The relationship between vestibular function and gait parameters in vestibular dysfunctional patients with idiopathic sudden sensorineural hearing loss

Abstract

Objective:Based on the application of vHIT, cVEMP test and oVEMP test to locate the peripheral vestibular lesions, we aimed to explore the relationship between vestibular function（semicircular canal and otolith function） and gait parameters in vestibular dysfunctional patients with idiopathic sudden sensorineural hearing loss（ISSNHL）. Methods:In this study, 23 ISSNHL patients（including 14 patients with vertigo） were enrolled. All patients underwent audiometry, Walk Across, vHIT, cVEMP test and oVEMP test. Results:Vestibular otolith function was significantly associated with gait parameters. Semicircular canal function was not associated with any gait parameter. Conclusion:Reduced otolith function was associated with slower and wider steps in patients with ISSNHL. These results indicate that vestibular signals may contribute to specific aspects of gait.
