DESCRIPTION (provided by applicant): This proposal will utilize innovative, technologies to allow below the knee amputees to walk and run using a single powered prosthetic device. Current users of passive prosthetic devices typically expend more energy; have reduced ankle motion and power; and increased gait asymmetry resulting in joint and back pain. Augmenting ankle power with a robotic tendon actuator will restore near able bodied function improving quality of life. A pilot study will be conducted in preparation for a larger biomechanics study in phase two. A new running controller will be developed based on the motion of the shank. This funding opportunity will be used for production and development costs, and testing the bionic ankle on two participants. A commercially available walk/run bionic ankle could be developed in 2.5 years with the support of this grant. PUBLIC HEALTH RELEVANCE: This research project develops a powered walk/run prosthetic ankle to restore able-bodied function to a below the knee amputee. Within the U.S. there are approximately 1.2 million people living with a lower limb amputation with 100,000 new cases each year.

描述(由申请人提供)： 这项提议将利用创新的技术，允许膝盖以下的截肢者使用单一动力假肢装置行走和跑步。目前被动假肢的使用者通常会消耗更多的能量，减少脚踝的运动和功率，增加步态不对称，导致关节和背部疼痛。使用机器人肌腱执行器增加脚踝力量将恢复近乎健全的功能，提高生活质量。将进行一项初步研究，为第二阶段的更大规模生物力学研究做准备。将根据小腿的运动开发一种新的运行控制器。这一资金机会将用于生产和开发成本，以及在两名参与者身上测试仿生脚踝。在这笔赠款的支持下，商业上可用的步行/奔跑仿生脚踝可以在2.5年内开发出来。 公共卫生相关性： 这项研究项目开发了一种电动行走/奔跑假肢，以恢复膝关节以下截肢者的健全功能。在美国，每年约有120万人接受下肢截肢，新增10万例截肢病例。
