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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Other: RaceRunning|RaceRunning (www.racerunning.org) is a growing disability sport that provides an opportunity for people with moderate-to-severe CP to participate in exercise in the community. It allows those who are unable to walk independently, to propel themselves using a RaceRunning bike, which has a breastplate for support but no pedals. Participants sit on the saddle and use their legs to propel themselves forward.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| maximum aerobic capacity (VO2max) | an incremental test protocol will be used to measure the maximum oxygen uptake (ml/ min kg) an incremental test protocol will be used to measure maximum oxygen uptake (ml/min kg) | Baseline, 12 weeks and 24 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physical activity | The number of steps over five 24 hour periods will be recorded using an activity monitor. | Baseline, 12 weeks and 24 weeks | 
| sedentary behaviour | The time (in minutes) spent in an lying or sitting over five 24 hour periods will recorded using an activity monitor. | Baseline, 12 weeks and 24 weeks | 
| Resting heart rate (beats per min) | The average heart rate during 2 minutes of quiet sitting | Baseline, 12 weeks and 24 weeks | 
| Resting heart rate blood pressure (mmHg) | The average blood pressure during 2 minutes of quiet sitting | Baseline, 12 weeks and 24 weeks | 
| Functional mobility Scale | The Functional Mobility Scale (FMS) will be used to describe the level of a child's mobility in everyday life over 5m, 50m, and 500m and representing the home, school and community settings respectively. | Baseline, 12 weeks and 24 weeks | 
| Muscle strength | Knee extensor strength (N) will be assessed with a hand-held dynamometry | Baseline, 12 weeks and 24 weeks | 
| calf and waist circumference (mm) | The circumference of the calf and waist will be measured using a tape measure | Baseline, 12 weeks and 24 weeks | 
| Quality of Life (EQ-5D) | The EQ-5D-Y/EQ-5D-5L will be used to describe and value the health in terms of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. | Baseline, 12 weeks and 24 weeks | 
| The Canadian Occupational Performance Measure | The Canadian Occupational Performance Measure will be used to identify important activities for each participant and to record the change in participants' perceived performance rating of this activity and the satisfaction of this performance over time. psychosocial outcomes such as happiness, self-esteem, independence and quality of life. | Baseline, 12 weeks and 24 weeks | 
| Psychosocial Impact of Assistive Devices Scale (PIADS) | The PIADS will be used to record the change in psychosocial outcomes such as happiness, self-esteem, independence and quality of life as a result of using a specific assistive device (RaceRunner). | Baseline, 12 weeks and 24 weeks |
