摘要：

背景：由于人体运动过程复杂，难以用直接的方法来测量膝关节各项力学参数，所以，通常使用模拟或根据逆向动力学推算的方式来求得所需参数值。
目的：总结和比较膝关节力矩参数的测定方法，找出一种合理、可靠性高、实用性广的方法。
方法：应用计算机检索CNKI，万方数据库，Elsevier公司的Science Direct电子期刊关于膝关节力矩参数测试方法的文献，以“膝关节，力矩，等速测力法，拉格朗日建模，神经网络建模”及“knee joint，torque，isokinetic dynamometer，lagrangian modeling，neural network modeling”为检索词进行检索。纳入文章内容与人体膝关节力矩参数相关，同一领域文献则选择近期发表或发表在权威杂志文章。
结果与结论：检索文献量总计123篇，排除重复性研究，初检得到75篇文献，阅读标题和摘要进行初筛，共保留其中的35篇归纳总结。结果表明，等速测力虽是主流方法，但是存在可靠性不够高的问题，且相应的等速测力仪价格昂贵，而朗格朗日建模与神经网络建模可以通过改变各自的模型来达到期望的要求，故有更大的可靠性与实用性，后者有更大的发展前景。

Abstract:

BACKGROUND: Parameters of knee joint are not directly measured due to complex body motion. Therefore, the parameters are obtained by simulation or reverse dynamics.
OBJECTIVE: To conclude and compare the method of determining torque parameters, and to find a reasonable, responsible, practical method. 
METHODS: A computer-based online search of CNKI, Wanfang, and Science Direct databases, articles related to measurements of torque parameters were searched with key words “knee joint, torque, isokinetic dynamometer, lagrangian modeling, neural network modeling” in Chinese and English. Correlated and newly-published articles were included.
RESULTS AND CONCLUSION: A total of 123 articles were collected, and 75 were firstly selected following exclusion of repetitive articles. Finally, 35 articles were included according to title and abstract. Results show that isokinetic dynamometer has been extensively used, but reliability is low, and the price of dynamometer is expensive. Lagrangian modeling and neural network modeling can be modified to obtain reliability and practicality.
