Dynamic Stabilization of Stance via Foot Placement

本研究的目的在于分析踏步时的姿势稳定性。这项研究将结合实验和理论方法。对正常人的实验将使用表面电极测量地面反作用力和肌肉的电活动。机械系统用一个具有8个自由度的三维数学模型来描述；该模型将用于解释实验结果。这项研究将增加对步进过程的理解，并可能导致功能性电刺激系统的改进设计。这种系统在研究中越来越多地用于恢复截瘫患者的运动能力。

The purpose of this study is to analyze the stabilization of posture during stepping. The research will combine experimental and theoretical approaches. Experiments on normal subjects will measure ground reaction forces and the electrical activity of muscles using surface electrodes. The mechanical system is described by a 3-dimensional mathematical model that has 8 degrees of freedom; this model will be used for the interpretation of the experimental results. The research will increase understanding of the stepping process, and may lead to the improved design for functional electrical stimulation systems. Such systems are being increasingly utilized in research to restore motility in paraplegic individuals.
