Central compensation of central vestibular lesions

Aims: Peripheral and central vestibular lesions cause a vestibular tone imbalance, which is centrally compensated. Whereas central compensation of peripheral vestibular lesions is already studied in detail, little is known about central compensation of central lesions. The subjective visual vertical (SVV) – as a component of the ocular tilt reaction – is a useful psychophysical parameter to measure central compensation for two reasons: first, it deviates in most acute peripheral and central vestibular lesions and, second, it normalizes over time despite persisting vestibular deficits. Objective: To determine the…
