气功激发经气过程中的肌电信号分析

MYOELECTRIC SIGNAL ANALYSIS IN PROCESS OF QIGONG PROMOTING MERIDIANS QI FLOW

为了进一步提高肌电信号的出现申及重复性和循经性，对自发气功、接受外发气功、针刺、留针、拔针等过程中，肌电发放的指标进行观察。结果显示，气功激发与针刺激发一致，均能出现四种不同类型的电位。其信号经功率谱分析，不论在自发气功、外发气功、针刺、留针时，均显示了经穴的相对谱功率高于左右两旁对照点。本实验通过功率谱的分析，提示针刺与气功作用于某一经穴时，沿经有能量的递增。气功与针刺一样，均能激发经气在经脉中周流，并且伴有一定的机能变化。给经络的研究增添了途径。

To further rise occurrence rate,repeatability andrunning along the merid-ians of myoelectric signd,the authors observed the occuring indexes of myoelectricity in theprocess producing qigong oneself, recieving qigong from other person,acupuncturing, main-taining the needles, taking out the needles and so on,The results showed that both qigongand acupuncture act on same provocation,and there occur four kinds of defferent electric po-tential.The signals,analysed wlth power spectrum,all showed that the opposite spectrumpower is higher than that of control poipts on the left and right. The experiment with analy-sis of power spectrum suggested when acupuncture or qigong acted on one point,the powerincreases progressively along the channel.Qigong is same as acupuncture to excite the chan-nel qi flowing in the channeis with some functioning change,which opened a new path for themeridians research.
