Objective: The aim of this study was to investigate the relationship between severity of impingement and clinical symptoms, physical findings and functionality in patients diagnosed with carpal tunnel syndrome (CTS). Material and Methods: Between April 2018- 2019, 74 (132 hand wrist) patients admitted to Medipol University Sefaköy Sum Hospital Physical Therapy and Rehabilitation and Neurology Outpatient Clinics with numbness and pain in hand and diagnosed as CTS by electroneuromyography (ENMG) were included. Demographic characteristics of the patients were questioned. Boston Symptom Severity Scale (BSSS) and visual analogue scale (VAS) were used to assess symptom severity, hand and finger grip strength measurements were performed to assess motor strength, and Duruöz Hand Scale (DHS) and Functional Status Scale (FSS) were used to determine functional status. Results: The mean age of the study group was 49.7±12.13 and 87.84% of them were female. 78.38% of the patients had bilateral and 17.57% had right side involvement. Stage 1, Stage 2, Stage 2, and Stage 3 CTS were detected in 46.2%, 37.1% and 16.7% of the ENMG examinations. When the ENMG results of the patients and the tests evaluating their clinical findings and functional status were compared, a significant correlation was found between the median nerve compression severity and mean VAS scores (p<0.001), there was no significant difference between mean BSSS scores, handfinger grip strength, mean DHS scores, and mean FSS scores in the groups. Conclusion: In our study, the relationship between the severity of median nerve compression and VAS alone showed that larger studies were needed. The contradictory results of the tests and scales evaluating the clinical findings once again reveal the necessity of electrophysiological studies to determine the staging and treatment decision.
