Distal symmetrical polyneuropathy detected by vibration perception threshold among adults with and without diabetes attending a general outpatient clinic in Ilorin, Nigeria

The aim of this study is to compare the prevalence, severity, and symptoms of Distal Symmetrical Polyneuropathy (DSP) among adult patients with diabetes and those without diabetes in a primary care clinic. It was a cross-sectional comparative study involving 72 adults of between 40-60 years of age living with diabetes and 72 age-matched adults without diabetes. DSP was assessed with a biothesiometer device, and data analysis was performed using the SPSS Version 21 statistical software. The overall prevalence of neuropathy among the participants was 68.1% for those living with diabetes and 38.9% for the other group. Furthermore, 22.3% of the diabetes group had severe neuropathy compared with 8.3% of the other group. These differences were found to be statistically significant with p=0.001 (df = 2, X2 = 14.07). We reported higher prevalence and severity of DSP in those living with diabetes. We also found significant association between high VPT (≥25V) and presence of neuropathic symptoms thereby enhancing the use of the biothesiometer device in the diagnosis of adults with DSP in the primary care setting.
