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.
