In spite of many studies on statistical model for pattern identifications (PIs), little attention has been paid to the complexity of pattern diagnosis processed by oriental physicians. The aim of this study is to develop a statistical diagnostic model which discriminates four PIs using multiple indicators in stroke. Clinical data were collected from 981 stroke patients and 516 data of which PIs were agreed by two independent physicians were included. Discriminant analysis was carried out using clinical indicators such as symptoms and signs which referred to pattern diagnosis, and applied to validation samples which contained all symptoms and signs manifested. Four Fischer's linear discriminant models were derived and their accuracy and prediction rates were 93.2% and 80.43%, respectively. It is important to consider the pattern diagnosis processed by oriental physicians in developing statistical model for PIs. The discriminant model developed in this study using multiple indicators is valid, and can be used in the clinical fields.

Objectives : Since there are complex associations between diseases/symptoms and acupoints, one-to-one correspondence may not be the proper approach. Pattern identification has been being used as a clinical framework to make treatment decisions by extracting and synthesizing clinical data including patients' signs and symptoms. In this article, we propose two different models explaining the relationships between diseases and acupoints based on the branch treatment [Zhibiaofa] and the root treatment [Zhibenfa]. Methods : We explained the relationships between diseases/symptoms and acupoints from the example data from our previous study on traditional acupuncture point selection patterns for pain control. Diseases include low back pain, migraine, irritable bowel syndrome, osteoarthritis, ankle sprain, carpal tunnel syndrome, and dysmenorrhea, and acupoints included LI4, BL23, BL25, SP6, BL60, TE5, and CV4. Results : The relationships between diseases/symptoms and acupoints can be explained directly based on the branch treatment, and also can be explained indirectly through pattern identification based on the root treatment. Pattern identifications included both meridian-based pattern identification based on the spatial information of diseases and visceral organ-based pattern identification based on the characteristics of diseases. Conclusions : In the East Asian traditional medicine, Korean medicine doctors choose the most appropriate acupoints based either on the diseases/symptoms (i.e., branch treatment) or on the results of pattern identifications (i.e., root treatment). It is necessary to understand the two different approaches to choose specific acupoints for the targeted diseases.

Objective: The purpose of this study was to develop a standard tool for pattern identification of radiation pneumonitis. Methods: Textbooks, published studies, and references with comments about patterns were reviewed. Through the Delphi method, we determined pattern identifications based on advice from a committee of experts composed of 13 Korean respiratory internal medicine professors. Results: Using the Delphi method, four pattern identifications were chosen: Qi Deficiency (氣虛), Yin Deficiency (陰虛), Heat Toxin (熱毒), and Phlegm Dampness (痰濕). The tool was developed in a question-and-answer format with 35 questions. Conclusions: A pattern identification tool that can discriminate the patterns of radiation pneumonitis for standardized diagnosis was developed through expert consultation. Further study of its validity and reliability is necessary.

Objectives: This study attempted to provide prescriptions that can be used according to the classification of menopausal disorders in order to increase the clinical utilization of CaPSPI (Diagnostic System for Climacteric and Postmenopausal Syndrome Pattern Identification). Methods: Delphi method survey was conducted for expert consensus on the Pattern Identification that could be used for each prescription by selecting frequent prescriptions based on the literature researched on the prescription of Korean medicine used for women with menopausal disorders. 11 experts participated in the questionnaire for posterity and 7 experts for sasang constitution. The survey was divided into the main prescription that can be mainly used for the patterns and the minor prescription that can be used although the suitability is somewhat low. Expert consensus was obtained through the second survey, and the pattern classification of prescriptions that were not confirmed here was confirmed through a face-to-face meeting. Results: There were 56 prescriptions mainly used for treatment for menopause, 45 for posterity and 11 for Sasang constitution. There were 69 identifications of 45 posterity prescriptions and 17 classifications of 11 Sasang constitutional prescriptions including major and minor patterns. By pattern identifications, the number of major/minor prescriptions was as follows. 肝鬱 14/5, 腎陰虛 8/2, 腎陽虛 4/1, 肝腎陰虛 2/7, 腎陰陽兩虛 3/1, 心腎不交 6/3, 心脾兩虛 15/2, 心火 7/6. Conclusions: In the future, by accumulating and analyzing the data on the diagnosis and treatment using CaPSPI, the clinical status of Korean medicine for menopausal disorders can be reviewed, and it can be used as the basis for the clinical practice guidelines for menopausal disorders. In addition, it is thought that analyzing the results of the diagnosis of pattern identifications and the prescription of Sasang constitution can be helpful in research on the posterity and Sasang constitution.

The goal of current study is to make a standard pattern identification for post stroke depression using a delphi method. Finally, ten experts of oriental medicine, especially of stroke or depression, participated in Dephi examination. At the first meeting, experts conducted free discussion and determined to use the previous published questionnaires of Deficiency-Excess identification and Cold-Heat identification. From the second round, experts participated in evaluating and correcting the questionnaire by email. New seven questions were added to the questionnaire of Deficiency-Excess identification through the second round. Finally, the standard pattern identification of Cold-Heat or Deficiency-Excess is composed 20 questions and 11 questions, respectively. These pattern identifications for post stroke depression will contribute to research and treatment of oriental medicine.

