title: Cervicogenic headache, migraine, and tension-type headache. Pressure-pain threshold measurements.
abstract: Pressure-pain threshold (PPT) measurements were performed with a pressure algometer, at 22 specified points in the head in patients with cervicogenic headache (n = 32), migraine (with and without aura) (n = 26) and tension-type headache (n = 17). Comparisons were made with a group of healthy controls (n = 20). The average PPT differed significantly between the groups (ANOVA, F = 9.5, P < 0.0005), largely caused by the low threshold in cervicogenic headache patients. There were no significant differences between controls and the 2 other headache groups. In the cervicogenic headache group, the lowest PPT was found in the occipital part of the head on the side with pain predominance. The ratio between the dominant and non-dominant sides (all 11 points on each side) was 0.85 in cervicogenic headache, whereas it was 0.99 in migraine patients with side preponderance of the pain. The present results support the view that the pathogenesis of cervicogenic headache differs from that of migraine and tension-type headache. The results may further support the theory that fibres from the C2 level (innervating the occipital part of the head) may be included in the pathogenetic mechanism in cervicogenic headache.
