摘要
目的研究正常人重心动摇检查的特征,探讨重心动摇检查对眩晕患者的诊断价值。方法采用日本Ani-ma公司生产的EAB-100型重心动摇仪对112例正常人、72例周围性眩晕患者及30例中枢性眩晕患者进行重心动摇检查,检测指标包括动摇类型、总轨迹长、动摇面积、重心动摇平均中心偏位、闭目直立率,比较组间指标的差异。结果正常人重心动摇类型分为中心型、弥漫型、前后型、左右型及多中心型5型,以中心型为主,中枢性眩晕以弥漫型为主,周围性眩晕介于二者之间。正常人闭眼时总轨迹长、外周面积、矩形面积、单位面积轨迹长与年龄存在线形回归关系(P<0.05),性别间各项指标的比较差异均无显著性。眩晕组患者重心动摇的总轨迹长、动摇面积均较正常组显著增大(P<0.0167);无论睁眼或闭眼,中枢组患者外周面积、矩形面积均较周围组显著增大(P<0.0167);闭目直立率在正常组与眩晕组之间差异无显著性。结论动摇类型对于眩晕的病因有一定价值;总轨迹长及外周面积对眩晕患者敏感性较高,有助于眩晕症的诊断;年龄是影响人体平衡功能的重要因素;性别与平衡功能无相关性;视觉对于维持人体平衡功能具有重要意义。重心动摇仪对于评定人体平衡功能状况有一定价值,重心动摇检查可作为对眩晕、平衡障碍患者的辅助诊断方法。
Objective To study the characteristics of the normal subjects with postural sway test and discuss the value of postural sway test in the diagnosis of dizzy patients. Methods Totally 112 normal subjects, 72 patients with peripheral vertigo, and 30 patients with central vertigo were examined using a stabilometer （EAB-100, Anima Co. , Japan）. Items include patterns, length of locus, envelope area, deflection average center displacement, and romberg rate were recorded and compared. Results The postural sway was classified into the following five patterns ： centripetal, forward and backward, right and left, diffuse, and muhicentric. Centripetal pattern was the most prominent figure pattern in the normal subjects, while diffuse pattern was the most prominent figure pattern in the patients with central vertigo. When the normal subjects closed their eyes, age was linearly correlated with the length of locus, envelope area, rectangel area, and unit area path length （ P 〈 0.05 ）. Sex was not correlated to all of these parameters. The length of locus and envelope area in the patient groups were significantly increased when compared with the normal subjects （ P 〈 0. 0167 ）. Romberg rate was not significantly different between the patients and the normal subjects. Conclusions The pattern of postural sway is useful for the diagnosis of vertigo. Age is an important factor that affects the balance function. Sex seems has no influence. Visual input plays an important role in maintaining postural balance. Stabilometer is a useful tool for evaluating balance function, and postural sway test may be a valuable assistant examination.
