We studied the effects of electromyographic biofeedback on measures of asthma severity in children. Fifteen children received biofeedback training to reduce facial tension, and 14 children, who served as controls, received biofeedback training to maintain facial tension at a stable level. Assignment to experimental condition was random. As a result of training, electromyographic levels decreased in children trained in facial relaxation and remained fairly constant in children trained in facial tension stability. Biofeedback training was augmented for children in both groups by having them practice their facial exercises at home. Each child's condition was followed for a five-month period subsequent to biofeedback training. Throughout the experiment, the following measures of asthma severity were monitored: lung function, self-rated asthma severity, medication usage, and frequency of asthma attacks. In addition, standardized measures of attitudes toward asthma, self-concept, and chronic anxiety were recorded at regular intervals. As compared to the facial stability subjects, the facial relaxation subjects exhibited higher pulmonary scores, more positive attitudes toward asthma, and lower chronic anxiety during the follow-up period. Subjects in the two groups, however, did not differ on self-rated asthma severity, medication usage, frequency of asthma attacks, or self-concept. Based on the improvements we observed in pulmonary, attitude, and anxiety measures, we concluded that biofeedback training for facial relaxation contributes to the self-control of asthma and would be a valuable addition to asthma self-management programs.

Behavioral treatments (relaxation, biofeedback, cognitive-behavioral therapy) have been empirically validated for migraine and tension-type headaches, with recent meta-analyses yielding 37% to 50% reductions in tension-type headache, comparing favorably with 33% reduction from medication prophylaxis (amitriptyline). Research has moved toward increasing availability and cost effectiveness through alternative delivery formats and combining and comparing them with standard medications. Further modifications would make standard behavioral treatments available and conducive to primary care settings where most patients receive treatment. Beyond the current behavioral and drug treatments, we propose a fundamental shift in conceptualization and treatment for headache.
