Effectiveness of biofeedback for treating migraine and tension headaches: a review of the evidence.

A review of the research reveals no evidence that finger temperature biofeedback training or temporal artery pulse biofeedback training is effective for treating migraine headaches. On the other hand, there is evidence that EMG biofeedback training is effective for treating tension headaches, but the EMG biofeedback training is not more effective than less complex and less expensive relaxation training. Reasons for the ineffectiveness of biofeedback training are discussed. The results of the controlled investigations are in sharp contrast to the prevailing beliefs and the results have a variety of implications.
