Rotator cuff tears are the partial or full rupture of one or more of the rotator cuff tendons. The rotator cuff muscles include: the supraspinatus, infrapsinatus, teres minor, and subscapularis. Tears are often the result of trauma/fall, or impingement (see shoulder impingement) due to poor postural habits. Individuals with rotator cuff tears may experience pain when lying on the affected arm or performing overhead or behind the back activities. Physiotherapy is effective by addressing poor scapular stability/control, strengthening the rotator cuff muscles, stretching tight structures and correcting posture.
