Scapular Dyskinesis

Optimal shoulder function and health rely on the coordination of all shoulder muscles. When this balance is disrupted, it leads to an abnormal strain on the rotator cuff, known as "Scapular Dyskinesis." Let us help you maintain proper shoulder motion and prevent discomfort—trust our expertise for a healthier, pain-free shoulder.

About Scapular Dyskinesis

Your shoulder’s complex structure consists of three bones—the scapula (shoulder blade), clavicle (collar bone), and humerus (long arm bone)—forming a shallow ball & socket joint that relies heavily on surrounding muscles for support. To maintain proper function and shoulder health, these muscles must work harmoniously together. Any disruption in normal shoulder motion creates an abnormal strain on the rotator cuff, referred to as “Scapular Dyskinesis,” characterized by an irregular shoulder movement.

Scapular Dyskinesis is a functional condition that can lead to structural problems, often related to upper crossed syndrome—a pattern of alternating tightness and weakness in the neck and shoulder muscles.

The progression of upper crossed syndrome often begins with tightness in the pectoral muscles, often caused by overtraining or poor posture seen in desk workers. This tightness results in a stretching and weakening of the muscles that stabilize the scapula, causing the shoulders to roll forward.

To understand this better, think of the opposing movement of bicep and tricep muscles. Similarly, when hunched over a desk, the pectoral muscles flex or shorten, causing the scapular muscles to relax and adapt to that position. Over time, this continuous relaxation leads to weakness, impairing the proper stabilization of the shoulder blade during movement.

At our clinic, we are committed to addressing these issues and providing comprehensive solutions to restore proper shoulder function and stability. Don’t let shoulder discomfort hinder your daily life; let us help you achieve a healthier and pain-free shoulder through our specialized care.
