DESCRIPTION (provided by applicant): The Advanced Biofidelic Lower Extremity Kids prosthesis (ABLE Kids) project will advance the state-of-the-art of pediatric prosthesis systems by advancing the demonstrably successful Phase I device and refining it into an ultracompact and lightweight form factor suitable for pediatric use. Through the support of the Shriner's Hospitals in Salt Lake City, UT and Shreveport, LA, numerous prosthetists, and with the consultation of cutting edge researchers at Clarkson University, a highly adaptive device will be produced and commercialized suitable for childhood amputees with both traumatic and congenitial deficiencies. Specifically, ABLE Kids will result in a modular, microprocessor controlled, mesofluidic ankle joint that dynamically makes ankle control adjustments needed to optimize the dynamic function and safety of a child's prosthesis. Additionally, advanced algorithms will be developed to optimize the performance of non microprocessor controlled knees by adjusting ground reaction forces to optimize trigger point and release for knees in transfemoral pediatric subjects. PUBLIC HEALTH RELEVANCE: This project will advance the state of the art for lower limb prostheses for children. Novel mesofluidic technology and control algorithms will be used to make miniaturized microprocessor controlled hydraulic ankle joint system. The result will be improved function and decreased problems for children with limb loss.

描述(由申请者提供)：先进的Biofidelic小腿儿童假体(Able Kids)项目将推进儿科假体系统的最先进技术，通过改进明显成功的第一阶段设备并将其改进为适合儿科使用的超紧凑和轻量化的外形因素。通过位于德克萨斯州盐湖城和洛杉矶什里夫波特的施林纳医院的支持，众多假肢医生以及克拉克森大学尖端研究人员的咨询，将生产一种高度适应性的装置，并将其商业化，适用于患有创伤和先天缺陷的儿童截肢者。具体地说，Able Kids将产生一个模块化、微处理器控制的介流体踝关节，它可以动态地进行脚踝控制调整，以优化儿童假体的动态功能和安全性。此外，还将开发先进的算法，通过调整地面反作用力来优化非微处理器控制的膝关节的性能，以优化经股动脉的儿科受试者膝盖的触发点和释放。 公共卫生相关性：该项目将推动儿童假肢技术的发展。新型介观流体技术和控制算法将被用于制造小型化的微处理器控制的液压踝关节系统。其结果将是改善功能，减少肢体缺失儿童的问题。
