关节力学的动力学是电机系统的基本特性。它们决定了姿势控制过程中由扰动力引起的位移，以及执行随意运动所必须产生的力。本文综述了这些动力学的实验研究，重点是在警觉的人类单关节的行为。首先总结了已使用的实验和分析方法的技术方面。主要结果与不同的方法，然后进行审查，比较和对比。这些结果的解释，然后考虑的基本生理机制，强调组织的被动特性，肌肉的机械行为，和牵张反射的相对贡献。最后，重要的悬而未决的问题，关于联合力学的动力学进行审查。
The dynamics of joint mechanics are a fundamental characteristic of the motor system. They determine the displacements evoked by perturbing forces during postural control and the forces that must be generated to perform a voluntary movement. This article reviews experimental studies of these dynamics, with an emphasis on the behavior of single joints in alert humans. Technical aspects of the experimental and analytic methods that have been used are summarized first. Major results obtained with the different methods are then reviewed, compared, and contrasted. The interpretation of these results in terms of the underlying physiological mechanisms is then considered, with an emphasis on the relative contributions of passive properties of tissue, the mechanical behavior of muscle, and stretch reflexes. Finally, important unanswered questions regarding the dynamics of joint mechanics are reviewed.
