Hi, I find that we have to go to the source of the problem to get results. Find the source of impingement. Why do we have an irritation of the Wikipedia reference-linkrotator cuff in the first place? Look at the glides of the G/H joint as well as the resting position of the humeral head in the glenoid cavity. Is there limitation of the inferior and posterior glides? Do we have a resting position which is anteriorly? There will be weakness of the cuff, no doubt but go to the source and don't get fooled by the obvious.
