Document Summary
Sai decreased subacromial space: subacromial bursa, supraspinatus tendon, tendon of the long head of biceps. Tendons have slow degenerative process not noticeable at first. Athlete presentation: pain location under acromion, lateral (supraspinatus)and anterior (long head of biceps) aspect, bursa spread and affects even, aggravating roms. Coordination of muscles of humerus and scapula to optimize: painful arc subacromial space. Instead of outer ranges and end of ranges. Mechanics aren"t working well to cause pinch. Abduction ~60 degrees in pain starts, better at top. Mechanical themes: glenohumeral, superior migration: humerus, limited lr, scapular, superior rotation is decreased. If you retract shoulder can only raise arms a certain amount - normal: anteriorly tilted. Bring acromion down over humerus a bit. Forward: any one of these issues can reduce space and result in impingement, often have combination of these features. Eccentric strength and control: gh lateral rotators.
