Magnetic fields are widely considered as a method of treatment to increase the therapeutic effect when applied to acupoints. Hence, this study proposes a new method which creates significant stimulation of acupoints by using weak magnetic fields. We conducted this experiment in order to confirm the effect on the activation level of the autonomic nervous system by measuring pupil sizes in cases of stimulation by using manual acupuncture and electromagnetic acupuncture (EMA) at BL15. We selected 30 Hz of biphasic wave form with 570.1 Gauss. To confirm the biopotential by the magnetic flux density occurring in EMA that affected the activation of the autonomic nervous system, we observed the biopotential induced at the upper and the mid left and right trapezius. We observed a significant decrease in pupil size only in the EMA group (p < 0.05), thus confirming that EMA decreased the pupil size through activation of the parasympathetic nerve in the autonomic nervous system. Moreover, we confirmed that the amplitude of the biopotential which was caused by 570.1 Gauss was higher than ±20 μA. Thus, we can conclude that EMA treatment successfully activates the parasympathetic nerve in the autonomic nervous system by inducing a biotransformation by the induced biopotential.
当应用于穴位时，磁场被广泛认为是一种提高治疗效果的治疗方法。因此，本研究提出了一种利用弱磁场对穴位产生显著刺激的新方法。我们进行了这项实验，通过测量在BL15处使用手动针刺和电磁针刺（EMA）刺激时的瞳孔大小，来确认对自主神经系统激活水平的影响。我们选择了频率为30Hz、磁通密度为570.1高斯的双相波形。为了确认EMA中产生的磁通密度影响自主神经系统激活的生物电位，我们观察了左右斜方肌上部和中部诱导的生物电位。我们仅在EMA组中观察到瞳孔大小显著减小（p<0.05），从而证实EMA通过激活自主神经系统中的副交感神经降低了瞳孔大小。此外，我们证实由570.1高斯引起的生物电位幅度高于±20μA。因此，我们可以得出结论，EMA治疗通过诱导生物电位引起生物转化，成功激活了自主神经系统中的副交感神经。
