The aim of this study was to compare the influences of manual acupuncture, laser acupuncture, and electromagnetic field stimulation on the autonomic nervous system. We monitored the heart rate variability before and after stimulation to check the influence on the autonomic nervous system. The heart rate variabilities at low frequency (LF; 0.04-0.15 Hz) and high frequency (HF; 0.15-0.4 Hz) were analyzed to acquire LF/HF ratio. Xinshu (BL15) was selected as the stimulation point. Methods included manual acupuncture with a 1-cm depth and laser acupuncture at a wavelength of 660 nm and output power of 50 mW. An electromagnetic field of 2 Hz and 460 gauss (46 mT) was chosen. The LF and the LF/HF ratio were found to be lower in the manual acupuncture and the electromagnetic field groups, but to be higher in the laser acupuncture group. The HF was found to be lower in the laser acupuncture group, but higher in the manual acupuncture and the electromagnetic field groups. In conclusion, we found that manual acupuncture and electromagnetic field stimulation at BL15 activated the parasympathetic nervous system, whereas laser acupuncture at BL15 activated the sympathetic nervous system.
本研究旨在比较手动针刺、激光针刺和电磁场刺激对自主神经系统的影响。我们在刺激前后监测心率变异性，以检查对自主神经系统的影响。分析低频（LF；0.04 - 0.15Hz）和高频（HF；0.15 - 0.4Hz）的心率变异性，以获得LF/HF比值。选取心俞穴（BL15）作为刺激点。方法包括深度为1厘米的手动针刺、波长为660纳米、输出功率为50毫瓦的激光针刺。选择频率为2赫兹、强度为460高斯（46毫特斯拉）的电磁场。结果发现，手动针刺组和电磁场组的LF及LF/HF比值较低，而激光针刺组的较高。激光针刺组的HF较低，而手动针刺组和电磁场组的较高。总之，我们发现，在BL15处进行手动针刺和电磁场刺激可激活副交感神经系统，而在BL15处进行激光针刺可激活交感神经系统。
