Video Head Impulse Test and Seasickness Susceptibility

NCT05657340 | Completed

• 1 other identifier: IDF-1873-2018
• Study Type: interventional

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.

Conditions

Sea Sickness

Keywords

motion sickness; video head impulse test; vestibular testing; seasickness susceptibility

Outcome Measures

Primary Outcomes (2)

• vHIT gain

  measurement of semicircular canal function

  Immediate

• paired semi-circular canal asymmetry

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

  Immediate

Secondary Outcomes (1)

• anterior semicircular canal gain o ipsilateral horizontal canal gain

  Immediate

Study Arms (2)
