Use of active head movements for computerized vestibular testing.

摘要: • The vestibulo-ocular reflex (VOR) is seldom tested above 2 Hz, in spite of the higher-frequency components that stimulate it during natural head movements. We horizontal VOR ten normal subjects 18 s active, side-to-side motion over a frequency range from to 6 Hz. Audible clicks were used as linearly increasing cue. Head velocity was monitored. two experimental conditions movement while fixating stationary wall-mounted target dim light, and darkness with an imagined target. Computed gain phase results test not significantly different, due inactivation smooth pursuit system conclude responses can be light by brief, low-cost test, which does require expensive rotating machinery.
