介绍了利用智能化方式评定腕关节的活动范围.通过矩阵式分布的光敏二极管,将有无光照信号转化为高低电平输入单片机,并将此数据以串口通信方式发送到上位机.先后采集手腕起始与转动后的数据,通过软件处理以图像形式显示,并计算出腕关节转动的角度,同时给出评价.本系统可以协助医护人员更好地对病人情况进行分析、诊断与护理.%The intellectualized way for evaluating the joint range of motion was introduced. With the light-sensitive diode placed as the matrix form, the light signal was changed into the voltage which would be collected into a single-chip. Then the single-chip sent these data to the computer by serial connection way. The initial data and successive data of the moved wrist were collected. After using software to display the data in graphic form, the computer calculated the angle of the moved wrist, and evaluated the patients' condition at the same time. This system will assist clinicians to make accurately and timely evaluation to the patients' rehabilitation.
