本研究的目的是：1）调查单个项，如摆动腿关节力矩，运动依赖项（MDT）和其他项的膝关节角速度的产生的贡献，和2）量化的功能作用的关节力矩在摆动腿运动中的MDT的生成因子的考虑。摆动腿在矢状面上被建模为三个刚性段的连接系统。使用摆动腿模型的运动方程计算MDT的动态贡献和生成因子。研究结果表明：1）MDT是膝关节角速度产生的重要因素之一; 2）MDT的主要产生因素是摆动腿关节力矩。
The purposes of this study were 1) to investigate the contribution of individual terms such as the swing leg joint torques, motion-dependent term (MDT) and other terms to the generation of the knee joint angular velocity, and 2) to quantify the functional roles of the joint torques in the swing leg motion with consideration of the generating factor of the MDT. The swing leg was modeled as a linked system of three rigid segments in sagittal plane. Dynamic contributions and generating factors of the MDT were calculated using the equation of motion for the swing leg model. The results obtained in this study indicate that 1) the MDT was one of the great contributors to the generation of the knee joint angular velocity, and 2) the main generating factors of the MDT were the swing leg joint torques.
