Migraine and Headache Studies

The function of the current study was to examine the psychophysiological responses and response stereotypy of three groups of subjects—migraine headache, muscle-contraction headache, low frequency headache controls—during rest, stress and post-stress adaptation periods. Each subject was interviewed and then exposed to several experimental conditions: a 15-minute rest condition, two stressors (cognitive and physical), and a post-stress adaptation period following each stressor. Dependent measures included frontal electromyogram (EMG), forearm EMG, earlobe blood volume pulse amplitude and heart rate. The results of this study were consistent with some previous research in finding no differences in EMG levels between muscle-contraction and control subjects, a significantly greater activation in cardiovascular measures for migraine subjects, and evidence for response stereotypy in the migraine headache group.
