What is the Rotator Cuff?

 The rotator cuff is comprised of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis. All of these muscles originate on the shoulder blade and insert somewhere on the humerus (upper arm bone).

Now, each one of these muscles has their own action, or job, that they perform. Whether the action is abduction of the arm, internal or external rotation, or inferior glide of the humerus, each is important for shoulder health. In addition to these actions, the muscles create stability within the glenohumeral (shoulder) joint. Without a healthy rotator cuff, the shoulder joint can begin to feel “sloppy” and unstable. 

Injury to these muscles typically occur in two ways. First, trauma, like falling on an outstretched arm, can cause a strain or tearing in the muscles. Secondly, a repetitive use injury, like repeatedly throwing a baseball, can cause a strain or tendonitis. The severity of the injury can span from a minor strain to a complete, or full thickness, tear. Diagnostic imaging, usually an MRI, confirms the severity of the injury following a examination.

Examination

At Elite Sport & Spine, the chiropractors will perform a thorough examination to determine the severity of the rotator cuff injury. The examination will also determine if imaging is necessary to evaluate for tearing in the muscles. The examination usually consists of orthopedic testing, range of motion, and muscle strength tests. Our chiropractors will also use palpation and functional movement screens to further assess the injury in more depth. 

Treatment

Once the severity of the injury has been determined, the chiropractor can begin the treatment and rehabilitation of the rotator cuff. Myofascial release, either done by hand or with an instrument, can help release adhesions and allow the muscles to perform their actions more effectively.

Furthermore, spinal and/or extremity manipulation can be performed to improve joint movement and function. In addition,  a major component of improving rotator cuff health is through specific rehabilitation exercises designed to improve the stability of the entire shoulder complex.
