青年人前庭自旋转试验的正常值

目的了解健康青年人的前庭自旋转试验(VAT)的正常值。方法采用美国WSR公司的VAT检测仪对31例20～30岁健康青年人进行VAT检测,统计分析其实际测量值,并与检测仪自身的正常参考值范围相比较。结果20～30岁健康青年人的VAT的实测值基本都在参考范围之内。2.0、2.3、2.7、5.5、5.9Hz的水平增益实测值,2.0、5.9Hz的垂直增益实测值,以及2.0、2.3、2.7、3.1、3.5、3.9Hz的垂直相移实测值与参考值相比差异具有显著性(P<0.05);在水平相移和非对称性中,实测值与参考值相比差异均无显著性。结论健康青年人的VAT正常值在参考范围之内,青年人的前庭功能在较低频率范围(2～3Hz)可能更敏感。

Normal Values of Vestibular Autorotation Test in Young People

Objective To explore the normal values of vestibular autorotation test(VAT) in young people.Methods VAT was performed in 31 young people aged 20-30 years.The measured value were analyzed and compared with the reference normal value.Results The measured values of VAT in healthy young people are almost within the normal range of the general population.Compared with the reference normal values,the horizontal gains at 2.0,2.3,2.7,5.5,and 5.9 Hz,the vertical gains at 2.0 and 5.9 Hz,and the vertical phases at 2.0,2.3,2.7,3.1,3.5,and 3.9 Hz were significantly different(P<0.05).No significant difference was shown in the horizontal phases and asymmetry.Conclusions The normal values of VAT in young people is within the reference normal range of the general population.The vestibular function of young people may be more sensitive in lower frequency range(2-3Hz).
