DESCRIPTION (provided by applicant): Prosthetics Our goal is to create a "transtibial prosthesis in a kit" that can be inexpensively manufactured using modern technology and advanced polymer materials. This system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or labs. Such a system alleviates the many steps involved with conventional prosthesis construction which is costly and labor intensive. The primary market for the proposed prosthetic system is impoverished third world countries. The market for such a system is large and consists of foreign healthcare organizations and ministries, the World Health Organization, and the U.S. Military which frequently supports humanitarian missions. A secondary market is in the early rehabilitation of amputees when the limb is changing size and shape in more economically advanced nations. Transtibial amputations due to trauma and dysvascular diseases are the most commonly performed levels of amputation in this country and worldwide and are the focus of this project. Our four year collaboration with Advanced Design Concepts (ADC) engineering firm has been quite successful to date in developing our preliminary prototype design. Continued collaboration with the principal business interest in this study, "iFIT Prosthetics, LLC" will enable us to develop the second generation prosthetic system. In this project, our aims are; i) to design and build the next generation prototype transtibial prosthetic system building on our experience and using a focus group of amputees for consumer input, ii) to conduct a pilot feasibility study on 10 volunteer subjects using biomechanics testing and quantitative surveys, and iii) to derive a final prototype and retest it using finite element analyses in preparation for ISO testing and commercialization. The results of this STTR project could change the way in which lower limb prostheses are provided in underdeveloped nations. The field of lower limb prosthetics can benefit greatly from advanced materials and fabrication techniques. Such innovations hold considerable promise to advance the science and practice of rehabilitation for these individuals. PUBLIC HEALTH RELEVANCE: Prosthetics Our company's goal is to create a "transtibial prosthesis in a kit" that can be inexpensively manufactured using modern technology and advanced polymer materials. This system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or facilities. Such a system will benefit amputees in impoverished countries as well as amputees in economically advanced nations. This innovative, highly-functional alternative to the current state of prosthetic fabrication holds great potential to advance the quality of life for amputees worldwide.

描述（由申请人提供）：假肢我们的目标是创建一个可以使用现代技术和先进的聚合物材料来廉价制造的“套件中的transibial假体”。该系统将立即适合残留的肢体，并在没有专门工具或实验室的情况下对准最佳步态。这样的系统减轻了与常规假体构建有关的许多步骤，这些步骤是昂贵和劳动力密集的。拟议的假肢系统的主要市场是贫困的第三世界国家。这种系统的市场很大，包括外国医疗保健组织和政府部门，世界卫生组织以及经常支持人道主义任务的美国军方。当肢体在更经济高级的国家的规模和形状变化时，二级市场是在早期恢复截肢者的康复中。由于创伤和血管性疾病引起的跨态截肢是该国和全球最常见的截肢水平，并且是该项目的重点。我们与高级设计概念（ADC）工程公司的四年合作在开发我们的初步原型设计方面非常成功。在这项研究中，继续与主要业务兴趣合作，“ IFIT ProSthetics，LLC”将使我们能够开发第二代假体系统。在这个项目中，我们的目标是； i）在我们的经验上设计和建立下一代原型训练型假体系统，并使用截肢者进行消费者输入的焦点，ii），ii）对使用生物力学测试和定量调查的10个志愿者进行试验性可行性研究，以及III，以及III）来得出最终的原型和验证元素的遗传分析，以获取有限的材料和iSONALEKITITION和ISOPORITION ANSKITITION in ISONITITINE in ISONITITINE in ISONITITINE in ISOTITITION和ISO ANSKITES中。该STTR项目的结果可能会改变欠发达国家提供下肢假体的方式。下肢假肢的领域可以从高级材料和制造技术中受益匪浅。这种创新具有巨大的希望，可以推动这些人的科学和康复实践。 公共卫生相关性：假肢我们公司的目标是在套件中创建一个“务实的假体”，可以使用现代技术和先进的聚合物材料来廉价地制造。该系统将立即适合残留的肢体，并在没有专门工具或设施的情况下对准最佳步态。这样的系统将使贫困国家以及经济高级国家的截肢者受益。这种创新的，高度功能的替代方案是当前假肢制造状态的巨大潜力，可以推动全球截肢者的生活质量。
