Status: Completed

Conditions: Seasickness

Details and patient eligibility

About

Participants were selected from the military navy crewmembers prior to commencing of active sailing.

A vestibular time constant was calculated based on velocity step testing on a rotatory chair at baseline, 3 months and 6 month following active sailing duty.

A seasickness questionnaire (WIKER) was completed during follow-up visits. study participants were divided to three groups based on WIKER score - susceptible , non-susceptible and habituating. Vestibular time constant was compared between study groups.

Enrollment: 67 patients
