Objectives: Ryodoraku diagnosis has been used frequently since Nakatani invented it in 1950. There are many papers about how to use Ryodoraku diagnosis in many diseases, but there are no studies about the repeatability and reproducibility of the Ryodoraku score. The aim of this study was to investigate the repeatability and reproducibility of the Ryodoraku score. Materials and Methods: There were four examiners who trained for more than a month, and the number of subjects was twenty. Each of the examiners made Ryodoraku diagnosis for ten subjects three times. We analyzed data by SPSS, used Friedman test, Wilcoxon signer rank test and Spearman correlation test. Results: 1. There was no significant difference between first, second, and third Ryodoraku score by Friedman test in examiners A, B, C, and D, so there was repeatability. 2. There was very high correlation on first, second, third Ryodoraku score by Spearman correlation test in examiners A, B, C, and 0, so there was repeatability. 3. There was high ICC among Ryodoraku score by examiners B, C, and D, so there was reproducibility. 4. After observing four examiners' Ryodoraku diagnoses, we could see the discord of measure points, the amount of hydration before examination, the amount of pressure, examination time, or positions of subjects diagnosed with Ryodoraku incorrectly. Conclusion: There is repeatability and reproducibility of Ryodoraku diagnosis. However, it is still important that one examiner carry out the diagnosis if possible. When there are two or more examiners, they should train extensively and follow manuals.

Objectives : The aim of the study was to investigate the characteristics of Ryodoraku score according to dyspepsia in diagnosed as Soeumin by 'portable Ryodoraku device'. Methods : Using Mann-Whitney U test, we divided 34 'Soeumin' patients into two group(normal and with chronic dyspepsia) and analyzed Ryodoraku score, especially in 'the spleen meridian' and 'the stomach meridian' which is belived to be related with dyspepsia. Soeumin subjects are classified by 'Sasang constitutional program' in portable Ryodoraku device. All of them complete the questionnaire regarding their Digestive conditions. 'short from leeds dyspepsia questionnaire(SF-LDQ)' made by rome III diagnostic is chosed as questionnaire. Results: 1. We found the RS measured from a group of people who has chronic dyspepsia was significantly greater than that from control group. 2. Regarding the effect of 'dyspepsia' in Ryodoraku, the mean score of the F6(stomach meridian) in the chronic dyspepsia group was significantly higher than that in the control group. 3. The mean score of the F6(stomach meridian RS) in the chronic dyspepsia group was not significantly higher than that in the control group. 4. In cases where people has chronic dyspepsia, the difference between RS measured in the right-side of a body and that in the left-side of a body was mostly greater than 40, whereas the case of difference that is less than 2 was rare. Conclusions : Portable Ryodoraku device might be used to classify enforce 'Sasang constitution', and also it might be used to analyze 'Ryodoraku data' based on characteristic clinical symptoms of four constitution diagnosis alone.

Objectives The purpose of this study is to investigate the characteristics of Ryodoraku Score in the children who visited department of pediatrics, hospital of Korean medicine with allergic rhinitis as the chief complaint. Methods Subjects were 80 children with allergic rhinitis. We calculated the average Ryodoraku Score (RS, ${\mu}A$), and compared the average of each meridian system. And we classified the children by several groups (depending on age, additional allergic disease), and accomplished a comparative analysis. Results 1. The average of Ryodoraku Score in 80 children was $76.36{\pm}22.72$. 2. The figure of H3 (心), H5 (三焦), F1 (脾), F2 (肝), F3 (腎), F4 (膀胱), F5 (三焦), F6 (胃) had significant statistical differences compared to the total average. 3. Comparing the group having only allergic rhinitis to group having allergic rhinitis and other allergic disease, showed significant statistical difference in H2 (心包), H3 (心). 4. Analyzed by age, there's a significant statistical difference in F1 (脾), F4 (膀胱). Conclusion We found that H5 (三焦), F1 (脾), F4 (膀胱) showed significant statistical difference in Ryodoraku Score, and F1 (脾) had the highest relevance. The research indicate meaningful difference depending on age, additional allergic disease.

Objectives : The aim of this study was to investigate the characteristic of ryodoraku in the chronic low back pain patients who visited department of oriental rehabilitation medicine. Methods : Subjects were 32 patients who visited department of oriental rehabilitation medicine(<60 years old). The low back pain patients were measured points of twelve meridians by ryodoraku diagnosis and checked the duration of low back pain. We compared the mean ryodoraku and the percentage of each points beyond the physiological range. Results : The score of H1(LU9), H2(PC7), H3(HT7), H5(TE4) and F5(GB40) had statistical differences compared with mean ryodoraku. And the correlation between duration of pain and mean ryodoraku showed statistically significant negative correlation(r=-0.353). Conclusions : These results suggest that ryodoraku maybe used to evaluate chronic low back pain patients.

Objectives : The aim of the study is to investigate the correlation of Ryodoraku score and four constitution in the patients with chronic low back pain. Methods : Using Pearson's correlation test, we divided 79 patients into two groups(normal and chronic low back pain group) and analyzed the correlation between Ryodoraku score and major constitution rate of four constitution. Results : 1. Ryodoraku score in the chronic low back pain group was mostly found to be below 40 ${\mu}A$, regardless of constitution. 2. There was negative correlation on F2 in lesser Yin person of chronic low back pain group, and there was positive correlation on H4 H5 F2 F4 and F5 in greater Yin person of chronic low back pain group. 3. There was negative correlation on H1 and H6 in lesser Yang person of normal group. 4. There was negative correlation on H6 in lesser Yang person of total group including normal and chronic low back pain group. Conclusion : These results suggest that roydoraku should be correlated to four constitutional diagnosis in part and available to increase accuracy of four constitutional or Ryodoraku diagnosis.

Objectives : The purpose of this study is to investigate the repeatability and reproducibility of the Ryodoraku acupuncture device. For such device to be accepted as a good apparatus for clinical diagnosis, the score it provides should be stable no matter who measure it or when it is measured, assuming all other conditions equal. Materials and Methods : Three oriental medical doctors who were well trained and fully aware of the usage of the Ryodoraku acupuncture device examined ten randomly selected patients three times. Each doctor measured the Ryodoraku scores three times from each of the 10 selected patients. Three doctors were involved in this experiment to investigate the reproducibility and each of them measured the Ryodoraku scores three times from each patient to investigate the repeatability. Data was analyzed with Friedman test, Spearman correlation test, and intra-class correlation coefficient(ICC) in SPSS ver. 18. Results : 1. The Friedman test showed that there is no statistically significant difference between the 1st, 2nd and 3rd Ryodoraku scores measured by the same examiner. It indicates that the Ryodoraku acupuncture device provides the repeatability. 2. Spearman correlation test confirmed the results obtained by the Fiedman test by showing that there exists a strong positive correlation between the three Ryodoraku scores measured by the same examiner. 3. A very high ICC among the three examiner assured that the Ryodoraku acupuncture device achieves the reproducibility. Conclusions : The Ryodoraku acupuncture device achieves the repeatability and reproducibility. However, we still recommend that a doctor trained to a certain level use the Device to carry out the diagnosis. Also, to improve the device in terms of Reproducibility even more, it should be considered to provide a manual for the exact usage.
