Objectives : The purpose of this study is to find parameters to compare the effects of Sa-Am acupuncture with stomach-tonification (ST) and Sa-Am acupuncture with spleen-tonification (SP) on radial pulse. Methods : Forty healthy subjects participated in this study. Radial pulse was measured using 3 dimensional pulse imaging system (DMP-3000) before, right after, 30 minutes after, and 60 minutes after acupuncture. Results : 1. The parameters analysed in this study were changed in the same direction with different degrees by ST and SP. 2. In males, SP manipulation showed significantly increased pulse period and (T-T4)/T, and significantly decreased T1/T, T4/T, T4/(T-T4), and F1~F3 frequencies compared to ST. 3. In females, ST manipulation showed significantly increased (T-T4)/T, and significantly decreased F1~F3 frequencies compared to SP. Conclusions : The parameters analysed in this study may be used to differentiate the effects between ST and SP on radial pulse. These parameters are more strongly affected by SP than ST in males whereas more strongly affected by ST than SP in females.
