1. Introduction The rotator cuff muscle group is composed of the subscapular, teres minor, supraspinatus, and infraspinatus muscles. Its tendon forms a sleeve-like structure at the anatomical neck of the humeral head. The most important function of the rotator cuff is to ensure the stability of the shoulder joint (1). The estimated prevalence of shoulder pain in the population is approximately 16%–34% (2, 3), and rotator cuff problems are one of the main causes of shoulder pain.
