OBJECTIVE: Peripheral neuropathy is a common complication of diabetes. The Prevalence of peripheral neuropathy among diabetic patients on the basis of loss of vibration sensation had been studied. METHODOLOGY: Detailed clinical history of each patient including age, gender, duration of diabetes, foot ulcer and biothesiometry was recorded in 91 diabetic patients between 20 to 80 age. It was observed that all patients under years of age (n=8) felt vibration below 15 volts (no risk zone); 77% (24 out of 31) of the patients in the age group 30- 39 years were in the no risk zone, and 23% (n=7) had mild peripheral neuropathy. Sixty per cent of the patients between 40 and 50 years (n=44) were in the no risk zone, while 32% (n=24) had mild peripheral neuropathy, 5% (n=4) had moderate neuropathy and 3% (n=2) have severe neuropathy. RESULTS: Amongst patients above 50 years of age, 31% (n=31) were no risk zoen, 34% (n=34) had mild peripheral neuropathy, 22% (n=20) had moderate peripheral neuropathy and 13% (n=13) had severe peripheral neuropathy. Of the patients with diabetes for less than 5 years, 58% had no neuropathy and only 3% had severe neuropathy. Of the patients with diabetes for 5 to 15 years, 50% had no neuropathy, 30% had mild and 10% had severe peripheral neuropathy. When patients with diabetes for over 15 years were studied only 6% had no neuropathy and 19% had severe peripheral neuropathy. CONCLUSION: The study reestablishes that the severity of peripheral neuropathy increases with age and vibration perception decreases progressively with increased duration of diabetes. Vibration perception threshold testing helps to identify the high risk the high subjects who require special counseling and education to protect their feet.
