Technology Utilisation and Engagement in Physical Activity of Adolescents With Intellectual Disabilities: A Scoping Review.

This is a scoping review, not a test of whether technology improves physical activity. Most included studies were descriptive or cross-sectional, so they can show associations but not cause. Only three randomised trials were included, and the interventions often combined exercise, education, reminders, incentives, diet or parent support, making it hard to know what component mattered. Study quality was often low: 69% of included studies met three or fewer quality appraisal criteria. Many studies did not report the level of intellectual disability or support needs, and only 16% reported race, so the findings may not fit all adolescents with intellectual disabilities. No qualitative studies met inclusion criteria, so adolescents' own views of technology were rarely captured. Activity devices varied in model, wear location, wear time and analysis settings, making comparisons across studies difficult. Most research came from the United States, Spain and China, limiting cultural and service-system generalisability.

The authors report no conflicts of interest and nothing to report for funding or ethics declarations.

Do not conclude that exergaming or fitness trackers improve physical activity in adolescents with intellectual disabilities. The review found only a few small intervention studies, many of low quality, and programmes often combined technology with exercise, coaching, reminders, incentives, diet, or parent support, so the effect of the technology alone is unclear.
