MRI: Acquisition of a motion, metabolic, and force analysis system for research and research training related to biomechanical deficits

所要求的运动、代谢和力分析系统将有利于北科罗拉多大学生物力学实验室和落基山癌症康复研究所（RMCRI）的研究、研究培训和教育。了解假肢的结构特征、截肢者运动时较高的能量消耗以及下肢截肢者常见的行走不对称的相关机制可以影响假肢的设计和康复计划。两个涉及下肢截肢者的新研究项目将受益于获得所要求的设备。其中一个项目将研究增加义肢质量对截肢者运动力学和能量学的影响。第二部分将重点改进假肢脚踝的模型，创建一种识别假肢脚踝瞬间旋转中心的方法。生物力学实验室目前的研究仅限于二维分析，但随着所需设备的获得，拟议的研究将扩展到三维分析。

Understanding mechanisms associated with the structural characteristics of the prosthesis, the higher energetic costs of amputee locomotion, and common walking asymmetries in lower extremity amputees could impact prosthetic design and rehabilitation programs. Two new research projects involving lower extremity amputees would benefit from the acquisition of the requested equipment. One project would investigate the effect of increasing prosthesis mass on the mechanics and energetics of amputee locomotion. The second would focus on improving models of the prosthetic ankle by creating a method for identifying the instant center of rotation of prosthetic ankles. Current research in the Biomechanics Lab has been limited to 2-D analyses, but with acquisition of the requested equipment, the proposed research would expand to 3-D analyses.
