skuldermekanik

Skuldermekanik is a term that describes the mechanical principles involved in the movement and function of the shoulder joint. The shoulder, or glenohumeral joint, is a ball-and-socket joint that allows for a wide range of motion, including abduction, adduction, flexion, extension, internal rotation, and external rotation. This extensive mobility is due to the shallow socket (glenoid fossa) which receives the humeral head.

The stability of the shoulder joint is primarily maintained by the rotator cuff muscles, a group of four muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) and their tendons. These muscles not only facilitate movement but also actively compress the humeral head into the glenoid fossa, providing dynamic stability. The joint capsule, a fibrous structure enclosing the joint, and ligaments also contribute to passive stability.

Understanding skuldermekanik is crucial in diagnosing and treating various shoulder conditions. Injuries such as rotator cuff tears, dislocations, and impingement syndrome often arise from dysfunctions in the coordinated mechanics of the shoulder. Rehabilitation programs for these conditions focus on restoring proper muscle activation, strength, and movement patterns to optimize the mechanical efficiency of the shoulder. Biomechanical analysis plays a significant role in assessing shoulder function and identifying underlying causes of pain or limited mobility.
