Nonlinear Deterministic Models of Postural Control

9308659柯林斯本研究项目的总体目的是了解保持直立姿势的过程。本研究涉及的轨迹的压力中心记录在安静的立场的分析。目标是确定可以重复提取的参数，其特征在于个人使用的开环和闭环姿势控制机制。此外，视觉输入和压力中心位置反馈的控制机制的影响将进行调查。这项研究是重要的，因为它可能会导致一个临床上可行的方法，客观和定量评估的程度造成的损伤，疾病和/或老化过程中，通过一个简单的，非侵入性的测试姿势稳定性变化的发展。***

9308659 Collins The general aim of this research project is to understand the process of maintaining erect posture. The study involves the analysis of the trajectory of the center-of-pressure recorded during quiet stance. The goal is to determine parameters that can be extracted repetitively that characterized the open-loop and closed-loop postural control mechanisms being used by an individual. Also, the effects of visual input and center-of- pressure position feedback on the control mechanisms will be investigated. This study is important since it could lead to the development of a clinically viable methodology for objectively and quantitatively assessing the degree of postural stability changes resulting from injury, disease and/or the aging process through a simple, non-invasive test. ***
