Video Head Impulse Test and Seasickness Susceptibility

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.

Treatment and study plan

Video-head impulse testing

Diagnostic Test

Video-head impulse testing is a recent diagnostic bed-side test for evaluation of semi-circular canal function.

Primary outcomes

  1. vHIT gain

    Time frame: Immediate

    measurement of semicircular canal function

  2. paired semi-circular canal asymmetry

    Time frame: Immediate

    (|1st canal gain-2nd canal gain|)/(1st canal gain+2nd canal gain)

Secondary outcomes

  1. anterior semicircular canal gain o ipsilateral horizontal canal gain

    Time frame: Immediate

    anterior semicircular canal gain o ipsilateral horizontal canal gain
