Background: The reference values for nerve conduction velocity (NCV) for different nerves vary considerably in different population and region. There are factors that affect NCV such as age, gender, and temperature. The importance of motor nerve conduction study for the evaluation of the functional status of the patients median and tibial nerve for comparing the effect of therapeutic intervention with other diseases, which affect NCV is well-known in various studies.
Aims and Objectives: To establish the normal electrophysiological data, NCV variables, i.e., compound muscle action potential for the right median and right tibial nerve in normal healthy adults and to establish gender effect on NCV study variables in them.
Materials and Methods: All together 38 females and 80 male subjects, from first year MBBS, BDS, staff members of the Index Medical College Hospital and Research Center, Indore, Madhya Pradesh, India, between age group of 20-60 years were evaluated. All tests were done on JAVA RMS Aleron-201 series. Analysis was done using Statistical Package for Social Sciences 10.0 version.
Results: The mean ages of male were more than that of female with P value nonsignificant. The mean NCV of elbow-wrist and knee-ankle of males was more than that of female with P = 0.038 and 0.020, respectively, which was found to be highly significant.
Conclusion: The normative conduction parameter of commonly tested peripheral nerve in upper and lower limb could be used for the evaluation of peripheral nerve injury. Gender has a definite effect on NCS variables diagnostic conclusion could also be made from the nerve conduction study data.
