Physical and occupational therapy aims to reduce pain and improve joint function through a multimodal program. The program includes joint conservation, energy conservation, splinting, range of motion exercises, and the application of heat and cold. Exercises are tailored to each patient's condition and may include aerobic conditioning to build endurance when symptoms permit. Therapists also provide education on properly modifying activities, maintaining a healthy weight, using assistive devices, and adapting the home environment to reduce stress on joints.
