项目摘要

DESCRIPTION (provided by applicant): Current below the knee (trans-tibial) prostheses utilize elaborate springs and elastomers to store and dissipate energy during ambulation. While these designs are functional, they do not allow for energy input into the system which is necessary for reproducing normal human gait. This proposal investigates a new approach to the design of prostheses. The proposed bionic trans-tibial prosthesis uses a simple mechanism in conjunction with a spring and an electric motor that can more appropriately reproduce ankle moments while simultaneously keeping actuator power and energy consumption low. It is based upon preliminary theoretical research and a rough experimental prototype which shows such an approach is feasible. To ascertain if such a device is both feasible and functional from an amputee's perspective, a full working prototype will be created and compared to two standard dynamic response feet. The prosthesis will be tested on a modified test stand to adequately compare the performance of the prototype to these two standard feet and ensure amputee safety. The prototype prosthesis will then be fitted onto three test subjects who will ambulate with both the standard passive prosthesis and the powered prosthesis. During this testing, the research team will perform standard motion analysis to gain invaluable understanding of both the dynamic performance and the users' acceptance. The results of this experiment will be utilized to finalize the design which will then be tested under a subsequent R01 funding mechanism. PUBLIC HEALTH RELEVANCE: This research creates a new design paradigm of below-the-knee prostheses. These bionic prostheses will aid lower limb amputees to lead more active and productive lives.

描述（由申请人提供）：膝盖（跨式）假体以下的电流利用精致的弹簧和弹性体来存储和耗散能量，使能量在行走过程中。尽管这些设计是功能性的，但它们不允许在系统中输入能量，这是重现正常人体步态所必需的。该提案调查了一种新的假体设计方法。拟议的仿生式式临床假体使用了一种简单的机制与弹簧和电动机结合使用，该机制可以更适当地繁殖脚踝矩，同时使执行器的功率和能量消耗较低。它基于初步理论研究和一个粗略的实验原型，该原型表明这种方法是可行的。为了确定从截肢者的角度来确定这种设备是否可行且功能性，将创建一个完整的工作原型，并将其与两个标准的动态响应脚进行比较。假体将在改良的测试架上进行测试，以充分比较原型的性能与这两个标准脚，并确保截肢者的安全性。然后，原型假体将被安装在三个测试主题上，他们将同时使用标准的被动假体和动力假体进行行动。在此测试中，研究团队将执行标准运动分析，以获得对动态性能和用户接受的宝贵理解。该实验的结果将用于最终确定设计，然后在随后的R01资金机制下进行测试。公共卫生相关性：这项研究创建了膝盖下假体的新设计范式。这些仿生假肢将有助于下肢截肢者过上更积极和生产的生活。
