Abstract
The pulse spectrum of electrical acupuncture at Tsu-san-li (St-36) was examined through Fourier’s analysis. Based on evidence-based medicine, we recorded the relationship between cyclic electric stimulation and radial pulse spectrum. We aimed to research the mechanism of acupuncture and provided one scientific way for chinese medicine research. 32 healthy subjects with 24 females and 8 males, aged between 20-32 were involved in this experiment. Each subject was asked to sit down and rest for 10 min, left radial artery pressure pulse was recorded with a pressure transducer. Blood pressure and heart rate were also recorded. Needle (size 30, 1.5 inch) was inserted into left Tsu-san-li (St-36) and was electric stimulated with machine for 15 min. The frequency was equal to heart rate and the intensity was tuned to the tolerant level for each subject. Radial pressure, blood pressure and heart rate were recorded after stimulation and rest for 10min later.
The harmonic proportions of 3rd (C3) and 6th (C6) harmonic waves were increased significantly (p<0.05) 10min after electrical acupuncture. The proportion of harmonic wave to total harmonic waves has no significant change neither immediately after electric acupuncture nor 10min after electrical acupuncture.
The study solidified the organ coupling resonance theory, which successfully explaint frequency specific effects. Electrical acupuncture had similar effect of simple acupuncture. It could redistribute internal organ energy and prove abdominal treatment of Tsu-san-li via increase of C3 (spleen ) and C6 (gallbladder ).
