【摘要】 目的探讨倒视诱发运动病的特点。方法１０名健康青年男性在间隔为５～７ｄ的不同日期分别进行戴两种倒视镜步行试验和平行秋千摆动试验。观察倒视引起的姿态失平衡、倒视和平行秋千诱发运动病症状；计算被试者倒视刺激耐力指数（ＲＶＴＩ）和秋千刺激耐力指数（ＬＡＴＩ），分别表示倒视和秋千诱发运动病易感性。结果步行倒视试验可引起明显的姿态失平衡和运动病症状，失平衡程度与运动病易感性有相关性（Ｐ＜０．０５）。与秋千诱发运动病症状比较，倒视诱发运动病症状较轻，出现较缓慢；上下与左右倒视诱发运动病易感性之间有明显相关（Ｐ＜０．０１）；但倒视诱发运动病易感性与秋千运动病易感性不完全相关。结论倒视试验可引起明显的姿态失平衡和运动病症状，方法简单易行，可应用于地面模拟航天运动病实验和感觉矛盾适应性训练。更多还原

【Abstract】 Objective To make clear the characteristics of motion sickness induced by reversed vision and to see whether it can be used in motion sickness experiments.Methods 10 healthy young men experienced walking tests wearing up-down or left right reversing prisms, and parallel swing test on different days with intervals of 5～7d. Ataxia and motion sickness symptoms induced by walking wearing reversing prisms and those by parallel swing were observed.The reversed vision tolerance index (RVTI) and linear acceleration tolerance index (LATI) were calculated by an empirical formula.Results Both types of reversing prisms can induce obvious ataxia and motion sickness symptoms.The ataxia is correlative (P<0.05) with the susceptibility to motion sicness. In comparison with symptoms of swing motion sickness, the symptoms of reversed vision motion sickness are not too serious and appear slowly. There are correlativities (P<0.01) between the susceptibility to motion sickness induced by up down and left right reversing prisms. The susceptibilities to motion sickness induced by reversing prisms are not correlative completely with that by swing.Conclusion Reversed vision test is simple and easy and can be used for simulating space motion sickness or training of adaptation to sensory conflict on the ground.更多还原
