Iontophoresis Protocol: Rotator Cuff Syndrome
The rotator cuff is composed of the supraspinatus. infraspinatus, teres minor and subscapularis muscles. These four muscles form the musculotendinous cuff that provides stability to the glenohumeral joint. Through the action of one or all four, a rotary force causes rotation of the humerus and compression of the humeral head into the glenoid fossa.
Degeneration and subsequent tearing of the rotator cuff at its tendon of insertion is common and results in restriction of shoulder movement, especially abduction. The supraspinatus is most commonly ruptured at its insertion. Additionally, the anterior part of the infraspinatus tendon, the long head of the biceps, the anterior one third of the acromion, coraco-acromial ligament and the acromioclavicular joint structures are involved.
Rotator cuff syndrome is a common overuse injury usually caused by repetitive overhead activities (swimming, pitching. tennis) or through direct trauma. Repeated microtrauma starts a painful cycle of inflammation-edema-increased tendon volume and decreased suprahumeral space.
