Biofeedback for headache.

Biofeedback has proven effective in treatment of vascular and muscle contraction headache. However, many factors have not yet been explored. Research into personality and psychologic aspects that can predict success or failure with biofeedback is necessary, as is research into the applicability of skills learned in the laboratory to nonlaboratory situations. The possibility of symptom substitution should be investigated, and the problem of using study volunteers who do not adequately represent the headache population must be dealt with. Biofeedback represents a significant step forward in control of migraine and muscle contraction headache. Further experience with biofeedback techniques is necessary, but the future seems to promise continued success with this new method of treatment.
