Case studies: the suprascapular nerve and shoulder dysfunction*.
Since the initial symptoms usually include pain, an entrapment of the suprascapsular nerve may be mistaken for a shoulder disorder of musculoskeletal origin. However, upon examination, glenohumeral weakness during abduction, flexion, and external rotation with concomitant atrophy of the spinati muscles may be evident. Documentation is made with electroneuromyographic testing. Stretching the nerve is contraindicated; therefore, patients should be instructed to avoid activities which require scapular protraction and glenohumeral horizontal adduction. Furthermore, as the nerve heals, exercises to strengthen the weak muscles should be of benefit. J Orthop Sports Phys Ther 1985;6(4):254-258.
