Q

what are causes of subacromial impingement syndrome

A

Intrinsic:
- muscle weakness (rotator cuff weakness > imbalanced forces > humerus rotates)
- hounder overuse (inflammation > reduced space)
- degenerative tendinopathy (acromium degeneration > cuff tear)

Extrinsic
- glenohumeral instabiklity
- anatomical variation
