The purpose of this study was to investigate dynamic interaction between body segments during human quiet standing. To achieve this end, we quantified the mutual contributions of the ankle and hip joint torques, respectively, to the ankle and hip angular accelerations by using a technique often called "induced acceleration analysis". We found that angular motion of each joint was accelerated equally both by a direct effect from its own torque and by an indirect, remote effect from the adjacent joint torque. Our present result indicates that there is significant inertial coupling between the ankle and hip joint during quiet standing. To ensure stability of the posture under such condition, interference from higher-level neural processing(involving the cerebellum) may be required.

本研究旨在探讨人体安静站立时身体各部分之间的动态互动。为了实现这一目标，我们量化的踝关节和髋关节的扭矩，分别对踝关节和髋关节的角加速度的相互贡献，通过使用一种技术，通常被称为“诱导加速度分析”。我们发现，每个关节的角运动加速相等的直接影响，从自己的扭矩和间接的，远程的影响，从相邻的关节扭矩。我们目前的研究结果表明，在安静的站立过程中，踝关节和髋关节之间存在着明显的惯性耦合。为了确保在这种情况下姿势的稳定性，可能需要来自更高级别的神经处理（涉及小脑）的干扰。
