Plethysmographic Demonstration of Rapid Vasodilation by Direct Suggestion: A Case of Raynaud's Disease Treated by Hypnosis

Abstract

Abstract Raynaud's Disease is a painful vasospastic disorder of the fingers and toes precipitated by cold or emotional stimuli. Treatment has usually included protection from cold stimuli and vasodilators. Biofeedback, imagery, relaxation, and hypnosis have also been used. The relationship between response to treatment and hypnotizability has been inconclusive. A case of Raynaud's Disease was treated using hypnosis. The patient was highly hypnotizable and responded rapidly to direct suggestion with a fourfold increase in her blood volume. The implications of this rapid response and its relationship to hypnotizability are discussed with suggestions for further studies.
