Mycobacterium leprae causes leprosy and can impair peripheral nerves. If nerve function is damaged and is not treated immediately and effectively, it can cause disability. Hence, early detection of peripheral neuropathy is critical. Toronto Clinical Scoring System (TCSS) is a simple neuropathy assessment instrument for diabetic neuropathy, chemotherapy-induced peripheral neuropathy, and human immunodeficiency virus neuropathy. Therefore, TCSS is expected to be an alternative tool for diagnosing leprosy neuropathy. This study aims to determine the diagnostic value of TCSS in leprosy neuropathy. This is a cross-sectional observational study with 40 participants. The TCSS and Semmes–Weinstein Monofilament tests were used to assess neuropathy. The diagnostic analysis showed that the sensitivity was 85.7%, specificity was 84.2%, positive predictive value was 85.7%, negative predictive value was 84.2%, positive likelihood ratio (LR+) was 5.42, negative (LR-) was 0.17, accuracy was by 85%, and area under curve value of 93.2%. The optimal cut-off point score of TCSS is ≥6. It can be concluded that TCSS is an alternative diagnostic tool with a high accuracy value and can be used as a routine examination for the early detection of leprosy neuropathy.
