等速肌张力测试系统的开发

Development of Isokinetic Muscle Tone Testing System

针对帕金森病患者的肌张力障碍,该文设计了一种新型等速肌张力测试系统。该系统包括机械装置、数据采集单元和上位机数据处理分析软件。其中机械装置包括手臂支撑装置、安全限位装置、高度调节装置等;数据采集单元由力矩传感器模块、电机控制模块、数据通信模块等组成,用于控制手臂进行等速运动并将传感器的模拟信号转换成数字信号实时传输到上位机;上位机数据处理分析软件采用USB接口传输数据,基于VC++程序开发,完成数据处理、显示、存储及报表生成等功能。实验结果表明:设计的等速肌张力测试系统安全可靠,不仅能够较好地评估帕金森患者的肌张力异常程度,还能应用于辅助肌张力患者的康复训练,具有较强的可扩展性。

A new type of isokinetic muscle tone testing system was designed for the Parkinson’s patients with dysmyotonia. The system consists of a mechanical device, a data acquisition unit, and a data processing and analyzing software. The mechanical device comprises an arm supporting device, a safety limiting device and a height adjusting device. Data acquisition unit, composed of a torque sensor module, a motor control module, a data communication module, and so on, is used to control the arm at constant speed and convert the sensor’s analog signal into digital signal, then the signal is transmitted to the computer in real-time by USB interface. The data processing and analyzing software, developed by VC++, has finished the data processing, display, storage, generated the reports, et al. The experimental results show that this system is reliable and safe, not only can evaluate the degree of abnormal muscle tone in Parkinson’s patients, but also can be used in the rehabilitation training of patients with dysmyotonia, which has strong expansibility.
