Vascular changes in the rotator cuff tendons are considered intrinsic factors because they originate within the structure of the rotator cuff itself. Hypertrophic degenerative changes of the acromioclavicular joint and the shape of the acromion are extrinsic factors that affect the suprahumeral space. Increased thoracic extension can also be considered an extrinsic factor because it affects the position and movement of the shoulder joint, rather than originating within the rotator cuff itself.
