摘　　要：目的研究运动病对姿态平衡的影响。方法对１７名被试者在秋千刺激诱发运动病前、后进行动态姿态平衡测试，研究运动病敏感性与姿态平衡变化的关系。根据耐受时间和运动病症状严重程度，将被试者分为运动病敏感组（１２人）和不敏感组（５人）。结果秋千刺激后１７名被试者综合平衡分显著降低。秋千刺激后运动病敏感组综合平衡分及平衡分（ＳＯＴ４、ＳＯＴ５和ＳＯＴ６）、运动策略（ＳＴＲＡＴ４和ＳＴＲＡＴ６）、感觉分（ＳＥＮ３和ＳＥＮ５）有显著降低，运动病不敏感组没有显著变化；运动病不敏感组刺激前的平衡分（ＳＯＴ２）、感觉分（ＳＥＮ１）和刺激后的运动策略（ＳＴＲＡＴ３）显著高于敏感组。结论运动病对姿态平衡有影响，姿态平衡和运动策略的不稳定性与运动病敏感性有关。Objective To study the effects of motion sickness on posture equilibrium. Method Dynamic posture was tested pre and following motion sickness evoked by parallel swing.17 healthy men were divided into motion sickness sensitive group (12) and motion sickness insensitive groups (5) according to their edurance times and the severeness of symptom. Result The composite equilibrium score significantly decreased post swing in all subjects. The composite equilibrium score, certain other equilibrium scores (SOT4,SOT5 and SOT6), the strategy scores (STRAT4 and STRAT6) and the sensory score (SEN3 and SEN5) significantly decreased in the sensitive group, but unchanged in the insensitive group post swing.The equilibrium score(SOT2),and the sensory score (SEN1) pre swing, the strategy score (STRAT3) of insensitive group is significantly higher than the sensitive group. Conclusion Motion sickness can influence postural equilibrium. Postural instability and instability of strategy are related to the sensitiveness to motion sickness.
