ABSTRACT
Introduction: Normative data of Nerve conduction study(NCS) are used to evaluate Nerve conduction study ofpatients presenting with signs and symptoms of peripheralnerve disease. The Nerve conduction velocity depends onage, gender, temperature and nerve diameter. The study wasdone to observe the effect of the cerebral dominance if anyon the motor nerve conduction velocity by recording nerveconduction velocity of both right and left sides in upper limb.Material and Methods: The nerve conduction study was doneon 100 medical students (50 male and 50 female) studying inAdesh Institute of Medical Science sand Research, Bathinda.Motor nerve conduction for Median nerve was done usingcomputerized software Octopus EMG/NCV/EP. Amplitude,duration and conduction velocity of Median Nerve weremeasured for both the upper limbs.Results: Motor nerve conduction velocity of Median Nervewas found to be greater in right limb (56.87 ± 3.6 m/s and57.5 ± 3.35 m/s) as compared to left limb (56.33 ± 3.53 m/sand 56.97 ± 3.48 m/s) in both male and female students but theresults were statistically non-significant (p>0.05). The latencyof median nerve conduction was less in females (2.65± 0.24ms and 2.75± 0.32 m/s) than in males (2.71± 0.27ms and2.78± 0.32 m/s) on both sides.Conclusion: Motor nerve conduction velocity was found tobe greater in right limb as compared to left limb in both malesand females Motor nerve conduction velocity was found to bemore in female students as compared to male students.
