Shoulder Impingement pain can be caused by muscle imbalances in the Shoulder Complex. Weak and shortened external rotator cuff muscles can be one of the contributing factors to this problem. When the Rotator cuff is strong and activates properly, it dynamically stabilizes the shoulder joint and allows for proper biomechanics to occur. To strengthen the external rotator cuff muscles position your elbow by your side, shoulders relaxed and your posture in spine neutral. Holding on to a resistance band use your other hand to help it out to the end range of external rotation. The opposite hand is doing all the work pushing the band outward that is being held by your other hand. Then let the hand holding the band slowly return to the start position. This is called Eccentric Strengthening because you’re strengthening the rotator cuff with a lengthening movement of the muscles. Repeat this for 10 repetitions, doing 3 sets daily.
