Positive cVEMP asymmetry was defined as above 50% of IAD ratio or no response in unilateral side. Positive p-vHIT was defined as gain below 0.7 or presence of corrective saccade. Gray boxes show inter-test agreement (75.8%). Kappa value=0.559.
cVEMP, cervical vestibular evoked myogenic potential; p-vHIT, posterior canal plane of video head impulse test; IAD, inter aural difference.
