We compared bedside tests of vestibulo-ocular function (head thrust and head heave signs) with caloric testing results in 68 patients with acute vestibular neuritis seen at onset and in follow-up for one year. The head thrust and head heave signs each were strong predictors of a decreased probability of recovery, and if both were present, there was a trend for a slower recovery and a further decrease in the probability of recovery. If the head thrust sign was absent, recovery was assured. Our results suggest that careful bedside testing of semicircular canal (head thrust maneuver) and otolith (head heave maneuver) function provides useful information for predicting prognosis in patients with acute vestibular neuritis.
