Nerve conduction study in healthy individuals

Abstract

Background: Nerve conduction studies (NCS) are electrodiagnostic tests which are used to evaluate the ability of the conduction of the motor and the sensory nerves. NCS tests are used in the diagnosis of polyneuropathies, mononeuropathies, radicular lesions, tunnel syndromes and nerve damages caused by trauma and compression. Objective: The objective of this study was to evaluate the normative data of nerve conduction study (NCS) parameters among healthy young adults and effect of gender on nerve conduction study parameters.. Materials and methods: This study was conducted in Kathmandu University School of Medical Science, Dhulikhel from January to November, 2015. The study was done in total 40 out of which 20 were males and 20 were females consenting healthy adults. The compound muscle action potential (CMAP) and sensory nerve action potential (SNAP) were recorded. Result: The mean age of participants was 19.50 1.56, height was 167.24 7.32, weight was 60.22 5.47 with mean BMI 20.12 3.24 . The motor nerve conduction duration is minimum in median nerve while maximum in radial nerve. Amplitude is higher in median nerve while lower in radial nerve. The motor nerve conduction duration is minimum in median nerve while maximum in radial nerve. Amplitude is higher in median nerve while lower in radial nerve. The sensory nerve conduction duration, amplitude and latency are more in median nerve than in ulnar nerve. Conclusion: Nerve conduction study variables are within the normal range compared to previous studies.
