摘要： 目的评价前庭感觉、本体感觉及视觉功能对老年人跌倒风险的影响。方法56例60岁以上老年患者采用Tetrax平衡测试系统分别检测受试者在自然站立（NO）、闭眼自然站立（NC）、脚垫站立（PO）、脚垫闭眼站立（PC）4种不同测试状态下的一般稳定性指数（ST）、体重分布指数（WDI）和跌倒指数（FI）。结果平均FI（48.21±26.47）；ST：PC组＞PO组＞NC组＞NO组（P=0.000），但NC组与PO组无显著性差异（P=0.705）；WDI各组间无显著性差异（P=0.057）。FI与不同姿势ST相关（P<0.05）；与不同姿势WDI的无相关性（P>0.05）。结论视觉、本体感觉和前庭感觉在姿势控制和跌倒预测方面均有重要作用；稳定性指数不仅能精确反映静态平衡功能状态和姿势控制能力，而且能初步反映感觉因素对平衡调控和跌倒风险的影响；体重分布指数评估跌倒风险不敏感。

Abstract: ObjectiveTo assess the effect of the vestibular, visual, and somato-sensation on the fall risk in elderly individuals. Methods56 subjects aged 60 or over were measured with the static postural stability and fall risk, including stability index （ST）, the body weight distribution index (WDI) and the fall index (FI) under 4 conditions: standing on solid surface with eyes open （NO），standing on solid surface with eyes closed （NC）， standing on pillows with eyes open （PO），and standing on pillows with eyes closed （PC）. ResultsThe mean of fall index of all subjects was (48.21±26.47). The ST was different among groups, which was PC>PO>NC>NO （P=0.000），but no significant differences were noted between PO and NC groups （P=0.705）. The WDI was not significantly different among the 4 groups (P>0.05）. The FI was correlated with ST （P<0.05）, but not correlated with the WDI（P>0.05）. ConclusionAll of the vestibular, visual, and somato-sensory systems play an important role in the balance, postural stability and falls. The ST is sensitive to evaluate the static balance function and associated with the fall risk in an elderly population. The WDI is not sensitive enough to evaluate the static balance function and fall risk.
