Objectives : The primary purpose of this study was to examine the effect of manual acupuncture at the LI_4_, ST_36_ and LR_3_ on normal human EEG (Electroencephalogram). And the secondary purpose of this study was to analyze the relationships between the change of EEG wave form using correlation analysis.
Methods : 32 channel EEG measurement was carried out in 25 healthy participants (23 males and 2 females). EEG was measured for 21 minutes including 15 minutes of retention time. In this study, power spectrum was used as a measure of complexity. Statistical analysis was performed using Spearman correlation.
Results : The results were as follows;
1. In C4, O1, Fz, Pz, Cz, FCz, CP4, FC4, TP7, FT7 among 32 electrodes, δ, θ and β wave increased during 0-3 time intervals, and especially in case of TP7, FT7 α wave spontaneously decreased during 12~15 time intervals in manipulation group.
2. Between θ and β wave and θ and δ wave, there was statistically significant positive correlation in C4, O1, Fz, Pz, Cz, FCz, CP4, FC4, TP7, FT7 according to Spearman correlation analysis.
3. Between α and β wave, there was statistically significant positive correlation in TP7, FT7 according to Spearman correlation analysis.
Conclusions : These results suggest that TP7 and FT7 could be typical electrodes representing change of EEG after manipulated acupuncture at the LI_4_, ST_36_ and LR_3_ . The relationships between the change of EEG wave form appear to have statistically significant positive correlation between θ and β wave, θ and δ wave and α and β wave.
