1126182SmithThe motion, metabolic, and force analysis system requested would benefit research, research training, and education in the Biomechanics Lab and Rocky Mountain Cancer Rehabilitation Institute (RMCRI) at the University of Northern Colorado (UNC). 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.

1126182Smith 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 (UNC) 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。了解与假肢结构特征相关的机制、截肢者运动的较高能量成本以及下肢截肢者常见的行走不对称可能会影响假肢设计和康复计划。涉及下肢截肢者的两个新研究项目将受益于购买所需设备。其中一个项目将研究增加假肢质量对截肢者运动的力学和能量学的影响。第二个重点是通过创建一种识别假肢脚踝即时旋转中心的方法来改进假肢脚踝的模型。目前生物力学实验室的研究仅限于 2D 分析，但随着所需设备的获得，拟议的研究将扩展到 3D 分析。
