The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.
A rotator cuff is comprised of four muscles (supraspinatus, infraspinatus, subscapularis, and teres minor) located in the shoulder area, which provide support to the shoulder joints. Any kind of rotator cuff injury, such as a subscapularis tear, can result in scapular pain.
