The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping inferiorly. [5] The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position. [5]
Active exercises include the Pendulum exercise, which is used to strengthen the Supraspinatus, Infraspinatus, and Subscapularis. [9] External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles.
The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9] These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral joint, along with humeral abduction.
The empty can and full can exercises are amongst the most effective at isolating and strengthening the supraspinatus. [87] Following arthroscopic rotator-cuff repair surgery, individuals need rehabilitation and physical therapy. [88] Exercise decreases shoulder pain, strengthens the joint, and improves range of motion.
The abovementioned human rotator cuff study correlates pennation angle with tear length in the supraspinatus muscle. Therefore, a patch graft may not resolve the length change necessary to restore pennation angle; retraction of the torn tendon may lessen the post-tear pennation angle and restore muscle strength to a greater extent.

The muscles of the rotator cuff are supraspinatus, subscapularis, infraspinatus, and teres minor. The cuff adheres to the glenohumeral capsule and attaches to the humeral head . The shoulder must be mobile enough for the wide range actions of the arms and hands, but stable enough to allow for actions such as lifting, pushing, and pulling.
Supraspinatus muscle helps in 0°-15° arm abduction. And Infraspinatus helps in lateral rotation (external rotation) of humerus. Suprascapular nerve entrapment syndrome , causing shoulder pain and localized muscular atrophy of the supraspinatus and infraspinatus muscles.
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.
