Scapular dyskinesia is the alteration in the static and dynamic positioning of the scapula on the thorax. It is not an independent entity and is associated with other shoulder problems. Statistics has shown that its incidence to be 67% in cases of shoulder instability and 100% in cases of shoulder impingement. There are various means of scapular dyskinesis measurement. 3D measure analysis is considered   to be the gold standard. Number of  clinical tests have been developed but the problem is that dyskinesis may also be associated in asymptomatic patients also.  So it is important to distinguish whether it is a factor which is perpetuating   symptoms or not.  Tests like SRT (Scapular retraction  test ) and its refined version SRT (Scapular    repositioning test) has been found to have acceptable reliability. The  main purpose of these tests is to identify scapular dyskinesia in patients with shoulder pathology who can be helped by improving scapular muscle balance.
