The blink reflex - a simple, non-invasive and inexpensive test - may be indicative of lesions or dysfunctions of the brainstem, and particularly assesses the trigeminal-facial arch. Results from alterations of the blink reflex in patients with headaches have provided controversial data.
Registration of the waves R1 and R2 (ipsilateral to the stimulus) and R2c (contralateral to the stimulus) by electroneuromyography.
A large number of controls (n=160) and patients with chronic migraine (n=160) were studied. No significant differences were observed between the two groups.
It is possible that this relatively simple and primitive reflex is not affected unless there is significant damage to the brainstem.
瞬目反射——一种简单、无创且廉价的检查——可能提示脑干病变或功能障碍，尤其可评估三叉神经-面神经弓。头痛患者瞬目反射改变的结果提供了有争议的数据。
通过肌电图记录R1和R2波（刺激同侧）以及R2c波（刺激对侧）。
研究了大量对照者（n = 160）和慢性偏头痛患者（n = 160）。两组之间未观察到显著差异。
除非脑干有严重损伤，这种相对简单和原始的反射可能不会受到影响。
