BVP-Biofeedback in the Treatment of Migraine

Abstract

Biofeedback training for self-regulation of blood-volume pulse ("BVP") amplitude of the temporal arteries has been used previously with good results in treatment of migraine headaches. In the present study, 23 subjects were randomly assigned to one of three groups and given (a) biofeedback training in temporal artery constriction and instructions to apply these skills during headaches; (b) the same training and instructions to apply the skills between headaches, during stress periods, and (c) biofeedback training to dilate the temporal arteries, and instructions to use these skills during stress periods. Clinically meaningful headache reductions were achieved and maintained at follow-up. Furthermore, results indicated that voluntary temporal artery dilatation also leads to headache reductions, and that there is a connection between levels of achieved self-regulation sldll and the clinical effects.
