Document Summary
Examine mechanics consider your coin choose exercises. Anterior humerus: too far forward due to instability, opportunity for impingement. Superior humerus: comes up too high, causes impingement. Gird: gh int rot deficiency, too much laxity in external but not enough internal rot, posterior internal impingement. Limited lr: important for raising arm overhead b/c moves greater tuberosity out of the way, helping us preserve subacromial space reduce pressure within that space. Eg. limited lr: too much pull from medial rotators pec major, lat dorsi, too little from lateral rotators infra teres minor. Excess protraction: forward shoulder posture scaps come forward and protract excessively, endup crushing things, need opens shoulder, need to open things up holding you in this position protractors, strengthen retractors. Limited superior rotation: scapular dyskinesis type iii, shrug too much b/c don"t rotate well, need less from shruggers, less levator scap and upper traps, more superior rotation from lower traps + serratus. Excess anterior tilt: scapular dyskinesis type i.
