Abstract
Vestibular compensation in patients with bilateral vestibular dysfunction was examined with the use of static posturography (SPG) and kinetic posturography (KPG). SPG was recorded by a stabilometer during quiet stance and KPG was recorded by POLGON so that angular changes of the shoulder in the frontal plane were measured during stepping in the same position. In addition, we recorded movements of daily life. The subjects were 3 patients with bilateral vestibular loss. The values of SPG decreased gradually. However, abnormalities of KPG with eyes closed tended to persist, and the effect of vestibular training was transient. In regard to movements of daily life, the jumbling phenomenon during walking disappeared within 6 to 8 months, but jumbling with quick head motion persisted. Unsteadiness while standing on a sofa, or putting on socks while standing on one leg, or walking in a dark room persisted.
