The aim of the study was to determine balance parameters in a group of young patients with vertigo symptoms and to verify posturography helpfulness in clinical evaluation of vestibular system pathology. Methods: 77 children and adolescents of age 3–18 suffering from vertigo episodes participated in the study (46 girls, 31 boys). They underwent audiology objective tests and balance test on stable surface. Calculated balance parameters were analyzed in reference to: eyes opened and closed, age influence, sway comparison in anterior-posterior and medial-lateral, differences between subgroups with and without vestibular deficits. Discriminant analysis was performed to assess classification ability to impaired group in two cases: only balance parameters and both audiology and balance parameters. Results: Patients with vertigo symptoms generally keep their balance properly on stable surface. Balance parameters do not depend on presence of vestibular system pathology. Values increased in eyes closed conditions. Left/Right and Anterior/Posterior differences were not statistically significant. The negative correlation between age and some balance parameters is present, stronger in the case of eyes opened and weaker or absent in vestibular impaired group. Also, correlations between axes were found, higher in impaired group in comparison with not impaired one. Conclusions: Discrimination based on balance parameters is poor not comparable to one built on combined: audiology and balance parameters, so typical balance parameters’ analysis is not so useful in clinical practice when the reason of vertigo episodes should be assessed, but verify compensation process and measure with objective numbers the progress of recovering, the actual functional patient’s status.
