Document Summary
Dynamic stabilizers: rotator cuff: subscapularis, supraspinatus, infraspinatus, teres minor. Move shoulder through rom: abduction supraspinatus internal rotation subscapularis, external rotation infraspinatus teres minor. Sudden onset usually minor grade i twinge felt in the shoulder some limitation in function positive sttt (selective tissues tension testing) what will we see: muscle is sore when we contract or stretch it. Drop arm test: used with a total cuff tear and emphasis on supraspinatus. Won"t be able to hold arm at 90 degrees. Rotator cuff strains and tears: other athlete (>35-49 years) Really a tendinosis because of career or posture, rotator cuff rubs and breaks down (chronic changes and frays until in degenerates. Weakness of rotator cuff muscles reduces the effectiveness of centralization of the humeral head. With impingement, humerus pulled too far up and pinches the supraspinatus or subacromial bursa. This causes pain during rom between 70-120 degrees. Diffuse pain around acromion and over deltoid.
