Abstract This study aimed to investigate the carpal tunnel syndrome (CTS) in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA), compare the electrophysiological and ultrasonographic findings and evaluate related variables. Cut-off value of median nerve cross-sectional area (MCSA) was determined for the diagnosis of CTS. 70 RA patients, 39 PsA patients, a control group of 70 healty people were included in this study. Demographic characteristics, disease activity and functional status were recorded. Patients were referred for nerve conduction studies performed according to the American Academy of Neurology standards. Sonographic examination was carried on for MCSA evaluation. The mean age of patients was 51.87 ± 8.47, 50.61 ± 11.33, 49.75 ± 10.52 years and female ratio was 72.9%, 71.8%, 75.7% in RA, PsA and controls, respectively. Electrophysiologically, CTS frequency was found to be 13.2%, 15.4%, 3.5% in RA, PsA, control group, respectively, and a significant difference was found compared to the control group (p
