A diagnostic system based on fuzzy logic for clinical examination of patients in ayurveda

Abstract

Ayurveda accentuate on ‘Personalized Treatment’ as it considers very individual different in terms of physical and mental traits. Hence Ayurvedic Physicians carry out Dashvidh Prakisha (Ten Fold Examination) of patients to assess various aspects of personality, temperament, health status of the patient. This examination will help the physicians to provide the personalized treatment and appropriate dose of medicine to the patients. The prime objective of this research is to develop a tool based on fuzzy logic to automate the clinical examination of patients. A fuzzy controller is designed which has all the input and output parameters acquired by rigorous consultation with Ayurvedic Physicians. A knowledge base constructed by mapping input parameters to an appropriate output parameter based on the expertise of Ayurvedic Physicians is fed into the fuzzy controller. Comparative study is applied for assessing the performance of the proposed system. Diagnosis carried out by the Ayurvedic Physicians and results generated by the system and are compared for 150 patients.
