This study aimed to examine the possibility of data from pulse diagnosis device to be used for diagnosis of Sasang constitution. Systematic searches of 5 major Korean medical database were conducted for articles published up to May 2012. Searching key word was "Sasang" or "Constitution". Studies dealt with correlation between Sasang constitution and the pulse wave data from pulse diagnosis machine were included. Totally 2886 studies are searched and 3 studies are added from references of evaluated articles. Among them, 12 studies were met our inclusion criteria (2 Xishu Mac, 2 Self-made pulse diagnosis machine, 8 3D-Mac). Three of the eight 3D-Mac studies intended to develop a formula of constitutional differential diagnosis, 2 studies compared variables by Sasang constitution in healthy group and 3 studies compared variables by Sasang constitution in healthy group and special disease group. They all reported some significant variables, however results are not consistent between studies. The accuracy of the formula of constitutional differential diagnosis using 3D-Mac pulse diagnosis devices is 46.0% by now. Improvements in measuring pulse are required to achieve more accurate result and be used for diagnosis of Sasang constitution. Compensating B.M.I. among Sasang constitutional groups and separating constitutional pulse factors from acquired characteristics are also needed in further study.

In this paper, we implemented a computerized pulse diagnosis system for the developement of pulse diagnosis algorithms and the generalization of the pulse diagnosis. The system consists of the hardware and software. The hardware detects pulse waves and inputs the waves into the computer system, while the software not only manages and analyzes the input pulse wave data but also privides the database. In order to clinically test the developed pulse diagnosis system, we applied the carotid-radial pulse diagnosis algorithm to the system. As the results, it is found that the genralizatio of the pulse diagnosis is possible.

Pulse is one of the basic diagnostic information of TKM(Traditional Korean Medicine). To quantify and standardize pulse diagnosis, we had collected an amount of clinical data from May 2005 by using newly developed pulse analyzer. But there were many noises in pulse wave according to measuring method, environment, operator and condition of patient. So some data can’t be included for analyzing diagnosis. To reduce noises from measuring pulse and to collect reliable pulse wave data, we made the process map of measuring method and applied six sigma project. With this we can improved the method of measuring pulse wave in collecting clinical data. The project follows a disciplined process of five macro phases: define, measure, analyze, improve and control (DMAIC). A process map and C-E diagram are used to identify process input and output variables. The major input variables are selected by using C&E matrix, and process map is developed by analyzing input variables. And the optimum process conditions are going to be controled to avoid in increasing loss of collecting pulse wave data.

Pulse feeling is one of the most important diagnosis method in Oriental medicine. But it is not easy to make an objective and standardized diagnosis. In this study, we found how to quantify diagnosis. Specially dally the high practicality in clinic, we search some parameters especially well-related to floating and sinking pulse by statistic analysis. By extension, we find the pulse patterns of the floating and sinking pulse. We choose 15 subjects diagnosed as floating pulse and 15 subjects diagnosed as sinking pulse by oriental doctors. And their pulse signals were acquired by Pulse analyzer which has piezoresistive pressure sensor. For the quantification of the floating and sinking pulse, at first, we examined the parameters which were highly correlated with oriental doctor's diagnosis. And then we derived pulse patterns of the floating-sinking pulse from preprocessed signal and its ensemble average. We also looked trend variation (PH-Curve) between contact and pulse pressure. As a result, statistically there is the biggest difference between contact pressure, the maximum pulse pressure, diastolic area (Ad) and floating and sinking data. Through the PH-Curve, which represented the relationship between contact and pulse pressure, we could divide the floating and sinking pulse clearly. As a basic research of pulse diagnosis algorithm, we can contribute to select essential parameters in diagnosis algorithm And using these diagnosis method, we expect to find typical pulse patterns and some useful parameters about other pulses like slow/rapid, large/fine pulse and so on. We hope that this study will contribute pulse objectification.

The demand of research for the development of pulse meter and analyzer by the examination questionnaire made from repeated preliminary investigations. Which was presented in the exhibition KIMES 2008, it's has been proved to be practical. 159 people(oriental medical doctor) sent in the question papers and selected the double answers in the relevant question. At the time of the development of the pulse meter and analyzer, we put the investigation for oriental medical doctor's demands in practice and found the following results. The development of the pulse analyzer is getting more important for modernization of oriental medicine. The purpose of this study was to find out the research needs for the pulse analyzer considering the practical use in the oriental medical clinics. A survey was conducted at the KIMES 2008 exhibition with a set of questionnaires. We collected the data from 159 oriental medical doctors who attended the exhibition, and we found following results. The more oriental doctors did not think the diagnostic devices were important in their clinical practices. Most responders preferred to use the Chon-Kwan-Cheok pulse diagnosis. To find out the mechanism of the pulse diagnosis and to standardize it, the clinical data base containing the results of the pulse diagnosis and the patten discrimination of each patient should be established. In conclusion, the researches on the standardization of Chon-Kwan-Chuk pulse diagnosis including the measurement techniques and the pulse-pattern correlations are very important for developing the pulse analyzer.

In this study, we search some parameters well-related to floating-sinking pulse by statistical analysis, because these pulses are frequently used in clinic. Pulse signals were acquired by 3D pulse analyzer and 30 subjects consist of 15 people diagnosed as floating pulse and 15 people diagnosed as sinking pulse by oriental doctors who have over 5 years clinical experience. Then, we made a representative beat template for each subject and, through a peak detection algorithm, we calculated several pulse parameters. To find the parameters related to floating-sinking pulse, we performed statistical testing with 17 parameters through the independence sampling, t-test. As a result, there is the biggest difference between pressure, the maximum pulse pressure, diastolic area(Ad) and float-sink data. (p < .05).
