Document Summary

Clinical inspection of shoulder injuries scapulothoracic rhythm. 120 o from gh movement and 60 o from scapular rotation. Scapular winging serratus anterior weakness or long thoracic nerve pathology. As a group the rc internally and externally rotates the humerus and compresses and centralizes the humeral head in the glenoid fossa, limiting extraneous movement and maintaining optimal biomechanical efficiency. Supraspinatus external rotation, stabilization of humeral head, abduction. Infraspinatus external rotation, cross extension, stabilization of the humeral head. Subscapularis internal rotation, stabilization of the humeral head. Selective tissue test: drop arm test for rotator cuff tendinopathy. Procedure humerus is fully abducted, patient slowly lowers the arm to the side. Positive findings arm falls uncontrollably from a position of approximately 90 o abduction, severe pain. Implications inability to lower the arm in a controlled manner is indicative of lesions to the rotator cuff, especially ss. Selective tissue test: gerber lift-off test for subscapularis pathology.
