Neurovestibular Symptoms in Astronauts Immediately after Space Shuttle and International Space Station Missions:

摘要

Objectives(1) To assess vestibular changes and related sensorimotor difficulties, especially instability of posture and gait, among astronauts immediately after they return from space and to compare the effects experienced after short- and long-duration space missions. (2) To determine whether any difficulties experienced were severe enough to impair the astronauts’ ability to leave the spacecraft in the event of an emergency.Study DesignProspective cohort study.SettingNational Aeronautics and Space Administration’s Kennedy Space Center and Johnson Space Center.Subjects and MethodsFourteen crewmembers of 3 Space Shuttle missions that lasted about 1 week and 18 crewmembers of 8 International Space Station missions that lasted about 6 months were given brief vestibular examinations 1 to 5 hours after landing. These examinations focused on the presence of vestibular and motor coordination difficulties, as well as motion sickness and motion sensations. Standardized tests included the observation of abnormal e...
