Purpose To study the peripheral neuropathy among type 2 diabetes mellitus patients by biothesiometer. Methods: This study was conducted at tertiary care hospital, in medicine out patient department (OPD) and ward with a sample size of 87. All patients having type 2 diabetes mellitus including males and females, who met both inclusion and the exclusion criteria were recruited into the study. Blood samples were collected to measure fasting blood sugar, post prandial blood sugar, glycated hemoglobin (HbA1c) to indicate the glycemic status of the subjects and lipid profile. The use of vibration perception threshold (VPT) testing has also been validated as a method of diagnosing diabetic peripheral neuropathy (DPN). Results: Out of 87 subjects, 68 subjects had peripheral neuropathy and 19 subjects did not have peripheral neuropathy on biothesiometer whereas according to nerve conduction velocity 79 subjects had peripheral neuropathy and 8 subjects did not have peripheral neuropathy. Conclusion: From the present study we recommend use of biothesiometer in patients with type 2 diabetes mellitus for early detection of peripheral neuropathy.
