Which area is affected by trapezius muscle injury?

Explanation:
The area affected by trapezius injury is the neck and the upper shoulder region. The trapezius runs across the upper back and into the neck, attaching to the skull, cervical spine, clavicle, and shoulder blade. It helps move and stabilize the shoulder blade and supports neck posture by assisting with head extension and rotation. When this muscle is injured, pain and dysfunction are most evident in the neck area and the upper back/shoulder girdle. The low back, hand, and knee aren’t directly controlled by the trapezius, so they aren’t the primary areas impacted. Therefore, the neck is the area affected.
