人体姿态平衡仪在眩晕患者诊断中的应用

The clinical application or posturography in the diagnosis of the patients with vertigo

摘 要：目的 研究人体姿态平衡仪在眩晕患者诊断中的应用，为鉴别前庭中枢性眩晕和周围性眩晕提供帮助。方法 采用人体姿态平衡仪，测试了71例正常人及185例中枢与末梢性眩晕患者的姿势图及有关参数。结果 将各年龄组正常人的参数进行比较，30岁组平衡功能最佳，与50岁以上组相比有显著性差异；正常人的人体重心晃动轨迹的图形为中心型，中枢性眩晕以弥散型多见，末梢性眩晕介于两者之间；正常人与患者各参数比较，眩晕患者晃动的轨迹长，速度快，差异有显著性，中枢与末梢性眩晕组间的参数差异于显著性。结论50岁以后前庭功能开始减退，人体姿态平衡仪可用以对眩晕患者进行粗筛。

Abstract: Objective To evaluate the clinical application of posturography in the diagnosis of the patients with vertigo and the differentiation in central and peripheral vertigoes. Methods The parameter was measured with posturography during 1 minute period in 71 normal subjects and 185 patients suffering from central and peripheral vertigoes. Results The length of locus was the shortest and velocity of sway was the slowest in the 30-year group. The difference between 30-year and 50-year was more significant (F<0. 01);Centripetal pattern was the most prominent figure pattern in the normal subjects,and diffuse pattern was the most prominent figure pattern in the central vertigoes ; Length of locus and velocity of postural sway of the patients were significantly increased in comparision with normal subjects. There were no difference in central and peripheral vertigoes. Conclusion The decline of vestibular function start from 30-year. The posturography can discern the central vertigoes from the peripheral roughly.
