Precision-based Teleexercise Trial to Increase Adherence in People With Disabilities

What this Trial Is About

Researchers are studying how to best increase physical activity in people with mobility impairments through a 32-week program using a design called SMART (Sequential Multiple Assignment Randomized Trial). This approach tests the best way to combine teleexercise with predictive analytics to adapt the support participants receive based on their exercise adherence. The study aims to find effective strategies for improving activity levels while exploring factors that influence outcomes and testing the accuracy of prediction methods. Participants first complete a run-in period including consent, surveys, and setup of an exercise tracker and band. They are then randomly assigned to either an Asynchronous Exercise Program (AEP) or AEP plus Smart Health Coaching (SHC). All receive access to an online platform with exercise videos and wellness articles. After 4 weeks, participants are assessed for response; those not responding are re-randomized to receive live one-on-one or group exercise sessions via Zoom for the next 4 weeks. Following this, all participants enter a 24-week maintenance phase with access to prerecorded content only. Throughout the study, participants wear a tracker to monitor steps and activity, complete surveys at baseline, week 8, week 16, and week 32, and may have reminder calls to encourage survey completion. Data collected includes physical activity, health literacy, secondary health conditions, and activity limitations. Interviews are conducted after the adoption phases to gather further insights. The total participation lasts 32 weeks, with ongoing collection of exercise and website usage data to evaluate the adaptive interventions.
