正常人瞬目反射的测试与分析

The influences examination and analysis of blink reflex in normal volunteer

目的:研究正常人瞬目反射(BR)的影响因素并探讨其在耳鼻咽喉科临床应用价值。方法:采用Medtronic Keypoint神经电生理仪,检测60例正常人瞬目反射的各项指标。结果:正常人瞬目反射的各波潜伏期分别为R1(10.27±0.91)ms、R2(28.79±4.08)ms、R2′(29.06±4.35)ms;R1、R2、R2′波各自潜伏期侧别差异无统计学意义(P>0.05);男性受试者R1波潜伏期较女性延长(P<0.05),男性R2和R2'波潜伏期均较女性显著延长(P<0.01);男性R1波潜伏期与受试者年龄呈正相关(P<0.05),R2和R2'波潜伏期与受试者年龄无相关关系(P>0.05);女性BR各波潜伏期与受试者年龄均无相关关系(均P>0.05)。结论:瞬目反射各波的潜伏期可受年龄、性别等因素的影响,临床应用时有必要建立不同人群的正常参考值。

Objective：To study the influence factors on latent values of blink reflex （BR） in normal volunteer. Method： BRs of 60 normal volunteers were detected bilaterally with Medtronic Keypoint EMG. Result：The normal values of BRs＇ latencies in our research was R1 （10. 27 ± 0. 91） ms, R2 （28. 79 ± 4. 08） ms and R2＇ （29. 06 ±4.35）ms, respectively. There was no statistical difference between left ear and right ear, as far as the latencies of R1, R2 and R2＇were concerned respectively（ P 〉0.05）. The latency of R1 in male was more prolonged than female（ P 〈0.05）, as well as the R2 and R2 in male prolonged significantly（ P 〈0.01）. Furthermore, the latency of R1 has a positive relation with age（ P 〈0.05） in male group, while the latencies of R2 and R2＇have no relation with age（ P 〉0.05）. Lateneies of BR in female have no relation with age（ P 〉0.05）. Conclusion： To some extent, age and gender have some influence on the latencies of BR. It is important to establish normal values about BR in different age or gender of people.
