The Scapular Assistance Test (SAT)
The scapula is the base on which all shoulder activities rest. Abnormal scapular motion has been implicated in different shoulder disorders. Scapular stabilization is often jeopardized in any shoulder injury due to pain inhibition which creates altered positioning leading to further pain.
The Scapular Assistance Test (SAT) test is designed to assess the contribution of scapular motion dysfunction to shoulder pain.
Scapular Assistance Test:
Practitioner places one hand on the upper trapezius muscle and the other hand on inferior medial scapular border. Patient is instructed to elevate arm while practitioner assists scapular upward rotation.
Positive Test: reduction in patient symptoms and impingement signs with arm elevation.
A positive test indicates scapular control is required as part of rehabilitation. Appropriate exercises early in the rehabilitation process for scapular control will provide optimal biomechanics leading to improved outcomes. The SAT is a simple clinical test that will identify those who would benefit from interventions aimed at improving scapular position.
