【摘要】：随着世界各国老龄化问题的日益突出,脑卒中患者不断增加,辅助康复医师对患者进行康复训练的上肢康康复机器人系统研究成为热点。现阶段康复机器人系统研究更集中在机械设计及运动控制,针对康复机器人系统结合医学理论的上肢康复综合评价方法的研究还很不成熟,上肢康复综合评价系统的设计与实现尚不多见。本文针对上肢康复机器人评价存在的实际问题,应用直觉模糊集理论设计一种上肢康复综合评价方法,实现主客观指标的综合自动评价,并基于该方法进行系统设计与开发。主要工作如下：(1)结合上肢临床康复医学知识与五自由度上肢康复机器人训练特点,确定了康复评价指标体系,给出了各项评价指标的采集方法、量化标准和转化为直觉模糊集表示方法。(2)建立了基于直觉模糊集理论的上肢康复综合评价模型。针对评价指标之间的关联现象表达问题,运用模糊测度集理论解决；针对定量型实测数据的评价矩阵贡献度求取问题,采用区间度估计及矩阵对应思想解决；针对定性型评价指标贡献度求取问题,采用改进型层次分析方法,解决了传统层次分析方法存在的次序不一致性问题、基本满意不一致性问题及元素缺失情况；针对多指标的综合分析问题,选取普适且有序集结的直觉模糊集Choquet算子对指标进行集结运算；针对多医师评价的矛盾不一致现象,提出一种基于直觉模糊集距离的方法解决。(3)基于上肢康复综合评价模型,设计和开发上肢康复综合评价系统。对评价模型的各个方法模块进行算法设计并运用C#、Matlab与C++语言混合编程。该系统实现对运动功能障碍、反射、疼痛、肩、肘、前臂、腕的康复程度评价及综合上肢康复评价,并将评价结果存入SQL数据库,方便医师对患者康复全程的各项指标进行跟踪记录。通过对实际患者进行评价测试实验,结果表明上肢康复评价系统所得到的评价结果同医师临床评价结果基本一致,验证基于直觉模糊集的上肢康复评价方法能够对患者进行全面、客观、多角度量化的康复评价,从而对康复训练起到指导和反馈作用。
[Abstract]:With the aging problem becoming more and more prominent in the world, the number of stroke patients is increasing, and the research of rehabilitation robot system for rehabilitation training of patients has become a hot spot. At present, the research of rehabilitation robot system is more focused on mechanical design and motion control. The research on the comprehensive evaluation method of rehabilitation robot system combined with medical theory is still immature. The design and implementation of a comprehensive evaluation system for upper limb rehabilitation is rare. Aiming at the practical problems in the evaluation of upper limb rehabilitation robot, this paper applies the theory of intuitionistic fuzzy set to design a comprehensive evaluation method of upper limb rehabilitation, which realizes the automatic evaluation of subjective and objective indexes, and designs and develops the system based on this method. The main work is as follows: (1) combined with clinical rehabilitation medical knowledge of upper limb and training characteristics of five-degree-of-freedom upper limb rehabilitation robot, the index system of rehabilitation evaluation is determined, and the collection method of each evaluation index is given. Quantification criteria and transformation into intuitionistic fuzzy set representation. (2) A comprehensive evaluation model of upper limb rehabilitation based on intuitionistic fuzzy set theory is established. The fuzzy measure set theory is used to solve the problem of the expression of correlation phenomenon among evaluation indexes, and the interval degree estimation and matrix correspondence thought are used to solve the problem of calculating the contribution degree of the evaluation matrix of the quantitative measured data. Aiming at the problem of determining the contribution degree of qualitative evaluation index, this paper adopts the improved analytic hierarchy process (AHP) method to solve the problem of order inconsistency, basic satisfaction inconsistency and missing elements of traditional AHP method. Aiming at the problem of comprehensive analysis of multiple indexes, the Choquet operator of universal and ordered aggregation of intuitionistic fuzzy sets is selected to assemble the indexes, and the contradictory phenomenon of multi-physician evaluation is analyzed. A method based on intuitionistic fuzzy set distance is proposed. (3) based on the comprehensive evaluation model of upper limb rehabilitation, a comprehensive evaluation system of upper limb rehabilitation is designed and developed. The algorithm of each method module of evaluation model is designed, and the mixed programming of C language and C # is used. The system can evaluate the degree of rehabilitation of motor dysfunction, reflex, pain, shoulder, elbow, forearm, wrist and comprehensive evaluation of upper limb rehabilitation. The evaluation results are stored in SQL database. It is convenient for doctors to track and record the indexes of patients during the whole course of rehabilitation. The results of the evaluation test on actual patients show that the evaluation results obtained by the upper limb rehabilitation evaluation system are basically consistent with the clinical evaluation results of physicians. It is verified that the evaluation method of upper limb rehabilitation based on intuitionistic fuzzy set can be used to evaluate the rehabilitation of patients comprehensively, objectively and quantitatively, thus providing guidance and feedback for rehabilitation training.
