The shoulder is one of the most mobile joints in the body, but its mobility comes with a trade-off—stability. The rotator cuff, a group of four muscles and tendons, plays a crucial role in maintaining both the mobility and stability of the shoulder joint. Here’s a quick look at what the rotator cuff is and
Symptoms of shoulder instability typically include a sensation of the shoulder slipping out of place or feeling loose, recurrent shoulder dislocations or subluxations, and chronic shoulder pain. Individuals may also experience weakness in the shoulder, a limited range of motion, and a feeling of apprehension or fear that the shoulder will dislocate during certain movements.
Shoulder instability is a condition characterized by excessive movement or looseness of the shoulder joint. It can lead to pain, weakness, and a feeling that the shoulder is going to “pop out” or dislocate. While it can occur due to trauma or dislocation, some individuals may experience chronic shoulder instability as a result of ligament
In order to perform normal, pain-free shoulder motion, it is necessary that there is adequate strength around the joint. While this sounds simple, normal shoulder motion depends on what are called “force couples” – opposing forces that act simultaneously on the shoulder during motion to provide stability. If these force couples are disrupted, abnormal motion
The Glenohumeral Joint The shoulder joint is primarily composed of the glenoid fossa of the scapula and the humerus and is medically referred to as the glenohumeral joint. This joint is the most mobile joint in the human body as it has considerable range of motion in multiple planes of movement. With this increased mobility
