The goal of this clinical trial is to learn whether a Nintendo Switch-based exergame physical activity program can help children and adolescents with congenital heart disease increase their physical activity. It will also learn about the safety, acceptability, and feasibility of this program. The study will include children and adolescents aged 8 to 18 years who have congenital heart disease, have received surgical or interventional treatment, and are clinically stable.
The main questions it aims to answer are:
Does the exergame-based program increase the amount of time participants spend in moderate-to-vigorous physical activity each day? Is the exergame-based program safe, acceptable, and feasible for children and adolescents with congenital heart disease?
All participants will receive the same exergame-based physical activity program. Researchers will use different baseline observation periods to help understand whether changes in physical activity happen after the program starts.
Participants will:
Wear an activity monitor to measure daily physical activity. Complete a baseline observation period lasting 7, 14, or 21 days. Take part in a 12-week Nintendo Switch-based exergame physical activity program with guidance, goal setting, self-monitoring, feedback, and caregiver support.
Complete a 2-week observation period after the program to see whether physical activity changes are maintained.
Complete study assessments at screening, the end of baseline, week 4, week 8, week 12, and the end of the observation period.
Researchers will also collect information on step counts, energy expenditure, self-reported physical activity, exercise capacity, quality of life, adherence, acceptability, and adverse events.
