多节段肢体的运动需要产生适当的关节力矩，其中包括运动节段之间的动态相互作用以及重力等外力所产生的术语。对于单个关节运动，不存在惯性力、向心力和科里奥利力产生的相互作用力。在不同的运动路径和运动速度下，评估了在只涉及肩关节和肘关节的水平面上伸展运动时个体相互作用力的重要性。提出了简化动力学计算的轨迹形成策略。
Movement of multiple segment limbs requires generation of appropriate joint torques which include terms arising from dynamic interactions among the moving segments as well as from such external forces as gravity. The interaction torques, arising from inertial, centripetal, and Coriolis forces, are not present for single joint movements. The significance of the individual interaction forces during reaching movements in a horizontal plane involving only the shoulder and elbow joints was assessed for different movement paths and movement speeds. Trajectory formation strategies which simplify the dynamics computation are presented.
