Normative data of median nerve conduction in the state of Haryana
Journal Title: Indian Journal of Neurosciences - Year 2018, Vol 4, Issue 1
Abstract
Introduction For evaluation of peripheral nerve function nerve conduction study NCS is done all over the world Nerve conduction study can be used in a dual way ie prognostic as well as the diagnostic tool As nerve conduction study is dependent on many factors such as age height weight temperature gender etc there is a great variation between standard normal values accepted in different parts of worldObjectives Till now we are using standard values adopted by western countries like USA Canada Europe etc as normative data for our population because it is not found in literature Hence this study was designed to find out normative data for population of Haryana on the basis of which we can draw a comparison between normative data of our region to the standard values adopted by western countriesMaterials and Methods This study was taken place in the electrophysiology laboratory of Post Graduate Institute of Medical Sciences Rohtak We have studied 330 median nerves Out of them 116 nerves were of females and 214 nerves were of males Patients with history of peripheral neuropathy neuromuscular disease diabetes mellitus alcoholism etc were excludedResults Out of the total 330 median nerves studied 163 were of left side and 167 were on right side Average age of study group was 3463 years height was 15824 centimeters and weight was 5702 kilograms Average latency of the group was 739 plusmn132 ms duration 1362 plusmn369 ms amplitude 948 plusmn522 mV with a conduction velocity of 5861 plusmn551 msConclusion Studies done earlier were lacking statistical power as sample sizes were small including either students or staff members alone Our study provides normative values of NCS of median nerve to be accepted as reference value in our electrophysiology lab as population from several places of State of Haryana was studied for median nerve conduction to make a large sample sizeKeywords Nerve conduction study Normative data Median nerve
