| Research Abstract |
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.
