There are various methods for diagnosing carpal tunnel syndrome, all of which are based on clinical trials; Clinical trials are in most cases capable of accurate diagnosis; However, many physicians use complementary tests such as electrodiagnosis to diagnose this syndrome; Therefore, the aim of this study was to compare clinical tests against electrodiagnosis to diagnose carpal tunnel syndrome.The present study was a cross-sectional study that was performed during ۲۰۲۰ on ۴۵ patients with carpal tunnel syndrome and ۳۳ healthy individuals referred to the orthopedic clinic of Imam Reza Hospital who were included in the study by random sampling method; Phalen’s, Durkan’s compression and electrodiagnosis tests were used for diagnosis and finally the predictive value of phalanx, compression and electrodiagnosis tests were evaluated by ANOVA statistical test.The difference between the mean latency of sensory nerve action potential between positive and negative phalanx groups was significant (P <۰.۰۰۱). Which differed significantly (P <۰.۰۰۱). Carpal compression test has more features, sensitivity, negative and positive predictive value than Fallen test. These results indicate that the compression test is more sensitive and more accurate in diagnosing patients with carpal tunnel syndrome.
