This study will be conducted to investigate the relationship between scapular dyskinesia and rotator cuff muscle strength and acromiohumeral distance in asymptomatic individuals.

When the scapula moves in an abnormal way, a condition known as scapular dysfunction (SD) occurs, leading to shoulder pain and dysfunction. It is possible for patients with SD to experience no symptoms at all. SD symptoms can include a combination of the following anterior shoulder pain, Posterosuperior scapular pain, Superior shoulder pain, shoulder impingement syndrome, rotator cuff dysfunction, and shoulder instability.Things like early scapular elevation, abrupt downward rotation, and a prominent medial edge and inferior angle of the scapula are seen during shoulder motions. It has been suggested that impaired scapulothoracic musculature function might lead to changes in shoulder kinematics, which in turn can increase the risk of injury.Individuals with SD often experience pathologies such as scapula-humeral rhythm disturbance, glenoid labrum difficulties, glenohumeral instability, rotator cuff syndrome, subacromial impingement syndrome, and glenoid labrum abnormalities. In individuals suffering from RC tendinopathy, a decline in RC muscle performance is associated with lower health-related quality of life and patient-rated function. In order to determine which patients with scapular dyskinesis may benefit most from a rehabilitation program aimed at enhancing muscular performance, clinicians may find it useful to gather data on shoulder strength. A portable dynamometer is an easy, cheap, and valid way to get these kinds of data. to fill that gap in literature by Finding an association between scapular dyskinesia and the acromiohumeral distance and rotator cuff muscle strength in individuals with asymptomatic scapular dyskinesia
