The shoulder is an intricate joint, capable of a wide range of movements for both daily activities and physical exercise. This intricate joint is susceptible to various injuries and conditions due to its design. Shoulder impingement syndrome (SIS), also clinically recognized as subacromial impingement syndrome (SAIS), is a prevalent source of shoulder discomfort, which is a spectrum of disorders such as rotator cuff tendinopathy, partial or complete tears, and inflammation of the subacromial bursa.
