Abstract:
Abstract: Objective To analyze the electrical signal transduction of electronic analgesic apparatus in the arm muscle, thereby providing a theoretical basis for analgesia elicited by electrical stimulation. Methods In combination with the human anatomy and histological structure, the numerical simulation finite element model of electronic analgesic apparatus was established using the circular truncated cone, cylinder and ellipsoid as geometric entities in COMSOL Multiphysics 5.5 finite element simulation software, and the current signals with carrier signals of 100 kHz, 1 MHz and 10 MHz and the amplitude of ±20 mA were injected in the frequency domain environment for analyzing the transduction mechanism of electrical signal in the arm. Results With the continuous increase of carrier frequency, the skin effect became more and more obvious, and the signal was more concentrated at the part where the electrode contacted the skin, and the diffusion inside the volume conductor would lose consistency. At 100 kHz, as the communication distance from the electrode center gradually increased, the signal diffusion in the arm became more and more well-distributed. Conclusion For muscle soreness treatment with the electronic analgesic apparatus, the higher the communication frequency is, the more difficult it is for the signal to enter the body, and the worse the signal consistency is. Therefore, during electronic analgesia, the signal electrode should be arranged near the analgesic target area as much as possible.
