In order to solve the problems of insufficient stimulation channels and lack of stimulation effect feedback in the current electrical stimulation system, a functional array electrode electrical stimulation system with surface electromyography (sEMG) feedback was designed in this paper. Firstly, the effectiveness of the system was verified through and human experiments. Then it was confirmed that there were differences in the number of amperage needed to achieve the same stimulation stage among individuals, and the number of amperage required by men was generally less than that of women. Finally, it was verified that the current required for square wave stimulation was smaller than that for differential wave stimulation if the same stimulation stage was reached. This system combined the array electrode and sEMG feedback to improve the accuracy of electrical stimulation and performed the whole process recording of feedback sEMG signal in the process of electrical stimulation, and the electrical stimulation parameters could change with the change of the sEMG signal. The electrical stimulation system and sEMG feedback worked together to form a closed-loop electrical stimulation working system, so as to improve the efficiency of electrical stimulation rehabilitation treatment. In conclusion, the functional array electrode electrical stimulation system with sEMG feedback developed in this paper has the advantages of simple operation, small size and low power consumption, which lays a foundation for the introduction of electrical stimulation rehabilitation treatment equipment into the family, and also provides certain reference for the development of similar products in the future.
为了解决当前电刺激系统中刺激通道不足和缺乏刺激效果反馈的问题，本文设计了一种具有表面肌电图（sEMG）反馈的功能阵列电极电刺激系统。首先，通过实验和人体实验验证了该系统的有效性。然后证实，个体之间达到相同刺激阶段所需的安培数存在差异，且男性所需的安培数通常少于女性。最后，验证了如果达到相同的刺激阶段，方波刺激所需的电流小于差分波刺激所需的电流。该系统结合了阵列电极和sEMG反馈，提高了电刺激的准确性，并在电刺激过程中对反馈的sEMG信号进行全过程记录，电刺激参数可随sEMG信号的变化而改变。电刺激系统和sEMG反馈共同作用，形成一个闭环电刺激工作系统，从而提高电刺激康复治疗的效率。总之，本文研制的具有sEMG反馈的功能阵列电极电刺激系统具有操作简单、体积小、功耗低等优点，为电刺激康复治疗设备进入家庭奠定了基础，也为未来同类产品的开发提供了一定的参考。
