Shoulder impingement syndrome (SIS) was found to account for 44% to 65% of overall shoulder pain (Windt et al., 1995). SIS may be defined as the mechanical compression of the rotator cuff tendons, biceps tendon and sub-acromial bursae beneath the coracoid-acromial arch (McClure et al.,2006). This review will discuss generalised impingement however it is important to note that research by Edelson and Teitz 2000 divided SIS into categories of Sub –acromial (external impingement occurs on bursal side), internal impingement anterior/posterior (gleno-humeral aspect) and coracoid impingement (compression via coracoid process). Jobe et al 2000 state that issues with posture and poor scapular kinematics are they most common causes of SIS by causing
