A low cost and effective foot orthotics fabrication framework

项目总结： 在这项SBIR工作中，我们建议开发一种基于直接3D移动成像的足部矫形术 优化临床医生治疗和预防糖尿病溃疡等慢性疾病的系统 不对准。拟议的系统超越了传统的矫形器生产工艺，因为它 使临床医生可以直接、方便地从任何需要的位置获取患者的3D足部结构 姿势(负重、非负重或部分负重)提供了全面的详细信息 对患者足部生物力学进行分析，并通过有限元分析优化矫形设计。这个 拟议的系统还允许通过3D打印机进行本地化测试和改装，便于舒适性 矫形器的设计，从而改善了当今面临的合规性问题。 拟议的解决方案将产生以下影响和意义：促进有效 预防糖尿病足部溃疡复发；更好的足部矫形器定制体验；更多 舒适贴合导致更好的依从性；并降低治疗成本。 糖尿病足并发症是常见且费用高昂的问题。约3,030万 根据美国科学院的数据，美国9.4%的人口患有糖尿病 矫形师和修复师。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， 这一群体预计在未来10年内每年至少增长7%。自定义足部矫形器有 常用于治疗和预防足部糖尿病患者的复发。毫无疑问，一种 基于低成本泛在移动平台的足底矫形优化及快速成型方法 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.
