The aim: This given work is dedicated to examine the correlation of results of the ambulant screening vHIT test conducted by applying ICS Impulse device, with results of standard appliance otoneurological videonystagmography (VNG) testing. Comparison of given results will provide assessment of vHIT test effectiveness for otoneurological diagnosis of patients suffering giddiness or any other equilibrium system disorder.
Reference and method: Diagnosis was reached with 20 patients suffering vestibular disorders with no specific ailment location. From overall VNG test there was a caloric testing extracted, containing assessment of canal paresis and directional preponderance. Numerical values of these parameters were compared to vHIT test result - the indicator of "gain" eye-ball movement imaging head move, to be specific.
Results: Conducted examinations did not reveal any significant correlation between VNG and vHIT parameters however it is need to be emphasized here, that most of the considered cases were not affected but any defect of vestibular canal receptor. Nevertheless, unsettled values of "gain" indicator may signify that vHIT regardless of ailments location is defected.
Conclusion: vHIT test with its quantitative analysis may in the future become indicator of auricular disorders.
