[Development of a testing device for knee joint kinematics parameters of patients with strokes]

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 C+ + MFC frame and shared database 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.
