Clinical evaluation of static scapular posture in overhead athletes with asymptomatic shoulder injuries.

Background: Several etiologic factors have been postulated in overhead athletes according to their shoulder injuries, such as the scapular posture asymmetries. The measurement of the acromion border distance has been considered as reliable clinical test for evaluating the static scapula posture. The aim of this study was to quantify the differences in scapular posture between the dominant and non-dominant shoulders in two static positions in volleyball and swimmers athletes with asymptomatic shoulder injuries using the sliding calliper device.
