Abstract: 目的 通过对外周性眩晕患者进行计算机动态姿势图检查,定量分析前庭功能障碍者姿势控制的能力. 方法 对91例经双耳变温试验证实为外周性眩晕的患者按照试验结果分为单侧前庭功能障碍组(单侧组)和双侧前庭功能障碍组(双侧组).两组均进行计算机动态姿势图检查,包括感觉整合试验(sen-sory organization test,SOT)、运动控制试验(motor control test,MCT),并与正常参考值通过t检验进行比较.结果 单侧组的SOT结果与正常参考值的差异无统计学意义(P>0.05),双侧组SOT平衡综合分低于正常参考值,在平台及视觉刺激变化下更明显(P<0.05).两组MCT的潜伏期与正常参考值的差异无统计学意义(P>0.05).结论 外周性前庭功能障碍者在眩晕发作的非急性期,均能维持静态平衡,单侧前庭功能障碍者能维持动态姿势平衡,但双侧前庭功能障碍者的动态姿势平衡功能较正常人降低.
