What is the role of exercise in OA therapy?
A specific exercise program can play a significant role in improving the joint range of motion and function and in reducing pain. Several studies have shown that a supervised program of fitness walking results in the improvement of pain and joint function. Other studies have shown that exercise can improve psychological well-being.
The ideal exercise should be one that minimizes weight-bearing but enables joint range of motion, muscle strengthening, and aerobic fitness. It is important that the individual selects an exercise program that is enjoyable, easily done, and possible to accomplish. Therefore, swimming can be an excellent option. When done in a warm pool, the individual can move affected joints, strengthen periarticular muscles, and improve cardiovascular fitness, all without bearing weight on diseased joints. Other good options include bicycling, walking, elliptical training, and cross-country skiing.
