Neuromuscular and Biomechanical Factors Underlying Human Posture Control

即使在健康的年轻人中，保持直立姿势的任务也涉及一个复杂的控制系统。这个项目旨在增加对影响姿势控制的神经系统、肌肉和生物力学因素的理解。该项目使用一种新开发的定量方法来研究姿势控制，称为“稳定程序扩散分析”（SDA），以分析个体站立时细微的姿势调整和动作。实验利用这一分析来检验这种调整与不同的姿势影响之间的关系，比如肌肉活动水平和身体的惯性。研究结果被用来理解不同的感觉和运动控制系统在保持有效的姿势控制中的作用。该项目将显著提高对身体如何有效控制姿势和运动的理解，并将为理解由衰老或平衡障碍导致的姿势控制困难提供重要见解。它的结果对机械系统的发展也很重要，比如假肢或机器人设备，它们需要快速、有效地控制稳定的平台。

9603863 Collins The task of maintaining an upright posture involves a complex control system even in a healthy, young individual. This project is designed to increase the understanding of the nervous system, muscle, and biomechanical factors that influence postural control. The project uses a newly developed quantitative approach to studying postural control called "stabilogram-diffusion analysis" (SDA) to analyze the subtle postural adjustments and movements individuals make as they stand. Experiments use this analysis to examine such adjustments in relation to different influences on posture such as muscle activity levels and the body's inertia. The results are then used to understand the role of different sensory and motor control systems in maintaining effective postural control. This project will significantly improve the understanding of how the body effectively controls posture and movement, and in so doing will provide insights important for understanding the postural control difficulties that result from aging or balance disorders. Its results will also be important for the development of mechanical systems such as prosthetic limbs or robotic devices that require fast, effective control of stable platforms.
