To obtain the normative values of vestibular evoked myogenic potential(VEMP),i.e.the threshold,latency,latency-interval,amplitude of healthy population in Tianjin medical university General hospital.These values will help clinical diagnosis.Seventy-five healthy individuals (39 males and 36 females,age from 21 to 70 years)were enrolled in this study.They were divided into 3 groups according to age:group 1(21-30 years),group 2(>30-50 years),group 3(>50-70 years).oVEMP and cVEMP were performed and the normative values were obtained.SPSS 19.0 was used to analyze the data.The response rate was 77.3% and 85.3% of oVEMP and cVEMP respectively in all subjects.The values of oVEMP:in group 1 response rate was 100%,amplitude was(8.29±1.25)μV and threshold value was(83.65±4.10) dBnHL.In group 2 response rate was 85.4%,amplitude was(6.32±1.21)μV and threshold value was(89.24±4.18) dBnHL.In group 3 response rate was 46%,amplitude was(4.26±1.20) μV,threshold value was(95.13±4.21) dBnHL.The values of cVEMP: in group 1 response rate was 100%,amplitude was(108.87±19.10)μV and threshold value was(84.54±4.35) dBnHL.In group 2 response rate was 83.3%,amplitude was(84.10±20.02)μV and threshold value was (90.33±4.29)dBnHL.In group 3 response rate was 72.0%,amplitude was(64.18±19.22)μV and threshold value was (95.19±4.30)dBnHL.The statistical analysis show significant difference in oVEMP/cVEMP response rate,threshold and amplitude among different age-groups(<0.05).No significant difference was found in N1,P1 latency and latency-interval among different age-groups(>0.05).The normative values of VEMP of healthy population in Tianjin medical university General hospital were obtained in this research.These VEMP data were used for the diagnosis of related diseases.
为获取天津医科大学总医院健康人群的前庭诱发肌源性电位（VEMP）的规范值，即阈值、潜伏期、潜伏期间隔、波幅。这些值将有助于临床诊断。本研究纳入75名健康个体（39名男性和36名女性，年龄21至70岁）。根据年龄将他们分为3组：第1组（21 - 30岁），第2组（>30 - 50岁），第3组（>50 - 70岁）。进行了眼震电图（oVEMP）和颈肌前庭诱发肌源性电位（cVEMP）检测并获得规范值。使用SPSS 19.0分析数据。所有受试者中oVEMP和cVEMP的反应率分别为77.3%和85.3%。oVEMP的值：第1组反应率为100%，波幅为（8.29±1.25）μV，阈值为（83.65±4.10）dBnHL。第2组反应率为85.4%，波幅为（6.32±1.21）μV，阈值为（89.24±4.18）dBnHL。第3组反应率为46%，波幅为（4.26±1.20）μV，阈值为（95.13±4.21）dBnHL。cVEMP的值：第1组反应率为100%，波幅为（108.87±19.10）μV，阈值为（84.54±4.35）dBnHL。第2组反应率为83.3%，波幅为（84.10±20.02）μV，阈值为（90.33±4.29）dBnHL。第3组反应率为72.0%，波幅为（64.18±19.22）μV，阈值为（95.19±4.30）dBnHL。统计分析显示不同年龄组之间oVEMP/cVEMP反应率、阈值和波幅存在显著差异（<0.05）。不同年龄组之间N1、P1潜伏期和潜伏期间隔无显著差异（>0.05）。本研究获得了天津医科大学总医院健康人群VEMP的规范值。这些VEMP数据用于相关疾病的诊断。
