Abstract:

Background: The physiological properties of nerve and muscle are usually modified due to pathophysiological changes resulting from many diseases like diabetes. Diabetic peripheral neuropathy (DPN), the common complication of diabetes, can be assessed electrophysiologically by nerve conduction studies (NCS).

Aim: A motor nerve conduction study of lower limb nerves in diabetics.

Material and Methods: The peroneal and tibial motor nerve conduction study was carried out on 40 male type 2 diabetic patients attending diabetic clinic in the department of medicine and 40 healthy male volunteers who served as control. Motor Distal latency (MDL), Amplitude(Amp) and Conduction Velocity(CV) were measured by using Computerized RMS EMG EP Mk II and surface electrodes.

Results: On comparing the parameters of NCS it was found that motor distal latency of both the nerves were higher in diabetics than controls with statistically significant difference. Results also show decreased amplitude and conduction velocities of nerves of both(right and left) sides in diabetics (statistically significant). All the parameters were found correlated with blood sugar levels in diabetics.

Keywords: Type 2 diabetes mellitus, peripheral neuropathy, peroneal nerve, tibial nerve , motor distal latency, conduction velocity.
