Association of deha prakriti with neurophysiological parameters with respect to Ulnar nerve in young and middle aged healthy volunteers-an observation Study

Introduction: Prakriti is a unique concept of Ayurveda which emphasises on the personalised treatment approach of individuals. Prakriti (body constitution) is of seven types depending on the permutation and combination of doshas attributes. Each Prakriti have their unique features and vary in anatomical features, metabolic rate, pace of activity, temperaments, habits. The vata dosha with chala guna(attribute) has fast movements (muscular, nervous), the pitta dosha with tikshna, ushna guna is responsible for cellular digestion and metabolism, the kapha dosha causing anabolic and synthetic functions represents the manda guna. The clinical significance of these guna can be co-related with the range of nerve conduction.1,2 This study aims to define scientific understanding of dosha gunas in specific prakriti and further document  the classical Ayurveda concepts in this contemporary era of research and technology.

Nerve Conduction is one of the novel areas which can be studied in prakriti types. Myelinated nerve fibres are wrapped by lipoprotein membranes of myelin are integrated with subsets of proteins specifically in each compartment to shape the physiological behaviour of these nerve fibres which is affected by genetics.3 For ex: a person with a Vata- Prakriti may have a predisposition to nervous system disorders, while a person with a Pitta- Prakriti may be more prone to inflammation-related issues that can affect nerve function. The normal values of NCV are 50-70 m/sec, the NCV of nerve may vary according to genetics. Nerve conduction studies assist in the evaluation of predisposition of neuromuscular diseases by providing a physiologic assessment of the peripheral nerve. Motor nerve conduction studies assess motor axons by selectively recording muscle responses to nerve stimulation. This study aims to find the association between deha prakriti type and neuro-physiological parameters  in ulnar nerve.
