Background of study: Shoulder problems are common complaint of the musculoskeletal system. Of all the shoulder problems shoulder impingement syndrome is one of the common. Significant advances in the area of anatomy and biomechanics of human shoulder has led to the identification of different types of impingement. Primary impingement is due to compression of the rotator cuff tendons between the humeral head and the overlying anterior third of acromion, coracoacromial ligament, coracoids or acromioclavicular joint. Impingement can also be secondary to underlying instability of glenohumeral joint. Attenuation of static and dynamic stabilizers of the glenohumeral joint, due to the excessive order during throwing or overhead activities can lead to anterior instability of the glenohumeral joint. Due to increased humeral head translation, the biceps tendon and rotator cuff can become impinged secondary to the ensuing instability. One more type of impingement in overhead athletes is termed as internal impingement and is due to repetitive impingement of undersurface of rotator cuff.
