Introduction: Normal nerve conduction velocity of radial nerve is essential for differential diagnosis of various type of radial neuropathies, C7 radiculopathy and nerve lesion. Aim: To study normal motor and sensory nerve conduction velocity of radial nerve in young adult medical students. Materials and Methods: Fifty medical students of either sex from first year, aged between 17- 20 year, were recruited for this nerve conduction study of radial nerve using surface electrode. Motor Nerve Conduction Velocity (MNCV) and Sensory Nerve Conduction Velocity (SNCV) of radial nerve of both hand were taken out and analysed for statistical significance and standard deviation. Results: The mean Motor Latency (ML) in right and left hand were 8.11 msec and 8.01msec respectively, Amplitude (A) 9.08mv and 8.65mv respectively and MNCV was 66.81m/sec and 67.05m/sec respectively. The SNCV were 51.41 m/sec and 51.48m/sec in the right and left hand respectively. Conclusion: The normative value of motor and sensory NCV of radial nerve in male and female young medical students were established. The data were within the favourable range as compared with the existing data from other researchers for radial nerve. There were no difference statistically found in the radial nerve motor and sensory NCV of right and left hand of either sex.
