摘　　要：目的探讨前庭自旋转试验(VAT)对老年前庭源性眩晕的临床意义。方法把完成VAT检查的123例前庭源性眩晕患者按年龄分为老年组67例(≥60岁)和中青年组56例(<60岁),同期随机选取30例健康老年人作为对照组。比较入选者VAT各项指标的特异性和临床特点。结果老年组VAT异常率约占92.5%,明显高于对照组,差异有统计学意义(P<0.01)。老年组VAT≥2项指标异常率明显高于对照组,差异均有统计学意义(P<0.01)。老年组前庭中枢性损害、前庭中枢+外周性损害异常率明显高于青年组,差异有统计学意义(P<0.05)。结论 VAT是适合老年人的一种前庭源性眩晕检查的方法,有助于老年前庭源性疾病的定位诊断。Objective To study the clinical significance of vestibular autorotation test （VAT） for the diagnosis of vestibular vertigo in elderly people. Methods One hundred and twenty-three eld erly vestibular vertigo patients who received VAT were divided into ≥60 years old group （71--67） and 〈60 years old group （n=56）. Thirty healthy elderly persons served as a control group. Their VAT parameters were compared. Results The pencentage of abnormal VAT findings was 92.5% in ≥60 years old group,which was significant higher than that in control group （P〈0.01）. The incidence of central vestibular lesion and combined central and peripheral vestibular lesion was significantly higher in ≥60 years old group than in %60 years old group （P〈0.05）. Conclusion VAT is a reliable method for the diagnosis of vestibular vertigo in elderly people.
