Scapular Dyskinesis

Scapular dyskinesis refers to abnormal movement or positioning of the shoulder blade during arm motion. Rather than a diagnosis itself, it is a physical finding that underlies many shoulder pain syndromes, contributing to impingement, rotator cuff pathology, and shoulder instability. It is especially common in overhead athletes.

It is often caused by muscle imbalance, weakness, or poor posture. Overuse in sports or improper training can contribute. It may also develop after shoulder injury.

What are the symptoms?

Symptoms include shoulder pain, fatigue, and difficulty with overhead activity. Some people notice winging or abnormal movement of the shoulder blade. Performance may decrease in athletes.

How is it treated?

Treatment focuses on physical therapy to improve strength, coordination, and posture. Exercises target the shoulder blade muscles. Most patients improve without surgery.

When can I return to sports?
