针对脑卒中后肢体功能障碍、褥疮及疼痛,分析了临床上常用的治疗参数,设计了多模式电刺激治疗系统。该系统通过触摸屏与主芯片STM32L152RCT6进行通信,控制升压和极性转换电路产生幅值、频率及脉宽均可连续调节的双极性电刺激脉冲,验证了系统的稳定性和镇痛的效果。通过试验验证了系统能稳定工作,且电脉冲幅值与电阻值的变化无关,且能提高受试者的疼痛阈值。能产生临床使用的电刺激疗法的各类参数,有利于临床实验和相关科研的开展。电刺激技术能够缓解人体疼痛,提高疼痛阈值。

Design and study of multi-mode rehabilitation system based on electrical stimulation technology

Aiming at the post-stroke limb dysfunction, decubitus and pain, the clinically used treatment parameters were analyzed and a multi-mode electrical stimulation treatment system was designed. This system was designed to communicate with the main chip STM32L152RCT6 through the touch screen. Bipolar electrical stimulation pulses with continuous adjustment of amplitude, frequency and pulse width were generated by controlling the boost and polarity conversion circuits which verifies the stability and analgesic effect of the system. It is verified by experiments that the system can work stably, and the amplitude of the electrical pulse is independent of the change of the resistance value. It can also improve the pain threshold of the subject. Various clinically used parameters for electrical stimulation therapy can be provided by the system, which are conducive to the development of clinical experiments and related studies. Electrical stimulation technology can alleviate human pain and increase pain threshold.
