Abstract
Background: Nerve conduction studies are important electrophysiological tests to assess functional status of peripheral nerves. Median nerve is susceptible to entrapment in carpal tunnel. Thus this study was proposed to prove body mass index (BMI) as a modifying factor of median nerve conduction.
Method: This was a prospective study conducted on 47 healthy male subjects. Subjects were distributed in three study groups i.e. Normal, Pre-obese and Obese according to BMI. Nerve conduction study was done to compare various parameters of CMAP (Compound Motor Action Potential) and SNAP (Sensory Nerve Action potential). Parameters taken for CMAP were distal motor latency (DML), conduction velocity (CV) and amplitude (Amp) where as for SNAP peak latency (PL), conduction velocity (CV) and amplitude (Amp).
Result: CMAP of right median nerve between various groups represented significant prolongation of DML (p = 0.000), slowing CV (p = 0.000) with increasing BMI. CMAP of left median nerve between various groups represented significant prolongation of DML (p = 0.000), slowing CV (p = 0.000) with increasing BMI. SNAP of right median nerve between various groups represented significant prolongation of PL (p = 0.000), slowing CV (p = 0.000) with increasing BMI. CMAP of left median nerve between various groups represented significant prolongation of PL (p = 0.000), slowing CV (p = 0.000) with increasing BMI.
Conclusion: This study opined that BMI has the role to affect median nerve conduction at carpal tunnel. Thus persons of higher BMI are more susceptible to develop Carpal tunnel syndrome.
