sculderfunksjon

sculderfunksjon refers to the functional capacity of the shoulder complex, including the joints, muscles, and soft tissues that enable movement and stability of the upper limb.

The shoulder framework comprises the glenohumeral joint, the acromioclavicular and sternoclavicular joints, and the scapulothoracic articulation. The rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis), the deltoid, and the periscapular muscles provide strength, while ligaments and the joint capsule offer passive stability.

Scapulohumeral rhythm coordinates shoulder girdle motion with humeral movement to achieve full elevation. The joint allows a wide range of motion, including flexion, extension, abduction, adduction, rotation, and circumduction, while distributing loads across the arm to protect the humeral head.

Impairments in sculderfunksjon can arise from injury or disease, such as rotator cuff tears, shoulder impingement, dislocations, adhesive capsulitis, or nerve injuries (e.g., axillary or suprascapular nerves). Evaluation includes range of motion, strength testing, functional assessment, and imaging as needed.

Management focuses on restoring mobility, strengthening the rotator cuff and periscapular muscles, and retraining neuromuscular control and proprioception, often through physical therapy, activity modification, and progressive loading. Maintaining good posture and conditioning supports long-term shoulder function.
