A new evaluation of vestibular compensation.

Vestibular compensation process in six patients was examined by means of static (SPG) and kinetic posturography (KPG). SPG was recorded by a stabilometer during standing and KPG was recorded by POLGON so that angular change of shoulder in the frontal plane was measured during stepping. The subjects included three cases with vestibular neuronitis, three cases with bilateral vestibular loss. In vestibular neuronitis, SPG improved earlier than KPG. As a result of vestibular training, initial high levels of SPG and KPG fall precipitously and in the case with sequela, a remarkably high level of KPG gradually decreased. In bilateral vestibular loss, abnormality of KPG tended to persist and those results would be due to the disappearance of a hip strategy. The effect of training upon the case which started from the early days was not shown. However, the case which started from 10 months after the onset showed remarkable improvement of SPG and KPG.
