摘要
目的:针对帕金森患者的静息性震颤,设计了可穿戴式多模式电刺激辅助治疗震颤抑制系统。方法:系统通过上位机与主控芯片STC89C52进行通信,控制极性转换电路产生参数可连续调节的双极性电刺激脉冲,之后对所得脉冲波形进行快速傅里叶变换(Fast Fourier Transform, FFT)分析。结果:通过实验验证了系统输出脉冲在12~40 V,频率为30~71 Hz,系统具有稳压的特点,且脉冲波形无毛刺和尖峰脉冲,对人体刺激性较小,震颤抑制系统产生的刺激脉冲可以起到对帕金森患者辅助治疗的作用。结论:震颤抑制系统可通过手动调节电刺激参数,达到辅助治疗的效果,为帕金森患者的震颤抑制提供了理论基础。
Objective: A wearable multi-mode electrical stimulation system was designed to assist the treatment of tremor suppression in patients with Parkinson’s disease. Method: The system communicates with the main control chip STC89C52 through the upper computer, and controls the polarity conversion circuit to generate the bipolar electric stimulation pulse with continuously adjustable parameters. Then, the waveform of the pulse is analyzed by Fast Fourier Transform (FFT). Results: The system has the characteristics of voltage stability when the output pulse is 12~40 V and the frequency is 30~71 Hz. And the pulse waveform has no burr and spike pulse, which is less irritating to human body. Stimulation pulses produced by the tremor suppression system can be used as an adjunct to Parkinson’s disease. Conclusion: Tremor suppression system can achieve the effect of adjuvant therapy by manually adjusting the parameters of electrical stimulation, providing a theoretical basis for tremor suppression in Parkinson's disease patients.
