The rotator cuff is the attachment of the supraspinatus, infraspinatus, subscapularis, and teres minor. It serves an important role in slowing down the accelerating arm in an overhead movements (i.e. swimming, throwing, other related sporting activities) by keeping the humeral head in the glenoid fossa. These repetitive overhead movements may cause small microscopic tears in the rotator cuff, making it painful to perform overhead activities.
The training program for a client with a rotator cuff injury will focus on strengthening the muscles that stabilize the humeral head during overhead activities.
