During the descent of the Overhead Squat test, what combination of muscles might be overactive when abnormal asymmetric shifting of the cervical spine occurs?

The identified answer highlights a specific combination of muscles that can become overactive when there is abnormal asymmetric shifting of the cervical spine during the descent of the Overhead Squat test. This scenario often indicates an imbalance or compensatory pattern in the neck and upper body.

The sternocleidomastoid and scalenes are key muscles involved in the lateral bending and rotation of the cervical spine. If there is an asymmetrical shift in the cervical spine during the squat, these muscles may become overactive as they attempt to stabilize or support the head and neck in an abnormal position. Additionally, the levator scapulae is responsible for elevating the scapula and can become overactive when there is tension or strain in the cervical region. The upper trapezius also plays a role in scapular elevation and cervical motion and may contribute to the shift by exerting more force on one side, leading to asymmetrical positioning.

This combination of muscles is closely related to postural control and stability of the head and neck during functional movements like squatting. Recognizing this muscle pattern helps in designing corrective strategies that can help restore proper alignment and function to the cervical spine and surrounding musculature, ultimately improving overall movement patterns.
