Muscles use the scapula for attachment, enabling the flexibility and dexterity of the shoulder. Proper positioning and movement of the scapula is critical for full and normal shoulder range of motion. Abnormal movement of the shoulder blade is known as dyskinesis. The acronym SICK describes the state of shoulder when ...
