Effects of a Self-directed Web-Based Strengthening Exercise and Physical Activity Program Supported by Automated Text Messages for People With Knee Osteoarthritis: A Randomized Clinical Trial.
Exercise therapies are advocated in osteoarthritis (OA) clinical guidelines. However, challenges to accessing exercise may be limiting widespread uptake. ⋯ This randomized clinical trial found that a self-directed web-based strengthening exercise regimen and physical activity guidance supported by automated behavior-change text messages to encourage exercise adherence improved knee pain and function at 24 weeks. This unsupervised, free-to-access digital intervention is an effective option to improve patient access to recommended OA exercise and/or to support clinicians in providing exercise management for people with knee OA at scale across the population.
