Objective: Increasing incidence of diabetic polyneuropathy motivated to conduct this observational study to estimate prevalence of the disease specially Patna city in eastern India.

Material & Method: The present study was conducted on 720 type 2 diabetic subjects (580 male and 141 female) in the age group of 40 to 70 years. Vibratory perception threshold (VPT) was measured by Diabetic Neuropathy analyser which measures vibratory sensation quantitatively.

Result: Mean risk of Right foot VPT and Left foot VPT was considerably high in significant number of patients, which indicate the periodic check-up of diabetic neuropathy by conducting VPT in all groups of T2DM patients in daily clinical practice. More than 50% patients were at mild risk and 33% patients are at sever risk of diabetic neuropathy. Which indicates that despite in small no of patients and small tertiary set up, the statistical analysis indicate towards increasing prevalence of diabetic polyneuropathy among the patients od Patna city. 

Conclusion: From this study we can conclude that all cases of diabetic patients irrespective of clinical symptoms of neuropathy should be advised to undergo VPT on regular intervals as a part of routine diabetic check-up which can help in the early diagnosis of neuropathy & planning of future therapy to prevent progression of disease.
