RaceRunning for Young People With Moderate-to-severe Cerebral Palsy

Physical inactivity in people with cerebral palsy (CP) has been linked with increased risk of cardiometabolic disease. Exercise studies rarely include people with CP with severe walking impairments and assess the sustainability of the intervention. RaceRunning allows people severe walking impairments to independently propel themselves using a running bike, which has a breast plate for support but no pedals. This project will assess the feasibility of at trial into the effectiveness of RaceRunning to reduce cardiometabolic disease risk factors and improve functional mobility. Intervention: Weekly standardised RaceRunning sessions over 6 months led by an experienced coach. Participants Twenty-five young people with CP aged 5-21, GMFCS levels III-V. Feasibility outcomes: Acceptability of RaceRunning, adherence and fidelity of the intervention, recruitment and retention rates and adverse events. Outcome measures: Cardiometabolic disease risk factors (physical activity, sedentary time, resting heart rate and blood pressure and aerobic capacity) and functional mobility assessed at baseline, 3 and 6 months. Quality of life (EQ-5D-Y) and health service use will inform a future cost-effectiveness analysis. Aspects of feasibility and acceptability and the variability and patterns of the change in outcomes will be reported using descriptive statistics.

This is a multi-centre experimental study with a single intervention arm. Assessments will be conducted at baseline, 12 weeks and 24 weeks. The intervention will be delivered in Scotland and Gloucestershire. Participants will take part in one RaceRunning session each week for a period of 24 weeks. The content of the sessions will be standardised for all training groups and will consist of a warm-up, coordination (drills), sprint and endurance training, and cool-down. The training program will be adapted to the athlete's ability and fitness. The project objectives are to examine the feasibility of delivering and acceptability of participating in RaceRunning as a community-based intervention for young people with moderate-to-severe CP, including fidelity to and safety of the intervention. Secondly, to examine the feasibility of conducting a definitive study of RaceRunning including exploring recruitment and retention over 24 weeks, acceptability of data collection methods and rate of outcome measure completion, and acceptability and quantity of missing data relating to health economic data collection tools. Finally, to examine the variability and patterns of change in outcomes over 24 weeks in order to determine a primary outcome measure and calculate sample size for a future study.
