Abstract

OBJECTIVES

To determine the sensitivity and specificity of the head-shaking nystagmus test (HSN), the nystagmus elicited in response to a vigorous rotation of the head in the horizontal plane, in the study of patients with peripheral unilateral vestibular disease.

PATIENTS AND METHODS

Retrospectively, we analyze the relationships between the HSN and the rest of the videonystagmographic tests on eighty-three patients with peripheral unilateral vestibular disease.

RESULTS

Twenty-three patients showed a positive head-shaking nystagmus; twenty-one of them had unilateral caloric hypofunction and only two had a symmetric caloric test, but both of them showed some type of vestibular dysfunction on other videonystagmographic test. In our series, the HSN sensitivity for the existence of peripheral vestibular disease was 48.8%, while the specificity was 95% in relation to the caloric test, reaching 100% when the gold standard was the presence of any abnormal videonystagmographic test.

CONCLUSION

HSN is a simple test that can be useful to identify patients having unilateral vestibular hypofunction.

摘要

目的

在单侧外周性前庭疾病患者的研究中,确定摇头性眼震试验(HSN)(即头部在水平面剧烈旋转时诱发的眼震)的敏感性和特异性。

患者与方法

我们回顾性分析了83例单侧外周性前庭疾病患者的HSN与其他视频眼震图检查结果之间的关系。

结果

23例患者出现阳性摇头性眼震;其中21例有单侧冷热试验功能减退,仅2例冷热试验结果对称,但这2例在其他视频眼震图检查中均显示某种类型的前庭功能障碍。在我们的研究系列中,HSN对于外周性前庭疾病存在的敏感性为48.8%,相对于冷热试验,其特异性为95%,当金标准为任何异常视频眼震图检查结果时,特异性达到100%。

结论

HSN是一项简单的检查,可用于识别单侧前庭功能减退的患者。
