Hypnosis and biofeedback are cyberphysiologic strategies that enable subjects to develop voluntary control of certain physiologic processes for the purpose of improving health. Self-hypnosis has been used with and without biofeedback for a wide range of therapeutic applications, and both laboratory studies and clinical trials have shown it to be effective in improving symptoms and outcomes in various disorders. More formal Cochrane reviews of hypnotherapeutic interventions are currently under way. Thorough patient assessment should precede training in self-hypnosis in order to properly tailor training strategies to patient preferences and characteristics, especially for children. Workshops offered by various clinical societies are available to train health professionals in self-hypnosis.
