Comparative Study of Nerve Conduction Velocity Studies in Type II Diabetes Mellitus with&Without Features of Clinical Peripheral Neuropathy

Aim of our study was to study& compare nerve conduction velocity (NCV) in the patients of Type II Diabetes Mellitus with& without clinical peripheral neuropathy. Study population included DM type II patients. They were evaluated for Clinical Peripheral Neuropathy with the help of Neuropathy Symptoms Score& Neuropathy Disability Score. On the basis of these scores they were divided into two Group A (CPN) - 50 Type II Diabetes Mellitus patients with features of Clinical Peripheral Neuropathy. Group B (WCPN) - 50 Type II Diabetes Mellitus patients without features of Clinical Peripheral Neuropathy. Then these Groups were subjected to Nerve Conduction Velocity Study. The most common symptom of neuropathy was Tingling, Numbness and most common sign was loss of Ankle Jerk. Distal symmetrical sensory neuropathy (DSSN) was major clinical type of neuropathy. In Group A patients, NCV study was abnormal in 90 % patients. In Group B patients, NCV study was abnormal in 60 % patients. Most common type of neuropathy observed in NCV study was Axonal Sensorimotor type.
