Utility of headshake versus whole-body vor evaluation during routine electronystagmography

摘要: Evaluation of the vestibulo-ocular reflex (VOR) by caloric testing yields important localizing information, but does not examine entire frequency spectrum vestibular function. With addition head rotation at 0.5 Hz (50 deg/s) and a velocity sensor to measure movement, additional unique information regarding higher VOR function can be readily obtained using standard electro-oculography (EOG). Over past 4 years, active head-on-body passive whole-body with four-channel strip-chart recording hand analysis have been routinely performed on every patient referred for
