Analysis of Tridosha in various physiological conditions

Ayurveda is one of the oldest literature which deals with the nature, scope and purpose of life. In the ancient times, pulse diagnosis using the signals obtained from the three precise locations on the wrist at the radial artery, viz. vata, pitta and kapha, played an important role in the Traditional Chinese Medicine and Ayurveda. The Nadi Vidwans using their experience and skill feel this signal on the patient's wrist. Any change in the nature of signal felt is a means of identifying any kind of imbalance in Doshas. In this paper, we have analyzed Variation in Tridosha during fever, before and after meal, epileptic jerks, and recovery phase of typhoid. An automated Instrumentation system is implemented to mimic the Nadi Vidwan's method. We have acquired the pulse signals using a suitable pressure sensor and processed in MATLAB. The imbalances of radial arterial signal in various abnormalities were observed. Graphical User Interface has been developed using MATLAB for displaying results.
