Abstract
The amplitude of temporal artery pulsation was monitored at rest, after standing from the sitting position and after exercise in 23 normal controls, 10 patients subject to chronic tension headache and 107 migrainous patients. The pulses of migrainous patients did not differ from normal at rest or on standing. On exercise, the temporal artery on the habitually affected side of migrainous patients dilated more than the headache-free side, while exercise-induced changes in tension headache patients were less than those in normal controls. The responses were not influenced by previous or current medication.
