摘要： 目的量化评估老年人静态平衡功能，及其随年龄变化的特点及规律。方法60～94岁老年人142例，根据年龄分为7组：60～65岁组、66～70岁组、71～75岁组、76～80岁组、81～85岁组、86～90岁组和90岁以上组，选择18～30岁为健康对照组。采用Tetrax平衡测试系统测定受试者在睁眼自然站立（NO）、闭眼自然站立（NC）、睁眼脚垫站立（PO）、闭眼脚垫站立（PC）4种不同测试状态下的一般稳定性指数（ST）和姿势摆动频谱。结果与对照组比较，老年组ST升高，F1、F4、F6、F8区段摆动强度增加。NO状态：ST、F1、F4、F6、F8在81岁以上各组间有显著性差异（P<0.01）；NC状态：ST、F1、F4在81岁以上各组间有显著性差异， F6、F8在66岁以上各组间有显著性差异（P<0.05）；PO状态：ST、F4、F6在66岁以上各组间有显著性差异（P<0.05），F1、F8在71岁以上各组间有显著性差异（P<0.05）；PC状态：ST、F4在所有老年组间均有显著性差异（P<0.05），F6在66岁以上各组间有显著性差异（P<0.05），F8在76岁以上各组间有显著性差异（P<0.05），而F1在80岁以上老年组有显著性差异（P<0.01）。稳定性指数：NOP<0.01）。姿势摆动强度在F1、F4、F6、F8区段也表现出一致的变化特征。结论80岁以上老年人静态平衡功能显著下降，60～80岁老年人静态平衡功能未见显著下降，但其代偿能力减弱。

Abstract: ObjectiveTo determine the static equilibrium of elderly individuals over the age of 60 and the correlation to the age. Methods142 elderly subjects (60～95 years old) were divided into 7 groups: 60～65 years old group, 66～70 years old group, 71～75 years old group, 76～80 years old group, 81～85 years old group, 86～90 years group, and >90 years old group, 24 cases 18～30 years old as the control. The static equilibrium was examined by measuring the stability index （ST） and the spectrum analysis of postural sway under following 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） using Tetrax Balance System. ResultsThe ST and the intensity of postural sway increased in the elderly group compared with the control group. NO: there were significant differences (P<0.01) in ST, F1, F4, F6, F8 among the 81～85 years group, 86～90 years old group, >90 years old group and the control group. NC: there were significant differences (P<0.01) in ST, F1, F4 among all the elderly groups and the control group, and in F6, F8 among the >66 years groups and the control group（P<0.05）. PO: there were significant differences (P<0.01) in ST, F4, F6 among the >66 years old groups and the control group, and in F1, F8 among the >71 years old groups and the control group（P<0.05）. PC: there were significant differences (P<0.01) in ST, F4 among all the elderly groups and the control group, in F6 among the >66 years groups and the control group, in F8 among the >76 years old groups and the control group, and in F1 among the >80 years old groups and the control group（P<0.05）. The ST distributed as NOP<0.01）. There were similar changes in the intensity of postural sway of F1, F4, F6, F8 bands. ConclusionThere is the significant decline of the static equilibrium in the subjects aged 80 or over and no significant decline of the static equilibrium in the subjects aged 60～80 whose compensation in the static balance may decrease.
