The Coronavirus disease 2019 (COVID-19) caused by the Severe Acute Respiratory Syndrome coronavirus was considered a global pandemic and a major public health problem worldwide. While COVID-19 infection primarily affect the respiratory system, there is recent growing evidence of neurological involvement of COVID-19 involving both central and peripheral nervous systems with symptoms including dizziness, headaches, fatigue, and loss of consciousness. The physiology of human peripheral and central vestibular systems is complex and highly integrated. It maintains a person's balance through the simultaneous interaction of various subsystems. VNG is the most commonly practiced method of vestibular assessment due to the close physiological connections between the vestibular and the visual systems , it can record and measure nystagmus that enables simultaneous subjective observation of eye movements together with objective data collection and analysis.
Accordingly, this study was designed to assess the effect of COVID-19 infection on the vestibular system in a sample of COVID-19 patients complaining of dizziness that temporally related to the infection compared to a control group.
