STUDY ON GAIT ABNORMALITY IN PATIENTS WITH VERIGO

应用新近研制的步态分析系统对眩晕患者的运动功能进行了评价，发现眩晕患者与对照组相比，站立位变异系数、眩晕患者在睁眼和闭眼自由步态中摆动和双支撑的幅度增大，站立时重心轨迹的规律性和站立时重心轨迹的规律性基本一致，足部压力进展的重叠图。闭眼步行时变异系数值增加的幅度更大，尤其是大的小脑桥脑角肿瘤。在足部压力进展期间，中枢性疾病的体重接受期比外周性疾病的体重接受期更不规则。单侧病变组患侧足底压力明显高于健侧，尤以闭眼行走时为甚。

By the use of newly developed gait analysis system, which has been employed for evaluation of locomotor function in patients with vertigo, the following things were found. When compared with control, coefficient of variation of stance, swing and double support became higher in free gait with eyes open and closed in patients with vertigo.Nearly the same tendency was obtained in regularity of trajectories of center of force during stance and overlapping figure of progression of foot pressure. As for the degree of increment of values of coefficient of variation became much higher under gait with eyes closed, especially in cases with large cerebello-pontine angle tumor. The period of weight acceptance during the foot pressure progression became much more irregular in cases with central disorders than that in cases with peripheral disorders. In addition, in cases with unilateral lesion foot pressure of the lesion side foot was more compared with that of the intact side especially during gait with eyes closed.
