Sensitivity and Speceficity of CMNAP test in diagnosis of CTS‌

Abstract

Abstract Background: Early diagnosis and treatment of CTS can prevent its progression. Objective: To determine the sensitivity and speceficity of CMNAP test in early diagnosis of CTS. Methods: This study was conducted on 60 normal hands and 76 CTS hands. Then the CMNAP of two groups were compared. Findings: The results indicated that CMNAP test with cut-off point of 2.2 showed sensitivity of 97.4% and speceficity of 93.3%. With cut-off point of 2.4, sensitivity increased to 98.3% but speceficity decreased to 85.5%. Conclusion: The CMNAP test with cut-off point of 2.4 or more and specificity of 98.3% is a reliable test for diagnosis of CTS patients.
