STUDY ON GAIT ABNORMALITY IN PATIENTS WITH VERIGO

使用新开发的步态分析系统对眩晕患者的运动功能进行评估，发现以下几点。与对照组相比，眩晕患者睁眼和闭眼自由步态的站姿、摆动和双支撑变异系数增大，站立时重心轨迹的变化规律和足底压力的变化规律基本一致。闭眼步态下变异系数增加的幅度较大，尤其是桥小脑角较大的肿瘤。中枢性疾病患者在足底压力进展过程中的体重承受期比外周性疾病患者更加不规则。此外，单侧病变足的患侧足部压力明显高于健侧，尤其是闭眼行走时。

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.
