两种佛家静功脑电近似熵及复杂度的比较

Comparative study of EEG approximate entropy and vomplexity on two buddhist qigong

目的:比较习练不同佛家静功时的的脑电差异。方法:选取持咒组与念佛组各12例,脑电采集分为练功前、练功中、练功后3个阶段,运用近似熵及复杂度2种方法分析其脑电特征,采用t检验比较比较组间差异。结果:练功过程中念佛组Fp1-A1、Fz-A1、Fp2-A2、F7-A1、F3-A1、FCz-A1、F4-A2、T3-A1、C1-A1、FCz-A2、CPz-A2、C2-A2、C4-A2、T4-A2、Pz-A1、P4-A2、T6-A2导联的近似熵显著大于持咒组(P<0.05),念佛组Fp1-A1、Fz-A1、Fp2-A2、F7-A1、F3-A1、FCz-A1、F4-A2、T3-A1、C1-A1、FCz-A2、C2-A2、C4-A2、T4-A2、T5-A1、P4-A2、T6-A2导联的复杂度显著大于持咒组(P<0.05),结论:念佛状态的脑电近似熵及复杂度显著大于持咒状态。

Objective： To compare the differences of the practice＇s EEG of different Buddhist Qigong.Methods： To collect the data of 12 mantra cases and 12 chanting Buddha cases,including before practice,in practice and after practice three State.Using the methods of approximate entropy and complexity to analysis the difference of EEG,and using T test to compare the difference between groups.Results： Before the state of practice the numerical value of approximate entropy of chanting Buddha group in channel Fp1-A1,Fz-A1,Fp2-A2,F7-A1,F3-A1,FCz-A1,F4-A2,T3-A1,C1-A1,FCz-A2,CPz-A2,C2-A2,C4-A2,T4-A2,Pz-A1,P4-A2,T6-A2 are much larger than that of mantra group（P0.05）.Before the state of practice the numerical value of complexity of chanting Buddha group in channel Fp1-A1,Fz-A1,Fp2-A2,F7-A1,F3-A1,FCz-A1,F4-A2,T3-A1,C1-A1,FCz-A2,C2-A2,C4-A2,T4-A2,Ts-A1,P4-A2,T6-A2 are much larger than that of mantra group（P0.05）.Conclusion： The numerical value of approximate entropy and complexity during chanting Buddha state is much larger than that of mantra state.
