Low-Dimensional Dynamic Modeling of Human Gait

人体步态的低维动力学建模Westerpyruvone，The俄亥俄州州立大学，哥伦布市，俄亥俄州。该项目提出通过开发真正的低维人类步态模型来提高对人类步态的科学理解。机器人学中流行的仿生学方法生物系统被用来激发机器设计将被转化为生物力学中的仿生学方法，其中来自机器人学的想法将被用来激发对生物系统即人类的研究。具体寻求的是低维模型，可以作为模板的动态系统代表人类步态。这些模型将通过“修剪掉”人类步态的关节和肌肉的所有附带复杂性而发现，同时只保留动态的突出方面。开发的模型将使新的步态分析工具得以开发。 具体而言，模型可用于创建一种新的方法来设计和下肢假体的对齐。这将改善美国每年125 000名下肢截肢者中的一大部分人以及现有截肢者的生活质量。这项工作将支持一名在下肢假肢装置设计方面具有丰富工业经验的女研究生。她回到研究生院是因为她渴望追求学术生涯，所以这笔赠款将直接帮助未来的女性工程教师的发展。

AbstractLow-Dimensional Dynamic Modeling of Human GaitEric R. Westervelt, The Ohio State University, Columbus, Ohio.This project proposes to improve the scientific understanding of human gait through the development of true low-dimensional models of human gait. The popular biomimetic approach to robotics-where biological systems are used to inspire machine design-will be inverted to be a robo-mimetic approach to biomechanics, where the ideas from robotics will be used to inspire the study of a biological system, the human. Specifically sought are low dimensional models that can serve as the template dynamical systems representative of human gait. These models will be found by 'trimming away' all the incidental complexity of joints and muscles of the human's gait while retaining only the salient aspects of the dynamics.The developed models will enable novel gait analysis tools to be developed. Specifically, the models may be used to create a novel approach to the design and alignment of lower-limb prostheses. This will result in improved quality of life for a large fraction of the 125,000 persons per year who undergo a lower-limb amputation in the United States, as well as existing amputees. This work will support one female graduate student who has extensive industrial experience in the design of lower-limb prosthetic devices. Her return to graduate school was prompted by her desire to pursue an academic career, so this grant will directly aid in the development of a future female engineering faculty member.
