Background : Recently a discussion about Qi including a study about the effect or the theory of acupuncture is getting prevailing in various angles. In most of studies about acupuncture stimulus, 'Filiform acupuncture'(毫鍼) is used. A study about Nine kinds of acupuncture(九鍼), except 'Filiform acupuncture'(毫鍼) has not been reported yet, and there is no study about using a special acupuncture made for controling Qi either. Objectives : 'Dong Chu Gold Chim(DCG-chim, 東樞金鍼)' can be used for patients who are scared of a pain because it is a medical Qi-gong tool and non-invasive stimulus one. To assess a effect of Qi-gong operation using DCG-chim objectively Methods : The present study was performed to elucidate the effects of DCG-chim stimulation of an acupuncture point Baihui($GV_{20}$) on the Electroencephalogram(EEG). Twenty healthy subject were treated with DCG-chim one time accompanied by the light and vertical pressure and EEG were measured during five minutes for three times (before, during and after treatment). The EEG results of DCG-chim treatment were compared with those of 'Filiform acupuncture(毫鍼)'. Results : EEG power spectra changed significantly after both kind of acupuncture stimulation. Significant increase of $\alpha$ wave and decrease of $\beta$ wave were observed but interestingly, Mid-$\beta$ and SMR of $\beta$ wave which mean the state of concentration were increased with statistically significant. According to these results, DCG-chim stimulation of Baihui($GV_{20}$) seems to lead to relaxation with antianxietic effect and improvement of concentration at the same time. Conclusions : It would be expected that the doctor can apply DCG-chim for treating anxiety, tension, symptom caused by stress and also can use it clinically for patients who have needlphopia or children as a non-invasive procedure. It is suggested that additional studies about the effect of DCG-chim on other acupuncture points and comparison study about the effect of DCG-chim with those of the finger-pressure treatment using other tool should be done in the future.
