Summary

This study tests two approaches to help people with knee osteoarthritis stay active after physical therapy: a game-like reward system with social support, and health coaching. About 254 veterans will use a Fitbit and smartphone app to track their progress. The goal is to see if these methods improve long-term pain, function, and exercise habits.
