DESCRIPTION (provided by applicant): With over 300,000 lower limb amputees in America, lower limb prostheses are a very important intervention to keep this population active and otherwise healthy. With nearly half of this population choosing not to use a prosthesis to replace their lost limb, there is a strong market need for better foot prostheses. Using novel technologies, the proposed prosthesis will duplicate the subtle motions and coordinations of the human foot. These motions will provide the amputees with improved gait mechanics. This improvement in gait will be seen in an oxygen consumption study, showing that users of this new prosthesis were able to ambulate with a lower energy cost per meter traveled, when walking at the same speed. Phase I first proposes to complete the designs described herein. These designs will then be subjected to rigorous bench testing, establishing that the prosthesis has more accurately modeled the biomechanics of the human foot. Bench testing will continue with fatigue testing, to ensure that the human subjects will able to safely use the novel prosthesis for a two week "break-in" period. Upon completion of this break-in period, the human subjects will participate in the oxygen consumption study mentioned above. The same technology explored in the design of this prosthesis can be applied to replace or augment every joint in the body, paving the way for broad advances in prosthetic and orthotic technology. These advances can then be applied to the military and transportation sectors.

描述（由申请人提供）：美国有超过 300,000 名下肢截肢者，下肢假肢是保持这一人群活跃和健康的非常重要的干预措施。由于近一半的人口选择不使用假肢来替代失去的肢体，因此市场对更好的足部假肢的需求非常强烈。使用新技术，所提出的假肢将复制人脚的微妙运动和协调。 这些动作将为截肢者提供改善的步态力学。这种步态的改善将在一项耗氧量研究中看到，该研究表明，当以相同的速度行走时，这种新型假肢的使用者能够以更低的每米移动能量成本行走。 第一阶段首先建议完成本文描述的设计。然后，这些设计将接受严格的台架测试，以确定假肢更准确地模拟了人脚的生物力学。台架测试将继续进行疲劳测试，以确保人类受试者能够在两周的“磨合”期内安全地使用新型假肢。磨合期结束后，人类受试者将参加上述耗氧量研究。 该假肢设计中探索的相同技术可用于替换或增强身体的每个关节，为假肢和矫形器技术的广泛进步铺平了道路。这些进步可以应用于军事和运输部门。
