Assessment of Accuracy of the Toronto Clinical Neuropathy Scoring System and Vibration Perception Threshold in Diagnosing Diabetic Peripheral Neuropathy in Type 2 Diabetes Mellitus Patients

Diabetic peripheral neuropathy is a common and serious complication of type 2 diabetes mellitus, often leading to significant morbidity including foot ulcers and amputations. While nerve conduction studies are considered the gold standard for diagnosing DPN, they are expensive, time-consuming, and not always readily available in all clinical settings. The Toronto Clinical Neuropathy Scoring System and Vibration Perception Threshold are simpler, less expensive alternatives that could potentially be used for screening and diagnosis. However, their diagnostic accuracy compared to NCS in detecting DPN has not been thoroughly established. This study aims to evaluate the effectiveness of TCNS and VPT compared to NCS, potentially providing clinicians with more accessible tools for early detection and management of DPN. The results could lead to improved screening practices, earlier interventions, and better outcomes for patients with type 2 diabetes mellitus.
