Clinical Trial Summary

This a case control study on seasickness susceptibility. 86 healthy maritime personal were divided to seasickness susceptible and non susceptible groups based on a seasickness questionnaire (Golding) and motion sickness score. All subjects from both groups underwent video head impulse testing (vHIT). VHIT parameters - gain, asymmetry ect were compared between both groups.
