Abstract

Abstract: Objective: Posturography (PG) shows various patterns corresponding to a patient's equilibrium condition; however, PG is not useful for the differential diagnosis of peripheral vestibular diseases (PVDs). The aim of this study was to identify parameters of PG that can distinguish between PVDs. Methods: The differences in PG parameters between PVDs were evaluated retrospectively. Two hundred and two patients with Ménière's disease (MD), 154 patients with benign paroxysmal positional vertigo (BPPV), 20 patients with sudden sensorineural hearing loss with vertigo (SSNHLwV), and 31 patients with vestibular neuritis (VN) underwent PG during the non-acute phase of vertigo, from January 2010 to March 2017. Results: The velocity of body oscillation of BPPV patients with eyes open and closed were significantly faster than those of MD patients with eyes open ( p < 0.001) and closed ( p = 0.033). The velocity of body oscillation of VN patients with eyes open was significantly faster than that of MD patients with eyes open ( p = 0.0083). There were no significant differences among the other PG parameters between PVDs. Although there were significant differences among the velocity with eyes open and closed between males and females (eye open: p = 0.0009, eye close: p < 0.0001), there was no significant difference in the ratio of males to females among PVDs ( p = 0.1834). Therefore, the ratio did not influence the difference in velocity among PVDs. Patient age correlated with the velocity with eyes open ( p < 0.001) and with eyes closed ( p < 0.001). Post-hoc analysis revealed significant differences in patient age, and comparisons of MD and BPPV, MD and SSNHLwV, BPPV and VN, and VN and SSNHLwV. Therefore, we performed multiple regression analysis to determine whether the significant differences in the velocity of body oscillation among PVDs were caused by the difference in age distribution between PVD groups, rather than by differences in the PVDs themselves. There were correlations between age and the velocity of body oscillation with eyes open ( p < 0.001) and with eyes closed ( p < 0.001). There also were correlations between MD or VN and the velocity of body oscillation with eyes open ( p = 0.0194). Conclusion: There were significant differences in the velocity of body oscillation with eyes open between MD and VN patients. The difference between MD and VN was significant regardless of the age distribution. To distinguish between MD and VN, the velocity of body oscillation with eyes open is a useful PG index.
