Scapula dyskinesia is broad term describing the alteration/ abnormal positioning of scapula due to alteration in dynamic movements. Several factors are responsible for such changes which includes anatomical malalignment of supporting structure such as malunion of clavicle fracture, thoracic kyphosis, instability of surrounding joints especially acromioclavicular joint instability, acromioclavicular joint arthrosis, derangement in glenohumeral joint etc. Various authors have suggested that abnormal muscle activity among scapular muscles further contributes to development of shoulder impingement. Altered muscles activity includes overactivity of trapezius muscle upper fibers, reduced or diminished activity of serratus anterior, reduced activity of lower trapezius muscles fibers hence such activities are responsible for alterations in position of scapula which further leads to development of scapula dyskinesia.
