For a balanced scapulohumeral rhythm in arm elevation, it is necessary to have an optimal position, motion, stability and muscle performance of the scapula and scapular muscles. In the case of abnormal movements, so-called scapular dyskinesis, the tendons (e.g. biceps tendon, rotator cuff) can be irritated and may cause pain in overhead activity. There are various causes for scapular dyskinesis and, therefore, the treatment is a challenge for therapists. The aim of conservative treatment is to restore normal position and movement of the scapula and furthermore dynamic scapular stability during overhead activities. Rehabilitation based on effective exercises should be tailored individually and the complexity of the exercises should be increased slowly.
