Effects of a 12 week community-based high-level mobility programme on sustained participation in physical activity by adolescents with cerebral palsy: a single subject research design study.

Health professionals' promotion of sustained participation in physical activity needs to consider individual preferences for frequency, diversity and duration.Supporting and measuring involvement in physical activity should be prioritised as a key outcome of an intervention.Physical activity interventions should be followed up for longer than six months to determine sustained changes in participation outcomesMeasuring physical capacity and performance gains alone is insufficient to determine sustained, meaningful participation.
