Rotator cuff up recovery time and allowing the person to better perform optimally. A study conducted by Jin-Young Park investigated the benefits of using capsular release to help relieve the stiffness of the shoulders that usually come whenever there is an injury in the rotator cuff. Some of the subjects had diabetes mellitus, which can also cause shoulder stiffness, impeding external rotation of the shoulders. Of the 49 subjects recruited for this trial, 21 went through only manipulation to relieve stiffness, while the other 28 underwent a capsular release surgery along with the manipulation to treat shoulder stiffness. Although, overall, no improvement
Rotator cuff arm, moving it outward and away from the trunk, the rotator cuff compresses the glenohumeral joint, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. The anterior and posterior directions of the glenoid fossa are more susceptible to shear force perturbations as the glenoid fossa is not as deep relative to the superior and inferior directions. The rotator cuff's contributions to concavity compression and
