- Abstract: Objective To analyze the signal diffusion in the body during electroacupuncture treatment of myasthenia, thereby improving the effect of signal array on body stimulation. Methods Based on the image data set of Chinese digital human right arm, a finite element simulation geometric model for analyzing the therapeutic effect of electroacupuncture physiotherapy was developed and then import into finite element simulation software. A theoretical model of electrical signal transmission in electroacupuncture physiotherapy was established using finite element modeling method. The positive and negative electrodes of the electroacupuncture were input with current signals with carrier frequencies of 1, 2 and 5 kHz and amplitudes of ±20 mA and -5 mA, so as to analyze the transmission mechanism of the signal in the arm. Results The simulation analysis shows that the maximum coupling voltage of 10 V was generated near the positive electrode, which was almost harmless to human body, and that an action area with a radius of about 1 cm would be formed around the positive electrode, which was the action area of physiotherapy. Meanwhile, by analyzing the distributions of potential and current on the inner axis of the arm, it was found that due to the effects of frequency increase on the tissue impedance, the tissue capacitance effect became more and more obvious, and the coupling potential declined gradually, but the electric current distribution, the key factor of physiotherapy, was hardly affected. Conclusion The increase of stimulation frequency will reduce the coupling potential, and the therapeutic effect will not be affected. Therefore, the hurt of coupling potential to human body can be reduced by increasing the frequency in the treatment.
