What Is The Function Of The Rotator Cuff?
There are four muscles that make up the rotator cuff. They are the supraspinatus, infraspinatus, teres minor, and subscapularis. The primary function of the rotator cuff is to hold the shoulder joint securely during overhead movement. If tendonitis or a tear of the rotator cuff is present, it will be difficult and painful to use your arm for even the simple tasks of daily life.
