In each and every medical science of the world there is a method to examine the pulse of the patient. But the detail study of the pulse examination is found only in Ayurveda. No other science has deeper information about the Pulse examination. According to ayurveda 'Nadi' means Pulse and 'Parieksha' means exmaination but the term 'Nadi Parieksha' means a careful planned test carried out by the ayurvedic physician for diagnosis of disease.
In ayurveda pulse examination has become a synonym for 'Diagnosis'. In olden days when a pateint comes to an Ayurvedic Physician then without much delay he stretches his hand so that the physician examines his pulse and diagnoses his health problems. There have been some physicians who used to examine the pulse of the patient and were able to tell the etiology, symptoms and prognosis of the disease. From the historical point of view the knowledge of pulse examination is found during the medieval period (13 to 16th century).
Even thou there are 8 types of examination in ayurveda medical science such as Pulse, Urine, Faeces, Tounge, Voice, Touch, Eyes and Physical Shape. Pulse examination is basis of diagnosis in Ayurveda. Other examinations reveal the disorder at a particular region in a limited way but the examination of pulse is of fundamental importance in all disorders.
