A Hospital-Based Retrospective Study of the Effect of Age and Gender on Median Nerve Conduction Study
Demonstrator, Department of Physiology, Gauhati Medical College, Guwahati-781032.
Nerve conduction study (NCS) provides an objective and quantitative measure of nerve function. A number of physiological variables, including age and gender, are known to affect the results of NCS. The present study investigated the effect of age and gender on motor and sensory parameters of NCS of Median nerve, including F-wave study. Study of the NCS records of 49 patients revealed higher compound motor action potential (CMAP) amplitude and longer F-wave latency in males whereas females had higher sensory nerve action potential (SNAP) amplitude. Further, with increasing age, latencies became longer, amplitudes became smaller and conduction velocities became slower. Therefore, age and gender of a person should be taken into consideration while interpreting his/her NCS results.
