▶️ Left shoulder dyskinesis. Before and after treatment assessments. Notice the down movement of the arm and shoulder blade on the left vs the right.
Simply put it’s the movement of the shoulder blade during arm motion, often caused by muscle weakness/imbalance, poor posture, or overuse, leading to pain, instability, and potential rotator cuff issues, treated primarily with physical therapy to improve muscle control, strength, and mechanics. It’s characterized by changes like the shoulder blade sticking out (“winging”) or a feeling of instability, and can affect overhead athletes or anyone with shoulder issues.
