Compression at Myofascial Trigger Point on Chronic Neck Pain Provides Pain Relief through the Prefrontal Cortex and Autonomic Nervous System: A Pilot Study

Along with previous studies indicating a role for sympathetic activity in the exacerbation of chronic pain, the present results suggest that myofascial trigger point (MTrP) compression in the neck region alters the activity of the autonomic nervous system via the prefrontal cortex to reduce subjective pain.
