摘要

摘要: 目的: 探讨不同年龄组正常人群颈肌前庭诱发肌源性电位(cVEMP)及眼肌前庭诱发肌源性电位(oVEMP)的差异及临床意义。方法: 纳入60例健康人,其中20~40岁20例,41~60岁20例,60岁以上20例。采用短纯音刺激方式,对研究对象进行前庭诱发肌源性电位检查。采用SPSS 16.0软件进行统计分析。结果: 随着年龄增加,cVEMP中P1波潜伏期延长,P1-N1振幅下降,振幅不对称比增加;oVEMP中N1波潜伏期延长,N1-P1振幅下降,振幅不对称比增加。结论: 随着年龄老化,耳石器反射通路时间延长、耳石器功能呈下降趋势且两侧下降程度不一致。

Abstract: Objective: The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people.Method: Sixty normal subjects were recruited for the vestibular evoked myogenic potential exam ination. Among them, 20-40 year-old group was setted as the first group,41-60 year-old group was setted as the second group,>60-year-old group was setted as the third group.Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data.Result: As the age growing,P1 latency prolonged,N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged,P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP.Conclusion: With the age growing,the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.
