title: [Muscle tension of patients with tension headaches during and between episodes of pain].
abstract: The relationship between muscle activity and subjective pain in tension headache has been studied by comparing frontal EMG activity during and between headache episodes. Fifteen patients suffering from chronic tension headache were assessed during the course and outside headache episodes. These results suggest that there is no direct and constant relationship between muscle tension and pain in tension headache.
