项目摘要

DESCRIPTION (provided by applicant): Foot ulceration is a diabetic complication estimated to result in over $1 billion worth of medical expenses per year in the United States alone. This multifaceted problem involves the response of plantar soft tissue to both external forces applied to the epidermis and internal changes such as vascular supply and neuropathy. Increasing evidence indicates that a combination of elevated external forces (pressure and shear) and altered tissue properties is of prime importance in the etiology of foot ulcers. The overall goal of this research is to develop a software package that will allow a clinician to see an accurate representation of three-dimensional (3-D) pressure and shear patterns on the plantar surface and identify areas of concern. Adaptable to a variety of measurement systems, the software uses innovative techniques to simultaneously visualize horizontal shear and vertical pressure. User options are available to enhance the visualization. Phase I results demonstrated that the visualization approach and prototype software can provide clear indication of both shear and pressure and the relationship between the two. Analysis algorithms have been created that identify location and magnitude of patterns of pressure and stress most likely to cause, pathological consequences to the skin. Orthopedic specialists have evaluated the software using baseline data from an experimental sensor array and simulated data in the same format and provided positive feedback regarding its utility. Based on these achievements, the Phase II work will focus on development of a complete software system for foot pressure and shear data visualization and analysis. Tasks include design of a flexible data model, an extensive suite of automated analysis tools, a comprehensive, easy-to use graphical user interface, and implementation of these features in a modular software architecture suitable for commercialization as either a turnkey system or a module for integration in a sensor vendor's existing software. Other Phase II activities include the establishment of licensing arrangements with one or more hardware vendors to use the software in conjunction with their systems. In conjunction with a new generation of measurement systems that monitor vertical pressure and horizontal shear forces, this software will emerge as a key tool for research in the etiology of foot ulcers and clinical evaluation of risk factors in diabetic patients.

描述（由申请人提供）：足部溃疡是一种糖尿病并发症，估计在美国，每年每年的医疗费用价值超过10亿美元。这个多方面的问题涉及足底软组织对表皮上应用的外部力和内部变化（例如血管供应和神经病）的反应。越来越多的证据表明，升高的外力（压力和剪切）和改变组织特性的结合在脚溃疡的病因中至关重要。这项研究的总体目标是开发一个软件包，该软件包将使临床医生能够在足底表面上准确地表示三维（3-D）压力和剪切模式并确定关注的领域。该软件可适应各种测量系统，使用创新技术同时可视化水平剪切和垂直压力。用户选项可用于增强可视化。第一阶段的结果表明，可视化方法和原型软件可以清楚地表明剪切和压力以及两者之间的关系。已经创建了分析算法，以识别压力和压力模式的位置和大小，最有可能对皮肤造成病理后果。骨科专家使用实验传感器阵列中的基线数据评估了该软件，并以相同格式的模拟数据，并提供了有关其效用的积极反馈。基于这些成就，第二阶段的工作将集中于开发完整的软件系统，用于脚压力和剪切数据可视化和分析。任务包括设计灵活的数据模型，广泛的自动分析工具的广泛套件，全面，易于使用的图形用户界面以及在适用于商业化的模块化软件体系结构中实现这些功能，作为交钥匙系统或传感器供应商现有软件中集成的模块。第二阶段的活动包括与一个或多个硬件供应商建立许可安排，以与其系统结合使用该软件。结合新一代的测量系统来监测垂直压力和水平剪切力，该软件将成为研究糖尿病患者病因的研究和临床评估危险因素的临床评估的关键工具。
