项目摘要

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): 该提案将利用创新技术,使膝盖以下截肢者能够使用单一动力假肢装置行走和跑步。被动假体装置的当前使用者通常消耗更多的能量;踝关节运动和动力减少;并且步态不对称增加,导致关节和背部疼痛。用机器人肌腱致动器增强踝关节力量将恢复接近健全的身体功能,提高生活质量。将进行一项试点研究,为第二阶段更大规模的生物力学研究做准备。基于刀柄的运动,开发了一种新型的运行控制器。这笔资金将用于生产和开发成本,并在两名参与者身上测试仿生脚踝。在这笔赠款的支持下,可以在2.5年内开发出一种商业化的步行/跑步仿生脚踝。 公共卫生相关性: 本研究计划开发一种动力行走/跑步假肢踝关节,以恢复健全的功能,膝盖以下截肢者。在美国,大约有120万人患有下肢截肢,每年有10万例新病例。
