ABSTRACT
Objective:
To explore the correlation between the parameters of video head impulse test ï¼vHITï¼and dizziness handicap inventory ï¼DHIï¼ score in patients with vestibular neuritis.Methods:
Clinical data of 46 patients with vestibular neuritis were retrospectively analyzed. All the patients underwent DHI evaluation and vHIT examination. They were divided into mild handicap group, moderate handicap group and severe handicap group according to DHI score. The correlations between the parameters of vHIT and DHI score were compared among the three groups. The important parameters of vHIT were compared including vestibulo-ocular reflex ï¼VORï¼ gain, gain asymmetry ratio ï¼GAï¼, abnormal saccade dispersion ï¼PR%ï¼.Results:
Of the 46 patients, 10 were in the mild handicap group, 21 in the moderate handicap group, and 15 in the severe handicap group. â In the comparison of the mean value of lateral semicircular canal VOR gain, the vHIT gain of patients with mild, moderate and severe handicap were 0.64±0.06, 0.53±0.11 and 0.37±0.10, respectively, the mean value of VOR gain was negatively correlated with DHI score among the three groupsï¼r=-0.545, P<0.001ï¼, and the pairwise comparisons among the three groups was statistically significantï¼P<0.05ï¼. In comparison of the mean values of lateral semicircular canal GA, the GA values of mild, moderate and severe handicap groups were 46.40±21.81, 47.59±15.17 and 56.57±17.39, respectively, there was no significant linear correlation between GA values and DHI scores among the three groupsï¼r=0.246, P>0.05ï¼, there was no significant difference between the three groupsï¼P>0.05ï¼. In comparison of the mean PR% of the lateral semicircular canal, the mean PR% of patients with mild, moderate and severe handicap group were 32.00±10.62, 53.82±17.09 and 76.00±10.01, respectively, PR% was positively correlated with DHI scoreï¼r=0.726, P<0.001ï¼, and the comparison among the three groups was statistically significantï¼P<0.05ï¼. â¡The vertical semicircular canal vHIT gain of patients with mild, moderate and severe handicap was 0.63±0.06, 0.52±0.15 and 0.38±0.16, respectively, the mean of VOR gain was negatively correlated with DHI score among the three groupsï¼r=-0.487, P<0.01ï¼, the comparison of mild-severe and moderate-severe group was statistically significantï¼P<0.05ï¼, while there was no significant difference between the mild and moderate groupï¼P>0.05ï¼. In the comparison of the mean values of vertical semicircular canal GA, the GA values of mild, moderate and severe handicap groups were 40.40±15.31, 46.10±19.59 and 47.87±18.05, respectively, there was no significant linear correlation between GA values and DHI scores among the three groupsï¼r=0.047, P>0.05ï¼, there was no significant difference in GA among the three groupsï¼P>0.05ï¼. The PR% of patients with mild, moderate and severe handicap were 42.40±15.39, 54.14±17.60 and 64.93±10.95, respectively, there was a positive significant correlation between PR% and DHI scoreï¼r=0.454, P<0.05ï¼, there was statistically significant in the comparison of mild-severe groupï¼P<0.05ï¼, while there was no statistical significance between the other groupsï¼P>0.05ï¼.Conclusion:
The VOR gain and PR% value of vHIT in patients with vestibular neuritis are closely related to the DHI score, which can evaluate the vestibular function and the degree of vertigo.Key words
