and 73% of respondents indicated they had no allocated staffing for research activity. The most common indicators of research culture were organization-led research dissemination events and research training (i.e. manager attending research events and celebrating research achievements).

CONCLUSIONS

This is the first study to report on research activity in hospital-based Australian physiotherapy departments. Few sites allocate staff to conduct or support research. Despite this, physiotherapy departments regularly publish and present research results. Future studies could investigate how hospital-based physiotherapy departments can optimize research culture and output.
