title: [Study on space motion sickness before, during and after spaceflight].
abstract: Space motion sickness has long been a difficult medical problem in human space flight. Because it is a group of syndromes of the astronauts in adaptation to the new space environment and is related to a wide range of factors, the research of space motion sickness is different from that of cardiovascular and pulmonary system. Subjective methods and qualitative investigation are frequently used, and quantitative analysis is limited since objective stimuli that can be used in specific space environment are few and the samples are small. So precise localization of the problem is very difficult. In this paper space vestibular experiments and works on perceptions of space motion sickness completed by Russian and American scientists are reviewed, in the hope that it may provide some references for future space medical researches.
