摘要: 目的应用最大重心-压力中心倾角法比较青、中、老年人群静态平衡能力差异及特征。方法使用三维运动捕捉系统及测力台,采集15 名青年人(18~40 岁)、10 名中年人(41~65 岁)及12 名老年人(>65 岁)在睁眼双足站立、闭眼双足站立、睁眼单足站立及闭眼单足站立4 种状态下的重心及压力中心数据,计算其在矢、冠状面上的重心-压力中心倾角,以各组平均峰值进行统计分析。结果在睁眼双足站立及闭眼单、双足站立3 种状态下,不同年龄段人群在矢、冠状面的倾角均无显著性差异(P>0.05);而在睁眼单足站立时,青、中年组与老年组间,在矢、冠状面的倾角均有显著性差异(P<0.05)。结论睁眼单足站立下的最大重心-压力中心倾角可以敏感地检测出老年人群的平衡功能衰退,有望为临床静态平衡提供一种新的静态平衡评估指标。

Abstract: Objective To compare the difference of static balance ability in different aged people, with the maximum angle of center of mass (COM) and center of pressure (COP). Methods 37 healthy people without cardiovascular and cerebrovascular diseases including 15 young people (18~40 years old), 10 middle age people (41~65 years old) and 12 old people (>65 years old) participated in this study. The maximum angle of COM-COP and the corresponding envelope areas were recorded in 4 standing posture: natural standing, close eyes standing, single leg standing and single leg standing with eyes closed. Results There was no significant difference in the maximum angle of COM-COP among 3 groups in 3 states (nature standing, close eyes standing, single leg standing with eyes closed) (P>0.05), but there was significant difference in the state of single leg standing (P<0.05) between the young and the old, and the middle-aged and the old. Conclusion The maximum angle of COM-COP in the state of single leg standing can sensitively detect the deterioration of stability of older people. It may be a new index of static balance in clinic.
