The rotator cuff is a collection of four muscles that help stabilize the shoulder. Other functions of this muscle group include arm abduction, external rotation, and internal rotation. The four muscles involved are the supraspinatus, infraspinatus, teres minor, and subscapularis. All have points of origin on the scapula and insert into the humerus (upper arm bone).
Kinesiotaping of the rotator cuff muscles aims to help support and provide additional stability to the four named muscles, allowing the body to perform more efficiently in daily activities or in an athletic environment. It can also aid in the healing process of sprains, strains, or minor tears that do not require surgery.
