Mean VOR gain in the VS group, was significantly lower on the affected
side in the three canal planes (p=0.08, p=0.00 and p=0.01 for
horizontal, posterior and superior semicircular canal, respectively)
when both case and control groups were compared. Refixation saccades in
the affected horizontal canal had a significantly higher latency and
velocity in the VS group (p=0.0001). (Table 1).
Categories were then established for the variables VOR gain, latency,
and velocity of the saccades, to determine the best model for predicting
the probability of VS. (Table 2).
