简要总结
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.

结局指标
主要结局
6 month follow up vestibular time constant measurement.
时间窗: 6 months
vestibular time constant in seconds is the measurement of decline in maximal slow phase velocity of eye movement during nystagmus to 37% of initial value produced by abrupt acceleration and declarations in a rotatory chair - step velocity protocol.
