All rights reserved.Objective: The aim of this study was to determine whether a relationship exists between pain questionnaires, diabetic peripheral neuropathy, and the severity of electrophysiological findings. Methods: Patients with diabetes mellitus (DM) whose clinical signs and symptoms were found to be consistent with diabetic neuropathy were included in the present study in Ankara City Hospital Neurology Department between June 2020-January 2021. It was designed as a prospective cross-sectional study. Demographic characteristics, type and duration of DM, the onset of neuropathic complaints, systemic diseases, and DM treatments were noted. Blood tests were performed on all patients. Participants were administered the Douleur Neuropathique 4 Questions (DN4), Leeds Assessment of Neuropathic Symptoms and Signs (LANSS), and Numerical Rating Scale (NRS) questionnaires and an electrophysiological examination. Results: The study included 108 patients. A statistically significant correlation was found between the severity of electrophysiological findings and the age of patients, duration of diabetes, and treatment modality. Additionally, a statistically significant correlation was found between the severity of electrophysiological findings and blood urea nitrogen (BUN) levels and monocyte and platelet counts. According to the NRS, a significant relation was found between BUN values and the severity of pain experienced. The LANSS predicted the severity of electrophysiological findings at a significantly higher accuracy than other questionnaires. Conclusion: Questionnaires can detect diabetic neuropathy, which is mostly asymptomatic, before the onset of DM complications. The LANSS questionnaire reflects the electrophysiological findings severity.
