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.
