Evaluation of video head impulse test findings in cases with motion sickness

In order to clarify the role of the canal otolit conflict in motion sickness (MS), the labyrinth functions of 20 patients with anamnesis of MS, and 20 healthy volunteers were evaluated by video head impulse test (VHIT). The gain values of LAT.right, LAT.left, LAT asymetry, RA, LP, RALP asymetry, LA, RP and LARP asymetry were recorded. In addition, the symptoms of the patients in study group were recoded in the MS patient evaluaton form, and the severity of the symptoms were also recorded. There was no statistically significant difference for VHIT gain values of the patients between control and study groups. In addition, there was no correlation between symptom scores and VHIT gain values. Theory of canal otolit conflict in MS pathophysiology could not be supported with findings of the present study.
