摘要
目的:探讨电刺激所诱发的瞬目反射(BR)的不同检测方法和波形特征,进行定量分析,建立其实验室参考值。方法:采用神经肌电图仪对30例(60侧)健康年轻志愿者进行眶上神经及颏神经刺激,分别于眼轮匝肌及提上唇肌处记录瞬目反射波形,统计4组瞬目反射的R1、R2、R2’的潜伏期及波幅,并做出统计学处理。结果:眶上神经刺激眼轮匝肌记录方法,即常规瞬目反射测试方法所得结果与既往国内外文献报道基本一致,眶上神经刺激提上唇肌记录方法可引出与前法类似波形,且图形稳定,重复性好。颏神经刺激眼轮匝肌及提上唇肌记录方法引出之波形中,R1欠稳定,但双侧R2稳定。结论:采用眶上神经刺激提上唇肌记录方法可作为瞬目反射的检测方法之一。颏神经刺激眼轮匝肌及提上唇肌记录方法,与眶上神经刺激眼轮匝肌或提上唇肌记录方法相结合可作为瞬目反射的辅助检测。
Objective：To investigate the different techniques and wave characteristic of applying non-invasive stimulation in blink reflex.Methods：Thirty volunteers participated in this study.Using the electrodiagnostic techniques,the orbital nerve and mental nerve were stimulated and the waves were respectively recorded at orbicularis oculi and levator labli superioris,then concluded the latency and amplitude of R1,R2,R2＇.Results：The results of blink reflex were basically identical with the normative criteria.The wave of stimulating the orbital nerve and recording at levator labli superioris resembled BR.The images were steady and repeatable.The waves of stimulating mental nerve and recording at orbicularis oculi and levator labli superioris were unstable and partial R1 absent.Conclusion：The techniques of stimulating orbital nerve and recording at orbicularis oculi and levator labli superioris are valuable in the initial investigation of trigemino-facial reflex.The techniques of stimulating mental nerve and recording at orbicularis oculi and levator labli superioris can be used to examine assistantly.
