Case Report: Vestibular Rehabilitation in Isolated Otolith Dysfunction After Covid-19: A Case Report

Abstract

Introduction: A 56-year-old female with dizziness, imbalance, and a slight floating sensation was evaluated. Her symptoms started after infection with the novel coronavirus (SARS-CoV-2).Case Presentation: Routine auditory test (pure tone audiometry), vestibular assessment(videonystagmography), and neurologic test results were in the normal range, but the otolithevaluations, such as cervical Vestibular Evoked Myogenic Potentials (cVEMP) and subjectivevisual vertical tests, showed abnormal findings. The patient underwent a ten-session individualizedvestibular rehabilitation program (one session per week).Results: After completing rehabilitation sessions, her chief complaints were alleviated, theperformance on computerized posturography was improved, and the abnormal cVEMP amplitudeasymmetry between ears disappeared.Conclusion: In conclusion, vestibular disorders can happen after COVID-19 infection, presentingexclusively with isolated otolith dysfunction. In these patients, functional integrity assessment ofthe whole vestibular system is crucial, and vestibular rehabilitation may be beneficial
