脑卒中患者膝关节运动参数测试仪的研发

Development of a Testing Device for Knee Joint Kinematics Parameters of Patients with Strokes

本文开发了一种用于检测脑卒中患者膝关节运动能力的多参数测试仪。该仪器利用Auto CAD设计膝关节角度测试装置,利用多功能数据采集卡实现对传感器数据的采集,由上位机进行关节角度、角速度等参数的定量检测与分析。软件系统采用Visual C++MFC框架开发,利用Access共享数据库实现患者信息存储,ADO技术实现数据库与软件系统的互联。经对20名正常人进行初步测试,各参数的组内相关系数(ICC)均大于0.8,表明仪器具有良好的可靠性。

This article is aimed to present a design of a testing device for knee joint kinematics parameters of patients with strokes. We used Auto CAD to design the knee joint sensor device, and applied multifunction data acquisition card to collect sensor data. Then we transferred the data to the computer to quantitatively detect and analyze the joint angle, angular velocity and other parameters. The software system used Visual CA--4-MFC frame and shared data- base Access, and used ADO technology to realize the collection between the software system and patient information system. After a preliminary test of 20 healthy subjects, the result showed that intraclass correlation coefficient （ICC） was more than 0. 8, indicating a good reliability of the instrument.
