Exposure to extended periods of weightlessness in orbital flight has profound effects on the neurovestibular system and influences head and eye movements, postural control, and spatial orientation. The associated space motion sickness is among the earliest of the signs of adaptation to this new environment. This report both reviews the prominent neurovestibular phenomena associated with going into space and returning to earth and relates the issues to vestibular compensation and rehabilitation. New results from the Spacelab SLS-2 mission are included, showing significant reductions in postflight ocular counterrolling and changes in ocular counterrolling left/right asymmetries after 2 weeks in space.
在轨道飞行中长时间暴露于失重环境会对神经前庭系统产生深远影响，并影响头部和眼球运动、姿势控制及空间定向。相关的太空晕动病是适应这种新环境最早出现的症状之一。本报告既回顾了与进入太空和返回地球相关的突出神经前庭现象，又将这些问题与前庭代偿及康复联系起来。其中还纳入了太空实验室SLS - 2任务的新结果，显示在太空飞行2周后，飞行后眼反向转动显著减少，且眼反向转动左右不对称性发生了变化。
