COMPARISON OF SENSORY NERVE CONDUCTION IN UPPER LIMB AND LOWER LIMB IN ASYMPTOMATIC DIABETICS AND NORMAL VOLUNTEERS

Background & objective: Study was undertaken to evaluate the magnitude of effect of DM on nerve conduction in upper limb and lower limb in diabetic individuals and to compare the results with normal healthy volunteers. Method: The study was carried out at NHL medical college in 5o diabetic and 50 normal volunteers. NCV was measured by EMGNCV recording machine, Neuroperfect plus of Medicaid systems. Result: Amp & CV in upper limb nerve i.e. median nerve in diabetics was 30.1±8.3µv, CV 52.1±3.8 m/s while in lower limb nerve i.e. sural nerve, it was 10.3±4 µv and 46.8±3.5 m/s. the value for amplitude and conduction in healthy volunteers in upper limb was 36.8±5.4 µv and 58.7±2.4 m/s and in lower limb the value for the same were 15.8±4.0 µv and 50.6±1.9 m/s. The results were analyzed using unpaired t test and were found to be highly significant*. Conclusion: It was observed that in diabetes, nerves of the both the limbs are affected but the upper limb nerves are affected more. *P value – 0.00
