Nerve Conduction Study of Radial Nerve in Type2 Diabetes Mellitus Patients in The Age Group 30-65years

Nerve conduction study measures the speed of electrical impulse in a nerve.NCS represent the least variable and non invasive method for assessing neuropathy.This study will help to mark the difference between all the parameters of nerve conduction study with both motor and sensory radial nerve of type2 diabetes mellitus patients. Objectives: To evaluate latency,amplitude,velocity of radial nerve in type2 diabetes mellitus patients. The study intends to findout the effect of type2 diabetes on the radial nerve of the upper extrimities. Materials and method: The study include 574 subjects,both male and female within the age group 30-65 years ,informed written consent was taken from all the subjects.the subjects were divided into two groups 1 and 2.Group 1 subjects includes duration of diabetes less than equal to 5 years and group 2 subjects includes duration of diabetes more than 5 years. Anthropometric variables were recorded.Motor and sensory nerve conduction parameters of bilateral radial nerve were recorded by using a four channel RMS nerve conduction machine . Results: it was found that there was a significant (p˂0.05) for proximal motor latency of both right and left radial nerve with the duration of diabetes. There was a non significant change in distal latency (p˃0.05) among the diabetic duration less than equal to 5 years or more.There was a non significant change in the amplitude (p˃0.05) for both motor and sensory among the diabetes patients less than equal to 5 years and more than 5 years. Conclusion: We conclude that implementing early electrodiagnostic testing for assessment of peripheral neuropathy is best detected by taking particular note the velocity of the nerve conduction of radial nerve which is significantly more prone to fall below the average value for normal healthy individuals even in newly diagnosed diabetes mellitus
