Effect of Biofeedback Treatment on Sympathetic Function in Common Migraine and Tension-Type Headache

Abstract

Behavioral therapies such as biofeedback are commonly used to treat migraine and tension headache. Controlling sympathetic activity is effective for controlling the pain in both disturbances. A group of 26 common migraine patients and a group of 14 tension headache patients were treated by electromyographic biofeedback (EMG-BFB); blood samples were collected during the treatment (1st session; pre and post 10th session) and plasma catecholamines and cortisol measured to determine basal levels and changes induced by the behavioral therapy. The clinical efficacy of BFB treatment for tension headache and common migraine was confirmed. The basal values of the plasma stress indices were significantly different between the two groups, but did not change during treatment. The lack of correlation between the clinical improvement and the biological indices monitored indicates the need for further studies with standardized protocols in order to probe the mechanism of action of these effective behavioral therapies.
