The nerve also sends sensory information about touch, pain and temperature. When patients with neck pain have had deep cervical flexor muscle activation through sEMG it was found that analysis could determine less activation in these muscles when flexed and more activation in the superficial muscles, suggesting patients with pain alter their muscle activation, which may be another way to consider the physiology of pain.15 Variation of activation and inactivation may be explained by pain adaptation theories that suggest agonist muscles have reduced activity during pain whereas opposing muscle group activities increase.16,17.
