    Abstract:
    As the adipose tissue in epineurium is related to some extent to amount of body fat, it is possible that the amount of such fat may affect the nerve conduction. In this study, we have analyzed effect of Body Mass Index (BMI) on various parameters of nerve conduction study in one hundred seventy five healthy volunteers between ages of 18 and 66 years. BMI was determined and nerve conduction studies were performed prospectively in all the subjects using standardized techniques. Prolongation of distal motor latency (DML) was observed with increasing BMI except in motor Peroneal nerve. (In Median Nerve, P<005). F-Wave minimum latency was also found to be significantly prolonged in (P<0.05) in motor Tibial nerve. Higher BMI was found to be non-significantly associated with lower amplitude (both sensory and motor) except for peroneal nerve. Motor as well as sensory conduction velocity showed non-significant slowing along increasing BMI except sural and motor-sensory ulnar nerve in younger age group. This study demonstrated that various parameters of nerve conduction study can be affected by BMI. So, this biological factor has to be taken into consideration while interpreting nerve conduction studies.
