which muscles are part of the rotator cuff
Rotator cuff In anatomy, the rotator cuff [1]) is a group of muscles and their tendons that act to stabilize the shoulder. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle.
Dead arm syndrome The shoulder is unstable and dislocation may come next. Dead arm syndrome will not go away on its own with restâ€”it must be treated. If there is a SLAP lesion, then surgery is needed to repair the problem. If the injury is caught before a SLAP tear, then physical therapy with stretching and exercise can restore it.
