Background and Objectives We evaluated the correlation between video head impulsetest (vHIT) and dizziness handicap inventory (DHI), which is commonly used to quantify severityof dizziness in vestibular neuritis (VN). Subjects and Method Twenty VN patients undergoing vHIT either at the acute or follow-upstages of treatment were assessed by DHI questionnaire. Gain and gain asymmetry (GA) werecorrelated with DHI scores and abnormal vHIT rates were compared according to the severityof dizziness (mild ≤30; moderate-to-severe ≥32). Results vHIT gains significantly increased from the acute to follow-up stages (from 0.45±0.18 to 0.70±0.25), whereas GA and DHI scores decreased (GA, from 0.36±0.15 to 0.22±0.18;DHI scores, from 35±26 to 23±23). Although vHIT gains or GA showed no correlation withDHI scores at the acute stage, vHIT gains showed significant correlation with DHI scores atthe follow-up (R-sq=0.32, p=0.01) stage. vHIT gains and GA did not differ according to theseverity of dizziness during the acute stage; however, vHIT gains (0.78±0.25) of patients withmild dizziness were significantly higher than those (0.51±0.14) with moderate-to-severe dizzinessat the follow-up stage. During the follow-up, all patients with moderate-to-severe dizzinessshowed abnormal vHIT gain, but 43% of patients with mild dizziness showed abnormalvHIT gain, showing a significant difference (p＜0.05). Conclusion Reduced vHIT gain was significantly correlated with high degrees of dizzinessat the follow-up, but not at the acute stage, suggesting that high-frequency canal dysfunctionis contributed in part by the subjective dizziness at the follow-up. Our findings suggest thatvHIT might give an indirect evidence for implementing vestibular rehabilitation for enhancingimpaired vestibular function and relieving subjective dizziness.
