A low cost and effective foot orthotics fabrication framework

项目摘要： 我们建议在这项SBIR的努力，开发一个直接的三维移动的成像为基础的足部矫形器 用于临床医生治疗和预防慢性疾病如糖尿病溃疡的优化系统， 排列不齐所提出的系统超越了传统的矫形器生产过程，因为它 允许临床医生从任何需要的位置直接方便地获取患者的3D足部结构， 姿势（负重、不负重或部分负重），提供全面的详细信息 对患者足部生物力学的影响，并通过有限元分析优化矫形设计。的 拟议的系统还允许通过3D打印机进行局部测试和改装， 矫正器设计，从而改善当今面临的顺应性问题。 建议的解决方案将产生以下影响和意义： 预防糖尿病足溃疡复发;更好的足部矫形器定制体验;更多 舒适的配合导致更好的顺应性;以及更低的治疗成本。 糖尿病足并发症是常见且昂贵的问题。约3030万 美国人，9.4%的美国人口患有糖尿病，根据美国科学院。 矫形器和假肢。在60岁以上的成年人中，约有四分之一患有糖尿病。随着人口老龄化， 预计在未来十年，这一群体的年增长率至少为7%。定制足部矫形器是 通常用于治疗和预防足部糖尿病复发。毫无疑问，发展一个 基于低成本和普适性移动的平台的足部矫形优化和快速成型方法 将对老年人，特别是中低收入患者产生重大影响。

Project Summary: We propose in this SBIR effort to develop a direct 3D mobile imaging based foot orthotics optimization system for clinicians to treat and prevent chronic conditions such as diabetic ulceration and malalignment. The proposed system leaps beyond the traditional orthotics production process, as it allows clinicians to directly and conveniently acquire patients' 3D foot structure from any needed postures (either weight bearing, non-bearing, or partial weight bearing), provides comprehensive details on patients' foot biomechanics, and optimizes orthotics design through finite element analysis. The proposed system also allows localized testing and refitting through a 3D printer, facilitating comfort orthotics design and thus improving the compliance issue faced today. The proposed solution will have the following impact and significance: facilitate effective prevention of the recurrence of diabetic foot ulcers; better foot orthotics customization experience; more comfort fit leading to better compliance; and lower treatment cost. Diabetic foot complications are common and costly problem. Approximately 30.3 million Americans, 9.4 percent of the U.S. population have diabetes, according to the American Academy of Orthotists and Prosthetists. In adults over age 60, about 1 in 4 have diabetes. With the aging population, this group is expected to grow at least 7% per year for the next 10 years. Custom foot orthotics are commonly used to treat and prevent the recurrence of foot diabetics. Undoubtedly, the development of a low cost and ubiquitous mobile platform based foot orthotics optimization and rapid prototyping method will have significant impact on the elderlies especially for the low and middle income sufferers.
