title: Biofeedback as therapy in Raynaud's disease.
abstract: The following dimensions of Raynaud's disease are reviewed: (a) etiological factors, particularly those of a psychological nature, (b) proposed biological mechanisms of vasospastic episodes, (c) efficacy of pharmaceutical and surgical interventions, and (d) use of biofeedback as therapy. Emotional stress appears to be wholly sufficient to induce vasopastic episodes in victims. Some authors further hypothesize that suppressed anger may be involved in the phenomenon. Vehicles proposed to account for the symptoms include local vascular pathology, sympathetic discharge, and biochemical phenomena. Sympathectomy does not produce permanent remission and vasodilator medications tend to have undesirable side effects even when successful. Documented success with feedback techniques is sparse but encouraging. Published outcome studies are often confounded by the use of additional treatment modes such as relaxation training and hypnosis. The study of Raynaud's disease has enormous potential for the understanding of psychosomatic illness in a holistic fashion. Stresses induce immediate physiological responses, and corrective conditioning is easily implemented and monitored.
