Full Definition
The rotator cuff (supraspinatus, infraspinatus, subscapularis, teres minor) provides dynamic stability to the glenohumeral joint. In golf, the trail shoulder is at greatest risk: the late-cocking phase of the backswing stresses the supraspinatus and infraspinatus, while the deceleration phase after impact stresses the subscapularis and teres minor. Risk factors: steep takeaway (creates impingement position at top), over-acceleration (rapid speed creates extreme deceleration forces), and poor posture (forward head/shoulders increases impingement zone). Prevention: rotator cuff strengthening (external rotation with resistance band) and mechanics correction to reduce steep downswing angles.
