Based On Delphi Method Of Posterior Circulation Ischemic Vertigo Syndrome Distribution Regularity Of Research

Objective: We use questionnaires to experts to investigatie the syndrome distribution law of PCI,and to standardize themethodology and clinical diagnosis of vertigo TCM syndrome,and tolay the foundation for the syndrome differentiation of PCI in the model of the combination with disease-symptom-syndrome.Methods: Methods according to reference, questionnaires on TCM syndromes of vertigo were designed. Setting up Word document and Excel documents to summarize, Using the statistical analysis of frequency、 average、standard deviation to get an element source of quantum information. quantity Analytic hierarchy process、 average 、 standard deviation 、 frequency 、 a percentage of no importance is adopted to get the score. Then we will only preliminary evaluate the first round expert questionnaires.Filtering and supplementing the results of the first round expert questionnaires.improving before setting up the second one.Evaluating the second round expert questionnaires again.Experts tend to agree through two rounds of questionnaire, finally coming to the conclusion that the classification of syndromes and syndrome classification standards of PCI,and providing the basis of Clinical epidemiological investigation.Results:Coming to the conclusion that the classification of syndromes and syndrome classification standards of PCI through two rounds of questionnaire.There are two rounds of questionnaire in this study, SPSS 19.0 statistical analysis is used,,finally coming to the conclusion of the seven common TCM syndrome types: phlegm-turbiditydisturbing mind obstruction of collaterals by blood stasi deficiency of qi and blood, hyperactivity of liver-yang yin deficiency and yang hyperactivity deficiency of liver and kidney, kidney essence deficiency and sumarizing each syndrome classification characteristics.Conclusion: This study is an exploration and practice of TCM standardization, and offering help to syndrome classification standards of PCI,Providing research ideas and methods to the study of Other disease syndromes.
