Nonlinear Deterministic Models of Postural Control

这个研究项目的总体目的是了解保持直立姿势的过程。这项研究包括分析在安静姿态下记录的压力中心轨迹。目标是确定可重复提取的参数，以表征个体使用的开环和闭环姿势控制机制。此外，还将研究视觉输入和压力中心位置反馈对控制机制的影响。这项研究很重要，因为它可能导致临床可行方法的发展，通过简单的非侵入性测试，客观定量地评估由损伤、疾病和/或衰老过程引起的姿势稳定性变化程度。＊＊＊

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. ***
