Abstract
For many diseases, new methods and models for their prediction, diagnosis and analysis are sought. We apply mathematical models for the interaction of the internal and biologically active points of meridian structures and can thereby specify diseases for which reflex diagnostics and reflex therapy methods are the most effective; amongst these are diseases of the gastrointestinal tract. The use of fuzzy logic decision-making yields good results for the prediction and early diagnosis of such diseases, depending on the reaction energy of biologically active points (acupuncture points).
