Background: Nerve conduction study (NCS) is an important method to assess the integrity of peripheral nervous system. It helps in diagnosis, planning of treatment, and prognosis of diseases of peripheral nerves. NCS parameters are affected by several different physical factors like temperature, demography, and ethnicity. It can also be affected by age, gender, height, weight, BMI, etc. The present study was targeted at finding out the changes in median and ulnar nerve conduction related to demographic parameters. Methods: Seventy-five healthy subjects aged 40?70 years undertook NCS using standard protocol. It was a cross-sectional study conducted at Institute of Basic Medical Sciences, Khyber Medical University, Peshawar and Combined Military Hospital, Abbottabad. The NCS were performed on Nion Kohden Neuropack MI EP/EMG measuring system. Various physical and demographic factors, i.e., age height, weight BMI were correlated to NCS parameters using Pearson’s correlation. Results: A total of 75 people 32 (42.66%) females and 43 (57.33%) males were recruited for study after qualifying the inclusion criteria. A decline in all NCS parameters was observed with advancing age. Height affects sensory and motor latencies (negative correlation). Weight and BMI don’t have prominent effects on NCS parameters. Conclusion: The sensory NCS characteristics (amplitude, latency, and Nerve Conduction Velocity (NCV) and motor NCS parameters (amplitude and NCV) of the median and ulnar nerves significantly deteriorate with age. Except for ulnar sensory amplitude and latency, there was no discernible variation in NCS characteristics between males and females.
