Background and Aim: Electrical conduction of motor and sensory nerves of the human body is evaluated by Nerve Conduction Velocity, which is a part of electro-diagnostic procedures, which help in set up the type and character of the nerve and commonly used to evaluate function of nerve. Present study was performed with an aim to know the effect of Height and BMI on median motor nerve conduction velocity. Materials and Methods: A Descriptive Cross–Sectional was conducted in the Department of Physiology, Index Medical college Hospital and Research Centre, Indore. The study group included 55 female medical students with age 18 to 23 years in secretory phase of menstrual phase. Nerve conduction velocity was calculated by recording evoked electromyogram (EMG) by stimulating median nerve at elbow and at wrist with the help of EMG electrodes and isolated stimulator by using Power lab 8/30 series with dual Bioamplifier. Statistical analysis was done by using Karl Pearson Correlation coefficient. Results: There is quite negative correlation effect with height on motor nerve conduction velocity with “r” value -0.26, and results was found to be not statistically significant. There is slender negative correlation effect of BMI on conduction velocity with “r” value -0.17 which was also non-significant. Conclusion: Through escalating height and BMI, nerve conduction velocity is diminishes which was found to be not significant statistically. The above two biological factors be required to be taken into contemplation as understanding nerve conduction studies.
