Extra Corporeal Shock Wave Versus Phonophoresis in Sub Acromial Impingement Syndrome.

shoulder sub acromial impingement syndrome is an encroachment of subacrormial tissues, rotator cuff, subacrormial bursa, and the long head of the biceps tendon, as a result of narrowing of the subacrormial space. Activities requiring repetitive or sustained use of the arms over head often predispose the rotator cuff tendon to injury. Hence the objective of the study is to examine the influence of extra corporeal Shock wave versus phonophoresis on pain severity and functional disability in patients with sub acromial impingement syndrome.
