Any abnormality of the shoulder blade (scapula) position can result in secondary effects on the function of the shoulder joint. For instance, if the shoulder blade tilts anteriorly and laterally, the space available for the rotator cuff may be narrowed, resulting in tendon abrasion and injury, known as shoulder impingement syndrome.
Scapular stabilization refers to a set of exercises that strengthen the shoulder girdle muscles to restore normal shoulder blade motion and position. A great exercise to perform would be the Shoulder Blade Squeeze.
