The floating and the sunken describe the depth of a pulse, and can be quantified by shu, the unit of weight used during the Warring States period (403-221BC) of ancient China, with floating corresponding to three shu and sunken nine shu. The rapid and the slow describe the rate of a pulse, and can be quantified by the number of beats per breath.
A few of the descriptions, such as the rapid, the slow, the floating, and the sunken, are quantitative. For instance, the slippery is compared to “beads rolling” and the string-like is like pressing the string of a musical instrument. They are floating, sunken, slow, rapid, surging, fine, vacuous, replete, long, short, slippery, rough, string-like, tight, soggy, moderate, faint, weak, dissipated, hollow, drumskin, firm, hidden, stirred, intermittent, bound, skipping, and racing.ĭescriptions of pulse conditions in Chinese medical texts are mostly qualitative, and are often illustrated by similes and poems. The 28 pulse conditions most commonly used in clinical practice come from Bin Hu Mai Xue and Zhen Jia Zhen Gyan. Mai Jing documents 24 types which are floating, sunken, hollow, large, small, skipping, tight, rapid, stirred, slippery, weak, string-like, faint, soft, dissipated, moderate, slow, bound, drumskin, replete, intermittent, vacuous, rough and hidden. large, small, long, short, slippery, rough, sunken, slow, rapid, strong, tough, soft, moderate, hurried, vacuous, replete, scattered, intermittent, fine, and weak. Description of pulse condition in ancient Chinese medical texts The last section highlights limitations of current studies and recommendations are suggested accordingly.Ģ.1. Section four presents a tcm pulse diagnostic framework proposed by the author in 2010 to illustrate the interrelationship of pulse conditions and arterial pulse. Statistical approaches to quantify tcm pulse diagnosis are discussed. The first three sections discuss and analyze qualification and quantification of tcm pulse diagnosis in ancient and recent literatures. The review is divided into five sections. Highlight future direction of tcm pulse diagnosis quantification.
The aim of this review is to provide readers with a complete picture of current progression of tcm pulse quantification.Īfter reading this chapter, readers should be able toĪcquire up-to-date scientific evidence on tcm pulse diagnosis quantification Īnalyze strengths and weaknesses of current studies in terms of methodologies and statistical approaches and Much research work has been published since 1950s’ to quantify tcm pulse diagnosis which aims at providing scientific base to tcm pulse diagnosis and so substantiating its clinical value. In view of the increasing popularity of tcm world wide, tcm pulse diagnosis has received much attention from the public concerning its scientific and clinical values.
