Study 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.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. vHIT gain

    measurement of semicircular canal function

    Time frame: Immediate

  2. paired semi-circular canal asymmetry

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

    Time frame: Immediate

Secondary outcomes

  1. anterior semicircular canal gain o ipsilateral horizontal canal gain

    anterior semicircular canal gain o ipsilateral horizontal canal gain

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2019 to primary completion in May 2020, 16 months.

Of 15 interventional studies with no phase under Motion Sickness, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 29. This study's 16 months is close to that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 20, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
