R1 and R2 blink reflex latencies were investigated blind in 10 patients with cervicogenic headache, 11 patients with chronic tension-type headache, 11 patients with migraine, and 9 headache-free controls. There were no R1 or R2 latency differences between the four groups. The latency of R1 increased significantly with headache duration in tension-type headache patients. Shorter R1 latencies were found on the symptomatic side than on the non-symptomatic side in cervicogenic headache patients. The results suggest that a state of hyperactivity may be present in the ipsilateral trigeminal nucleus in cervicogenic headache. Hypoactivity, however, may develop over time in tension-type headache.
对10例颈源性头痛患者、11例慢性紧张型头痛患者、11例偏头痛患者和9例无头痛对照者进行了R1和R2眨眼反射潜伏期的盲法研究。四组之间R1或R2潜伏期无差异。在紧张型头痛患者中，R1潜伏期随头痛持续时间显著增加。在颈源性头痛患者中，症状侧的R1潜伏期比无症状侧短。结果表明，颈源性头痛患者同侧三叉神经核可能存在活动亢进状态。然而，紧张型头痛可能会随着时间的推移而出现活动减退。
