本文介绍了穴位刺激的明显效果，用脑电图（EEG）的测量。本研究将24名无心脏病或神经系统疾病的受试者随机分为实验组和对照组，每组12人。进行类似的程序;受试者躺在床上，闭上眼睛10分钟作为基线。实验组针刺左手外关穴（TE 5）20 min，对照组不针刺。在针刺前、针刺刺激和针刺后刺激期间记录EEG。EEG电极位于T3、T4、O 1和O2位置。采用连续小波变换分析，将脑电信号分为delta（0.5-4 HZ）、theta（4-8 HZ）、alpha（8-13 HZ）和beta（13-30 HZ）频段，针刺刺激时，theta能量增加，在T3、T4、O 1、O2各电极点均有统计学差异。拔针后，T3和T4点的能量缓慢下降，并显示出明显的统计学差异。在针刺过程中，只有α能量有统计学差异，并且在T3点增加。针灸被证明能够影响脑电波，因为刺激可能改变了颅骨和头皮之间的组织，因此脑电波更容易被检测到。
This paper presents the evident effects of acupoint stimulation, using EEG (electroencephalogram) measurements. With acupuncture stimulation and the EEG measurement on the same meridian, EEG is able to accurately detect the effects of acupunctural point stimulation on brain waves.In this study, 24 subjects without heart or neural diseases were randomly separated into two groups of 12, named test and control groups. Similar procedures are performed; the subjects lay on a bed with eyes closed for ten minutes as the baseline. The test group received acupuncture at their Waiguan points (TE5) on their left hands for 20 minutes, while the control group did not. EEGs are recorded during pre-acupuncture, acupuncture stimulation and post-acupuncture stimulation periods. The EEG electrodes are at the T3, T4, O1 and O2 locations. Continuous wavelet transformation analysis is adopted; therefore, EEGs are divided into the following bands: delta (0.5-4 HZ), theta (4-8 HZ), alpha (8-13 HZ) and beta (13-30 HZ).During acupuncture stimulation, the theta energy is increased and had statistical differences at all electrode points, T3, T4, O1 and O2. Upon removing the needle, the energy at the T3 and T4 points slowly declined and revealed obvious statistical differences. During acupuncture, only alpha energy has been noted to have statistical difference and it was increased at the T3 point. However, the energy was decreased and had no statistical difference after five minutes.Acupuncture is proven to be able to affect brain waves, as the stimulation might have changed the tissues between the cranium and scalp; therefore, the brain waves are detected more easily.
