Posturography studies in patients with central and mixed vertigo Summary

Introduction: The aim of the study was to compare the results of posturography in patients with central and mixed vertigo. Material and methods: 50 patients (40 female and 10 male) aged between 26-47 complaining of vertigo were examined during their hospitalization in the Department of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics, Medical University of Lodz in 2014. The subjects were divided into two groups: I – 26 patients (23 female and 3 male) with central vertigo, II – 24 patients (17 female and 7 male) with mixed vertigo. The control group (III) consisted of 26 subjects, students and graduates of Lodz Universities, aged from 19 to 30, that did not complain of vertigo. The subjects were qualified to particular groups based on videonystagmography results. The examinations were conducted with “BioSway portable balance system” by Biodex. Results: In tests on a stable surface, with both closed and opened eyes, subjects with mixed vertigo coped slightly better. In tests on a sponge surface, subjects with central vertigo coped better. Conclusions: Based on the conducted research, it may be concluded that the ability to keep balance in subjects with central and mixed vertigo is on average three times lower than in population not suffering from vertigo episodes.
