Research Abstract |
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.
