Scapula Dyskinesis

Abstract

Scapular dyskinesis is any alteration of its static position or kinematics during movements in the shoulder joint. The correct scapula orientation is associated with the tone of the muscles attached to it. The prevalence of scapular dyskinesis is high among patients with subacromial impingement syndrome, partial rotator cuff tears, shoulder joint instability and SLAP injuries. Scapular dyskinesis can be caused by a whole range of factors, including upper cross syndrome and postural adaptations predisposing to it, neurological disorders. However, instrumental diagnosis of scapular dyskinesis is difficult, which makes the use of clinical tests the main method of its detection. In this lecture, the etiology of scapular dyskinesis, classification, diagnostic tests and treatment methods are analyzed in detail. The detection of scapular dyskinesis and its type determination in patients with shoulder joint pathologies allows us to form an optimal rehabilitation therapy protocol, including techniques of myofascial release, passive and active stretching of spasmodic and training of weak muscle groups aimed at correcting postural disorders, pathology of the scapulohumeral rhythm, restoration of the glenohumeral joint normal biomechanics.
