Shoulder rehabilitation for the arthritic glenohumeral joint: preoperative and postoperative considerations.

Arthritis of the glenohumeral joint can cause pain, weakness, and limit motion. Preoperative treatment consists of physical therapy to manage pain, increase shoulder motion, and increase rotator cuff and scapulothoracic muscle strength. The postoperative three-phase rehabilitation program described is structured, supervised, and involves the cooperation of the patient, surgeon, and physical therapist. Rate of progression and ultimate outcome is based on underlying pathology, surgical technique, and patient tolerance to exercise. Patients with an intact rotator cuff should be expected to tolerate a more aggressive rehabilitation program and expect a higher functional outcome. Those with a deficient cuff mechanism can expect more modest gains oriented toward restoring pain-free functional activity.
