资料介绍

目的:设计一种功能性电激励(FES)信号发生器,主要用于刺激患者截瘫部位以促进自身部分运动功能的恢复。方法:硬件系统基于AT89C52MCU和DAC0832数模转换芯片。通过分析常见波形和动物实验中提取出的控制运动的神经信号波形的时域特征来设计单片机程序,实现软硬件协同之后,可产生预期波形作为治疗仪的信号源。结果:经过测试,该信号发生器给出了各时域波形图,包括如正弦波、矩形波、三角波等常见信号,以及与控制运动相关的神经信号波段。结论:与传统的信号发生器[1]相比,该信号发生器结构简单,功能齐全,成本低廉。并且,记录与控制运动相关的神经信号,通过数据分析编入程序共同作为运动功能康复治疗仪的信号源,这更有利于诱发协调的肢体动作,减少肌疲劳。

Objective: In order to promote paraplegia patients’ recovery of part of motor function, we design this functional electrical stimulation(FES) signal generator. Method: The hardware system consists of main control unit, conversion unit and output unit,with AT89 C52 MCU and DAC0832 digital analog converter as the analyzing the time domain characteristics of common waveforms and the neural signals which relate movement from animal experiments, we design SCM program to cooperate hardware design with software, and then the expected waveforms can be produced as signal sources of therapeutic apparatus. Results: After tests, this signal generator can produce each signal in the time domain waveform, including common waveforms such as sine wave,rectangular wave, triangular wave signal, and neural signal bands relating clusion: Compared with the traditional signal generators[1], the signal generator has the advantages of simple structure, complete functions, low cost, convenient use. At the same time, using the neural signals which relate movement from animal experiments as signal sources of motor function rehabilitation treatment instrument is beneficial to induce the coordinated movement and reduce muscle fatigue.
