Computerized Orthotic Prescription System - COPS

描述(申请人提供)：踝足矫形器(AFO)的僵硬和对齐是其最佳功能和适合性的关键因素。AFO的僵硬和对齐不当可能会导致中风患者的关节疼痛、步行功能降低和医疗并发症增加。因此，由其僵硬和对齐决定的AFO适合性的相对质量在AFO患者的日常生活中是最重要的。这项拟议工作的目标是创建和演示一种新的AFO系统，称为计算机化矫形处方系统(COPS)，它帮助矫形师优化中风患者AFO的动态功能。COPS辅助矫形师动态调整AFO刚度和静态对准AFO。警察的概念如下。它由仪表化鞋垫、带有磁流变液制动关节的可调式AFO和软件组成。安装在AFO中的倾斜仪用于静态地将对齐调整到定义的角度。仪表式鞋垫的设计是为了计算穿戴AFO时作用在脚踝关节上的外部力矩。该软件随后分析从鞋垫无线发送的数据，并就其硬度的动态变化向矫形师提供建议。在这项研究中，我们将改进原型的仪表式鞋垫，并将其整合到可调谐AFO中，开发软件的刚度预测算法，并在临床上验证COPS的概念。僵硬预测算法的开发将基于我们在上一个项目：计算机化假体对准系统(COMPAS)上的经验。通过输入已知刚度偏差的数据，建立预测不适当刚度的模糊逻辑算法。最后，概念验证将涉及对COPS的有效性的调查，以检测次最佳僵硬条件，以及COPS向矫形师指示适当补救的能力。如果成功，COPS将给矫形师和患者带来信心，并显著减少AFO僵硬和对齐调整的迭代过程的时间。 公共卫生相关性：该项目将帮助和改进中风患者的踝足矫形器(AFO)处方。该技术将客观地指导矫形师确定AFO的最佳僵硬和对齐，以最大限度地发挥其针对每个患者的动态功能。

DESCRIPTION (provided by applicant): Stiffness and alignment of ankle-foot orthoses (AFOs) are essential factors for its optimal function and fit. Improper stiffness and alignment of an AFO may induce joint pain, reduced ambulatory function, and increased medical complications for patients with stroke. As a consequence, the relative quality of AFOs fit determined by its stiffness and alignment is of paramount concern in the daily lives of patients ambulating with an AFO. The objective of the proposed work is to create and demonstrate a novel system for AFOs called the Computerized Orthotic Prescription System (COPS), which assists orthotists to optimize the dynamic function of AFOs for patients with stroke. COPS assists orthotists in tuning the AFO stiffness dynamically and aligning the AFO statically. The concept of the COPS is as follows. It consists of an instrumented insole, a tunable AFO with a magnetro-rheologic fluid brake joint and software. The inclinometer incorporated within the AFO is used to tune alignment to a defined angle statically. The instrumented insole is designed to calculate the external moments acting on the ankle joint while wearing the AFO. The software subsequently analyzes the data sent wirelessly from the insole and gives recommendations to orthotists on its stiffness change dynamically. In this study, we will refine the prototype instrumented insole and incorporate it into the tunable AFO, develop a stiffness prediction algorithm for the software, and clinically test the proof of concept of COPS. Development of the stiffness prediction algorithm will be based on our experience on the previous project: the Computerized Prosthesis Alignment System (Compas). The fuzzy logic algorithm for prediction of improper stiffness will be developed through input of data collected for known stiffness deviations. Finally, proof of concept will involve the investigation of the effectiveness of COPS to detect sub-optimal stiffness conditions and the ability of COPS to indicate appropriate remediation to the orthotist. If successful, COPS will give confidence to both orthotists and patients and significantly reduce time for the iterative process of stiffness and alignment tuning an AFO. PUBLIC HEALTH RELEVANCE: This project will assist and improve the prescription of ankle-foot orthoses (AFOs) for patients with stroke. The technology will objectively guide the orthotists to determine the optimal stiffness and alignment of AFOs to maximize their dynamic function for each individual patient.
