目的：研究绝经后妇女膝关节肌力与静态平衡之间的相关性。
方法：60例绝经后妇女，分别用PJ-I型电脑平衡功能检测仪测定静态平衡功能，Cybex-330等速肌力测试仪测试膝关节肌力，将所测定的平衡功能参数与肌力参数做相关性分析，按年龄分为65岁以下（含65岁）以及65岁以上年龄组，每组组内进行肌力与平衡功能相关性分析。
结果：总体上静态平衡功能与下肢肌力之间无直线相关，按年龄分组后，65岁以上年龄组平衡功能与下肢肌力间存在相关性。
结论：年龄相关的平衡功能减退涉及的因素繁杂，单纯膝关节肌力下降一般不至于引起显著的静态平衡功能低下。 |

| Abstract
Objective: To study the correlation between lower-extremity muscle strength and balance in elderly women.
Method: Sixty community-dwelling elderly women aged between 56 and 79 participated in our research. The static standing balance of these subjects was performed using a PJ-I computerized stabilometer with their eyes open and closed. Knee flexors and extensors strength at 60°/s and 120°/s and 180°/s of the left leg was tested with a Cybex-330 isokinetic dynamometer.
Result: In total, lower-extremity muscle strength did not correlate with the static standing balance in elderly women, but when divided into two groups by age, the parameter of balance such as Romberg rates was correlated to peak torque of knee extensors at 60°/s and 120°/s, and L/Earea was correlated to the torque ratio of agonist/antagonist muscles for the knee extension at 180°/s in the older group.
Conclusion: Decreasing in the lower-extremity muscle strength is not necessarily lead to bad performance in balance, only when accompanies with other dysfunctions such as proprioception dose it affects standing balance. |
