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.

描述（由申请人提供）：踝足矫形器（AFOs）的刚度和对齐是其最佳功能和配合的基本因素。AFO不适当的僵硬和对齐可能会引起关节疼痛，降低运动功能，并增加中风患者的医疗并发症。因此，AFO的相对质量是由其刚度和对齐决定的，这是患者使用AFO行走时最关心的日常生活。本研究的目标是为afo创建并演示一种称为计算机矫正处方系统（COPS）的新型系统，该系统可以帮助矫形师优化中风患者的afo的动态功能。COPS帮助矫形师动态调整AFO刚度，静态调整AFO。cop的概念如下。它包括一个仪表鞋垫，一个可调的AFO与磁流变液制动接头和软件。在AFO内的倾角计用于静态地调整对准到定义的角度。仪表鞋垫设计用于计算佩戴AFO时作用于踝关节的外部力矩。该软件随后分析从鞋垫无线发送的数据，并根据其刚度的动态变化向矫形师提供建议。在本研究中，我们将改进原型仪器鞋垫并将其纳入可调谐AFO，为该软件开发刚度预测算法，并对COPS概念的临床验证进行测试。刚度预测算法的开发将基于我们之前项目的经验：计算机义肢对齐系统（Compas）。通过输入已知刚度偏差收集的数据，开发用于预测不适当刚度的模糊逻辑算法。最后，概念验证将涉及对cop检测次优刚度条件的有效性的调查，以及cop向矫形师指示适当补救措施的能力。如果成功，cop将给矫形师和患者带来信心，并显着减少AFO刚度和对准调整迭代过程的时间。
