Remote Group and Individual Coaching to Increase Daily Steps, Reduce Pain, and Support Weight Loss in Older Adults with Knee or Hip Osteoarthritis

What this Trial Is About

Researchers are studying chronic pain in older adults, focusing on those with knee or hip osteoarthritis. This trial evaluates a mobile, remotely delivered behavioral intervention aimed at increasing physical activity and improving diet to reduce pain and enhance quality of life. The goal is to see if this approach can increase daily steps, reduce pain interference, lower body weight, and improve physical function over 6 months, with a follow-up maintenance phase lasting 12 months. Participants will be randomly assigned to one of two groups. The intervention group will join weekly group sessions with peers and receive individual coaching calls to encourage moving often throughout the day and adopting healthier eating habits to lose weight. They will use an activity monitor and a mobile app for feedback and goal-setting. The comparison group will receive an activity monitor and a wireless weight scale but no behavioral intervention. After 6 months, all participants enter a 12-month no-contact period to maintain their progress independently. During the study, participants will be assessed on daily steps, pain interference, body weight, physical function tests like the 30-second chair stand and gait speed at baseline, 6 months, and 18 months. Researchers will monitor changes in these areas to measure the interventions effectiveness. Participants will attend virtual testing appointments and complete questionnaires, with the total study duration being 18 months including follow-up.
