Effect of acupuncture at Tsu San Li (St-36) was examined by investigating the pulse variation of the radial artery. Our results indicated that acupuncture at Tsu San Li has a specific effect on the Fourier components of the pulse. The harmonic proportions were redistributed (C2, C4 decreased, C5, C6, C8 and C9 increased), and the phase angle of the 5th and 8th harmonic waves were decreased (propagating faster). This specific frequency effect was not found when acupuncture needle was applied on a non-acupuncture point. These results can be explained by the resonance theory, which provides a scientific explanation of the acupuncture effect from the hemodynamic view point.
通过研究桡动脉的脉搏变化来考察针刺足三里（St-36）的效果。我们的结果表明，针刺足三里对脉搏的傅里叶分量有特定作用。谐波比例发生了重新分布（C2、C4降低，C5、C6、C8和C9升高），并且第5和第8谐波的相位角减小（传播更快）。当将针刺入非穴位时未发现这种特定的频率效应。这些结果可以用共振理论来解释，该理论从血液动力学角度为针刺效应提供了科学解释。
