@bradleyblair83: Here you can see the rotator cuff muscle colored in brown. The rotator cuff is a group of muscles in the shoulder connecting the upper arm to the scapula. The rotator cuff provides stability to the shoulder. During a lying lateral raise, the rotator cuff muscles contribute to shoulder stability and controlled movement. As the arm moves away from the body, the supraspinatus assists in abduction while the infraspinatus and teres minor help manage external rotation, preventing excessive anterior translation of the humeral head. The subscapularis provides anterior stability, counteracting the pull of the posterior cuff muscles to maintain balanced joint mechanics. These muscles work together to keep the humeral head centred in the glenoid, reducing unwanted movement and allowing the larger deltoid to function more effectively throughout the lift. @Muscle and Motion #osteopathy #anatomy #shoulderpain #rotatorcuff
