Abstract:
Pulse diagnosis has been taking an important part, together with the other diagnostic techniques, for determination of symptoms and treatment of patients with acupuncture. However, the traditional expression of pulse is complicated and subjective, so that the understanding of pulse diagnosis in termes of modern medicine is almost impossible. We tried to objectify the expression of pulse wave.
The pulse wave recorded from the six positions on radial artery according to the method described in Chinese Medicine through a force transducer. The recordings were processed for Fourier analysis utilizing a computer system. Characteristics of the pulse wave can be expressed quantitatively as a form of power spectrum of its components. The preliminary results of this study was reported at the 31th annual meeting of the Japan Society of Acupuncture. This time, we report the analysis on the basic pulse waves which have been recognized as negative-positive and imaginaryreal pulses.
Method
The subjects were normal volunteers of 36 males and 17. females. A force tranducer (Nihon Kohden TF-11S) Equipped with 0.52cm2 of sensitive area was placed on the radial artery under the pressure ranging from 20 to 550gr. The pulse wave thus recorded was led into the electronic computer (HITAC-20) to obtain the power spectrum of the frequencies.
Results
It was found that characteristics of the six kinds of pulse waves, i. e., floating-sunken, smooth-leap and slow-fast types, can be represented quantitatively in terms of frequency histogram. Further, a possibility to express so called "complex pulse" in Chinese Medicine by this method is suggested.
