Comparison of Motor and Sensory Nerve Conduction in Upper Limb of Diabetics and Non Diabetics

Abstract

ABSTRACT:The physiological properties of nerve and muscle are usually modified due to patho physiological changes resulting from many diseases like diabetes. Impaired mobility and compromised dexterity leading to difficulties in daily life. Hand function in diabetes is affected mainly due to involvement of median nerve. Diabetic neuropathy the common complication of diabetes can be assessed electro physiologically by nerve conduction studies. Therefore, we analyzed both motor and sensory nerve conduction on upper limb nerves. Distal latency, Amplitude and conduction velocity were measured in both upper limbs by using RMS EMG EP II machine with surface and ring electrodes. It was found that distal latencies of both nerves were higher in diabetics than nondiabetics. The difference was statistically significant. Motor responses are more reduced below normal as compared with sensory responses in diabetics. Our study also revealed decreased amplitude and conduction velocity among cases. Our findings conclude that the nerve conduction studies are important in early detection of peripheral neuropathy so that prevention and management can be done in earliest possible way.

Electroneurological changes in peripheral nerves in patients post-COVID

“…Motor and sensory nerve conduction study was performed in an environment with temperature ranging between 21 and 25°C. Amplitude, conduction velocity as well as distal latency and F-wave latency were examined and compared with results in control group with the use of Mann–Whitney test ( 11 ). Sensory studies were performed antidromically.…”
