DESCRIPTION (provided by applicant): This SBIR Fast-Track project will create an innovative new system for lower limb prosthetic alignment. Direct real-time measurements of force and moment at the base of the posthetic socket will be input for a newly developed algorithm in the Computerized Prosthetic Alignment System (ComPAS). It will assist prosthetists in the critical task of proper alignment. Previous investigators have clearly indicated a need for such a system, while noting the theoretical feasibility of using instrumentation to help a prosthetist improve prosthetic alignment. Previous efforts have not produced a successful system. Based on preliminary work we believe our new approach can successfully be developed into a clinically relevant, commercially viable system for lower limb prosthetic alignment. ComPAS will be an integrated system that is easy to use and intuitive to the prosthetist. It will be reasonably priced and we will seek a reimbursement code for its use so the system can 'pay for itself.' It will have near universal application in lower limb prostheses without special accommodation by the prosthetist and be used in both static and dynamic situations. The patient will be untethered and the system will be used in a normal office or clinic environment. Automated measurement and interpretation of gait parameters will be translated into user-friendly indicators that indicate to the prosthetist how to improve the alignment of the prosthesis. Phase I work will focus on building prototype hardware and software and demonstrating the efficacy of our approach. Phase II will refine the physical packaging and clinical capabilities, and will undertake more extensive scientific validation of the system. Phase I work will be comprised of the following four Specific Aims: 1. Design and Build Prototype ComPAS, 2. Refine Alignment Detection Algorithm, 3. Prosthetic Alignment Testing Using Proof of Concept ComPAS Prototype, 4. Clinical Review. Phase II work will build from the results and lessons learned from the Phase I project which focused on demonstrating proof of concept of a heuristic method for refining an algorithm to recognize misalignment from force and moment data collected at the base of the prosthetic socket during walking. Phase I feedback from clinical prosthetists and other experts in prosthetic gait will also be used to guide Phase II development. Phase II work will consist of the following 5 Specific Aims: 1. Design and Build Definitive ComPAS Hardware, 2. Design ComPAS Software Interface, 3. Refine Alignment Detection Algorithm, 4. System Testing, 5. Develop Proposed Criteria for Optimal Alignment. CYMA has an exceptional team with over 62 combined years of experience in the field of prosthetic research. We have specific knowledge of the field and the technical and business skills required for successful completion of the proposed development.

描述（由申请人提供）： 这个SBIR快速轨道项目将创建一个创新的新系统，以用于下肢假肢。 在计算机化的假体比对系统（Compas）中，将输入新开发的算法的后插座底部的力和力矩的直接实时测量。它将协助假肢制定适当的对齐的关键任务。 先前的研究人员清楚地表明，需要这种系统，同时指出了使用仪器来帮助假肢改善假体比对的理论可行性。以前的努力并未产生成功的系统。基于初步工作，我们认为我们的新方法可以成功地发展为临床上相关的，可行的下肢假体一致性系统。 Compas将是一个易于使用和直观的集成系统。它的定价合理，我们将寻求使用该系统的使用代码，以便系统可以“自行付款”。它将在下肢假体中几乎具有普遍的应用，而没有假肢的特殊住宿，并在静态和动态情况下使用。患者将不受束缚，系统将用于普通的办公室或诊所环境。步态参数的自动测量和解释将转化为用户友好的指标，这些指标向假肢指示如何改善假体的一致性。 第一阶段的工作将着重于构建原型硬件和软件，并展示我们方法的功效。第二阶段将完善物理包装和临床能力，并将对系统进行更广泛的科学验证。 第一阶段的工作将包括以下四个特定目标： 1。设计和构建原型Compas，2。精炼对准检测算法，3。使用概念证明Compas Prototype的假肢对准测试，4。临床综述。 第二阶段的工作将从第一阶段项目中学到的结果和经验教训，该项目的重点是展示启发式方法的概念证明，以精炼算法，以识别步行过程中在假体插座基础上收集的力量和时刻数据中的未对准。 临床假肢和其他假体步态专家的第一阶段反馈也将用于指导第二阶段的发展。 第二阶段的工作将包括以下5个具体目标： 1。设计和构建确定的Compas硬件，2。设计Compas软件接口，3。精炼对准检测算法，4。SystemTesting，5。制定建议的标准以进行最佳对齐。 Cyma拥有一支杰出的团队，在假体研究领域拥有超过62个综合的经验。 我们对成功完成拟议开发的领域有具体的了解以及所需的技术和业务技能。
