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.

9603863 Collins保持直立姿势的任务即使是健康的年轻人，也涉及复杂的控制系统。 该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。该项目使用新开发的定量方法来研究称为“稳定扩散分析”（SDA）的姿势控制，以分析个人在站立时所做的微妙的姿势调整和运动。实验使用此分析来检查有关姿势的不同影响，例如肌肉活动水平和身体的惯性。然后，结果用于了解不同感觉和运动控制系统在维持有效姿势控制中的作用。该项目将显着提高人们对身体如何有效控制姿势和运动的理解，因此，这样做将为理解衰老或平衡疾病造成的姿势控制困难提供重要的见解。 它的结果对于需要快速，有效控制稳定平台的机械系统（例如假肢或机器人设备）的开发也将很重要。
