Cognitive skills training versus EMG biofeedback in the treatment of tension headaches.

In an effort to study the role of cognitive skills training in the treatment of psychosomatic disorders, two single-case design experiments were conducted to assess the relative effectiveness of biofeedback procedures and cognitive coping techniques in the alleviation of tension headaches. For both subjects, biofeedback training influenced mean frontalis EMG levels, although such changes were not associated with concomitant reductions in headache activity. It was the presence or absence of cognitive skills training, however, that determined whether each subject reported changes in headache levels. These results suggest that a more efficient treatment approach for tension headaches would involve an increased emphasis on the modification of maladaptive cognitive activity. The present findings support the general view that a comprehensive approach in the treatment of stress-related disorders requires a concomitant focus on the cognitive, behavioral, and affective dimensions of the symptom. It was also suggested that biofeedback technology may be a useful tool for studying the physiological consequences of particular cognitive processes and in identifying particular cognitions with anxiety-provoking properties.
