Preliminary experiments were carried out to investigate the feasibility of using an electroencephalogram and heart rates to evaluate the efficacy of finger acupressure on the key points of planta pedis (both soles). Continuous electroencephalograms were recorded from 19 electrodes based on the International 10-20 electrode placement system on 22 university students (21+/-2.3 years). Spectral power changes were obtained at each electrode site. The power of the alpha1 frequency range (8-10 Hz) increased slightly during acupressure although no statistical significance was observed, while heart rates decreased in all subjects (p<0.05). Cerebral cortex asymmetry in the spectral power changes was not clearly observed during the right and left sole acupressure. This preliminary study suggests that a classification of subjects is necessary in understanding brain wave data during acupressure on soles.
开展了初步实验，以研究使用脑电图和心率来评估指压足底（双脚）关键点的疗效的可行性。基于国际10-20电极放置系统，从22名大学生（21±2.3岁）的19个电极记录连续脑电图。在每个电极部位获得频谱功率变化。指压过程中，α1频率范围（8-10Hz）的功率略有增加，尽管未观察到统计学意义，而所有受试者的心率均下降（p<0.05）。在左右足底指压过程中，未清楚观察到频谱功率变化中的大脑皮质不对称性。这项初步研究表明，在理解足底指压过程中的脑波数据时，有必要对受试者进行分类。
