Effects of phong tri point electro - acupuncture in electroencephalogram

ABSTRACT

By1 time and 8 times , electroacupuncture (EA) was performed in and out of Phongtri site (GB20) of 55 healthy persons aged 20-27 years. Out of GB20, EA did not make frequency, amplitude and EEG indices changed in comparing with those before acupuncture, while in GB20 site, EA created the changes in frequency, amplitude and EEG indices in occipital and temporal areas. Upon EA , alpha wave index increased in average 14%, amplitude increased by 4 microV; beta wave index reduced by 2% in average, amplitude reduced by 3 microV. After electro- acupuncture theta and delta waves reduced 4% in average and amplitude reduced 3 microV in average
