The shoulder joint consist of the shoulder blade, the humerus, and many muscles and ligaments. The key muscles are the rotator cuff (supraspinatous, infraspinatus, subscapularis, and teres minor), scapula stabilizers (seratous anterior and low/mid traps), and the pec muscles. When these muscles become imbalanced limitations and injury can persist.
Shoulder pain occurs in nearly ¼ of the general population and shoulder impingement is the most prevalent diagnosis in these cases. Shoulder impingement is also called supraspinatus syndrome, swimmer’s shoulder, and thrower’s shoulder and occurs when the tendons of the rotator cuff muscles become irritated and inflamed as they pass through the joint. The rotator cuff muscles become compressed during movement and the body has to adjust to perform movements.
Symptoms of shoulder impingement are pain with raising arm from the side, weakness in lifting the arm, and loss of range of motion in the shoulder joint. This occurs due to incorrect repetitive motion and faulty posture. These faulty movements and postures tend to cause over-use of the pec muscles, levator scapulae, upper trap, and some of the supraspinatus. At the same time, weakness of the mid and lower trap occurs. These imbalance leads to increased faulty movement patterns of the shoulder and injury occurs.
Treatment for shoulder impingement consist of stretching, Active Release and/or Graston, and functional rehabilitation of the shoulder blade stabilizers, thoracic spine, and rotator cuff muscles.Tags: shoulder
