In the present study, we found that in electro diagnostic studies of median, ulnar, peroneal and tibial nerves in DPN patients there was a significant increase in DML and FWML of all these motor nerves.
The interesting finding in our study was that the changes in DML and FWML were very highly significant (p<0.005) than those in MNCV and CMAP (p<0.01).
254 nerves showed increased FWML. These numbers are significantly higher than those for other parameters of motor nerve conduction.
Another finding in our study was that in 20.41% of the motor nerves studied FWML was increased while other motor conduction parameters like DML, MNCV and CMAP were normal.
In the present study, we found that FWML had maximum sensitivity and specificity in the patients of DPN (Table no.
