SYNOPSIS The responses to training of an autonomic relaxation response (peripheral vasodilatation) were studied. Forty migraine sufferers and forty controls were assigned to one of four treatments: (1) binary and analog feedback, (2) yoked (false) feedback, (3) relaxation‐tape induction, and (4) neutral‐tape control. The integral change of digital and extracranial blood volume was measured during one session. Responses of migraine sufferers were markedly different from normal subjects. No incremental utility of biofeedback over a simple relaxation procedure in the production of peripheral vasodilatation was found. High positive correlations were found between digital and extracranial blood volume changes.
