DESCRIPTION (provided by applicant): This is a proposal for five years of support, to complete Biomedical Engineering PhD training at the University of Michigan (UM) in the biomechanics of trunk control in older adults, a major issue in avoiding falls. The career development plan includes coursework to develop competencies in biomechanical modeling and neuromuscular control participation in joint seminars at the mentor's laboratories, participation in seminars related to aging at the UM Institute of Gerontology, presentation at national meetings, and submission of manuscripts for publication. A research project has been identified that will eventually lead to a more specific thesis. Three aims are proposed for the research plan: 1) Identify biomechanical factors governing trunk control in healthy and fall-risk older adults, including trunk strength, velocity, and proprioception under static and dynamic conditions; 2) Assess the relationship between these factors and clinical tests of fall risk; and 3) Model trunk control system dynamics, particularly under conditions of muscle function or sensory deficits. Primary mentor will be Nell Alexander MD, Director of the Mobility Research Center, who has extensive experience in aging mobility studies, particularly in postural control. Co-mentor will be James Ashton-Miller PhD, biomechanical engineer and Director of the Biomechanics Research Laboratory.

描述（由申请人提供）：这是一项支持五年支持的建议，以在密歇根大学（UM）的老年人中躯干控制生物力学上完成生物医学工程博士培训，这是避免跌倒的主要问题。职业发展计划包括开发生物力学建模和神经肌肉控制的能力的课程。已经确定了一个研究项目，最终将导致更具体的论文。为研究计划提出了三个目的：1）确定在健康和秋季风险老年人中控制躯干控制的生物力学因素，包括静态和动态条件下的树干强度，速度和本体感受； 2）评估这些因素与跌倒风险的临床测试之间的关系； 3）模型躯干控制系统动力学，特别是在肌肉功能或感觉缺陷的条件下。主要导师将是移动研究中心主任内尔·亚历山大（Nell Alexander）医学博士，他在移动性研究中具有丰富的经验，尤其是在姿势控制方面。 Co-Encormor将是生物力学工程师兼生物力学研究实验室主任James Ashton-Miller博士。
