摘　　要：目的探讨前庭自旋转试验(vestibular autorotationtext,VAT)对眩晕性疾病临床诊断的价值。方法对214例眩晕患者(眩晕组)和30例正常人(对照组)进行VAT水平、垂直测试。眩晕组按临床诊断又分为前庭中枢性疾病组、前庭外周性疾病组、非前庭性疾病组,比较各组特异性参数、非特异性参数的差异。结果眩晕组中VAT结果异常率为90.2%,与对照组(6.7%)比较差异有统计学意义(P%<0.01)。前庭中枢性疾病组水平增益增高明显高于其他组,差异有统计学意义(P<0.01);前庭外周性疾病组中水平增益降低明显高于其他组,差异有统计学意义(P%<0.01),其中21例伴有非对称性异常,临床均确诊为单侧病变。各组非特异性参数异常率差异均无统计学意义(P>0.05)。结论 VAT可以作为眩晕性疾病的一种筛查方法,也是定位诊断的一种客观检测手段。Objective To analyze the vestibular autorotation test（VAT）results in 214 patients with vertigo to evaluate the utility of VAT in clinical practice.Methods VAT was performed on 214 patients with vertigo（vertigo group）and 30 healthy controls（control group）.According to the clinical diagnosis,the vertigo group was divided into the central vestibular group,the peripheral vestibular group and the non-vestibular group.Results In the vertigo group and control group,abnormal parameters of VAT were shown in 193（90.2%）cases and 2（6.7%）cases,respectively（P 0.01）.The increased horizontal gains in the central vestibular group were significantly higher than those of other groups（P 0.01）.The decreased horizontal gains in the peripheral vestibular group were significantly higher than those of other groups（P 0.01）.Simultaneity,21 cases with abnormal asymmetry were found in the peripheral vestibular group.Those who were proven to have unilateral lesion by clinical practice were confirmed to have unilateral damage by the test.But there was no statistical significant difference in the results of the non-specific parameters among the three groups.Conclusion VAT can be considered as a method for the diagnosis of vertigo.VAT may be an objective mean for allocation of the damages that may cause vertigo.