Objectives: This study was performed to evaluate the reliability and validity of the instrument of oriental medical evaluation for Hwa-byung. Methods: 97 participants diagnosed with Hwa-byung divided into 5 pattern identifications by the instrument on pattern identifications for Hwa-byung were tested by the instrument of oriental medical evaluation for Hwa-byung twice a week. Results: The intraclass correlation coefficient of the test-retest analysis of oriental medical evaluation for Hwa-byung had over moderate agreement. The intraclass correlation coefficient of test-retest analysis of evaluation index of symptoms had moderate agreement for the total symptoms, and fair agreement for the physical and mental symptoms. The validity analysis of the instrument represented a positive correlation in the pattern identification of stagnation of liver Gi, malfunction of gallbladder due to phlegm stagnation, and disharmony between heart and kidneys. Conclusions: The results showed that the reliability analysis of the instrument of oriental medical evaluation for Hwa-byung showed over moderate agreement, and validity analysis represented a positive correlation except for the pattern identification of flare-up of liver fire and deficiency of both Gi and blood.

Objectives : We performed a clinical study to investigate autonomic conditions in persistent allergic rhinitis depending on various pattern identifications and the availability of heart rate variability (HRV) as a pattern identification diagnostic tool. Methods : 32 patients with persistent allergic rhinitis were asked to interview with doctor of Korean Medicine and perform the four pattern questionnaires (Cold-Heat Pattern, Phlegm Pattern, Yin Deficiency pattern, bloodstasis pattern). Then, they were examined their autonomic conditions with heart rate variability test. Results : Patients were classified as three pattern groups (Lung-stomach heat, Lung qi deficiency cold, Lung-spleen qi deficiency) by doctor. In the Lung qi deficiency cold group, Total power of the HRV (TP) and the power of the low frequency component (LF) significantly higher than in the Lung-stomach heat or Lung-spleen qi deficiency group (P < 0.05). Also, Patients were classified as 8 pattern groups (Cold/Heat, Phlegm/Non-phlegm, Yin deficiency/Non-yin deficiency, Bloodstasis/Non-bloodstasis) by four pattern questionnaires. Only in the Yin deficiency group, the power of the low frequency component (LF) significantly lower than in the Non-yin deficiency group (P < 0.05). There were not any significant differences in the rest groups. Conclusions : The result may provide that HRV doesn't reflect well the differences in the various pattern groups, and the HRV's availability is low. Continuous studies are needed to develop the objective and standardized pattern identification diagnostic tool for allergic rhinitis.

Objectives: The aim of this study was to develop a standard instrument of pattern identification and evaluation for chemotherapy-induced peripheral neuropathy (CIPN).Methods: The advisory committee for this study was organized by 12 professors of traditional Korean medicine from the Korean Association of Traditional Oncology. The items and structure of the instrument were designed based on a review of previous publications. We revised the instrument in consultation with the advisory committee and received additional advice via email.Results: We divided the symptoms and signs of CIPN into four pattern identifications: wind arthralgia (風痺), cold arthralgia (寒痺), dampness arthralgia (濕痺), and arthralgia of the deficiency type (虛痺). We obtained the mean weights to reflect the standard deviations from each symptom of the four pattern identifications, which were scored on a 5-point scale by the advisor committee. After we obtained the answers to discrimination between variable symptoms (變症) and ordinary symptoms (素症) from the 12 experts, we gained the final weight from the combination of the ratio of pattern identification to the number of total answers of the advisory committee and the mean weight.Conclusions: The Instrument on Pattern Identification and Evaluation for CIPN was developed through a discussion between 12 experts. There was a limitation that the validity and reliability of this instrument have not been proven. However, the significance of this study was that it is the first Instrument on Pattern Identification and Evaluation aimed at assessing CIPN in traditional Korean medicine.

Objectives To evaluate the effectiveness of allergic rhinitis treatment, and to set the ground in clinical studies, adequate outcome measures must be established. Thus, this study was designed to develop useful criteria based on those that have been suggested, and those that we are using today. Methods To assess outcome measures used in allergic rhinitis in Korean medicine, related articles found in Korea Traditional Knowledge Portal from 2000-2015 were evaluated. Then pattern identification and outcome measures were reviewed in each study. Results Among 27 studies, we have found 24 studies used subjective symptoms as outcome measures, 9 studies used quality of life, and most of allergic rhinitis were caused by Spleen-Gi deficiency. Conclusions It is necessary to develop outcome measures that directly reflect pattern identifications in Korean medicine, and those measures need to be further evaluated for their applicability, validity and sensitivity.

Objectives: The aim of this study was to analyze the correlation between patterns determined by pattern identification of functional dyspepsia (FD) and tongue features, including tongue coating and tooth marks, in FD patients. Methods: We reviewed the clinical records of 68 FD patients who visited the Department of Digestive Diseases of Kyung Hee University Korean Medicine Hospital from September 1, 2020 to August 31, 2021. The subjects were evaluated with a computerized tongue image acquisition system (CTIS) and by pattern identification of FD. Measurement included the percentage of tongue coating, tooth mark levels, and pattern scores. Results: Statistically significant negative correlations were noted between the scores of the pattern of 'spleen and stomach deficiency and cold' (SSDC) and the percentage of tongue coating in whole, center, and root of the tongue body. However, no other patterns were correlated with any parameter measured by CTIS. No significant difference was noted in the percentage of tongue coating and the tooth mark level between the patterns. Conclusions: This study demonstrated that the pattern of SSDC was significantly associated with the percentage of tongue coating. We suggest that the percentage of tongue coating could be a useful indicator for identifying the degree of patterning of SSDC in patients with FD.
