Video Head Impulse Test and Seasickness Susceptibility

Not Applicable

Completed

• Conditions: Sea Sickness
• Interventions: Diagnostic Test: Video-head impulse testing

• Registration Number: NCT05657340
• Lead Sponsor: Medical Corps, Israel Defense Force

Brief 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.
