Relationship of bHIT sensitivity to the VOR asymmetry and absolute VOR gains in unilateral vestibulopathy and bilateral vestibulopathy. Subgroup analysis of patients with unilateral vestibulopathy (n = 43) and bilateral vestibulopathy (n = 38). (A) The bHIT sensitivity increased with increasing VOR asymmetry between the 2 labyrinths. (B) The bHIT sensitivity increased with increasing degrees of unilateral hypofunction. (C) When both labyrinths had severe VOR gain reductions, the bHIT had the highest sensitivity. The bHIT sensitivity was most dependent on the VOR asymmetry in the group with dissimilar gains (“all other combinations”).
