Abstract
Objective: To investigate the effects of SARS-CoV-2 infection on body balance and sleep quality of subjects with post-COVID-19 syndrome, after 12 months of infection. Methods: Cross-sectional, quantitative, observational study with 36 subjects. All underwent anamnesis, inspection of the acoustic meatus, Pittsburgh Sleep Quality Index, Dynamic Foam Laser Posturography, and Vestibular Evoked Myogenic Potential. Results: In posturography, the values were below normal in the evaluations of the somatosensory and vestibular systems. There was no statistical difference in the Vestibular Evoked Myogenic Potential. In the comparison between self-report and Sleep Quality Index, a difference in sleep quality was observed. Conclusion: Subjects with Post-COVID-19 Syndrome 12 months after infection showed altered sensory integration of the proprioceptive system and visual preference, with no functional impairment of the neural pathways of the vestibulocervical and vestibuloocular reflexes. Nevertheless, sleep quality is unrelated to maintaining body balance, although self-reported sleep disturbances appear to be a likely sequelae of Post-COVID-19 Syndrome.
