Background:
The Carpal Tunnel Syndrome is one of the most common peripheral neuropathy. The diagnosis could be made by taking the medical history from a patient or by physical examination or by performing electroneurography. The aims of the study were (1) to translate and adaptate the Polish version of the Six-Item Carpal Tunnel Syndrome Symptoms Scale (CTS-6 SS) and (2) to analyse the associations between different Patients-Reported Outcome Measures and nerve conduction studies (NCS).
Methods:
One-hundred and fifty patients consistent with inclusion criteria filled the CTS-6 SS, Boston Carpal Tunnel Questionnaire (BCTQ), Disabilities of the Arm, Shoulder and the Hand (DASH) and Michigan Hand Outcomes Questionnaire (MHQ) during their first visit to the clinic. Then, they had the NCS done. After two weeks, 99 patients filled the CTS-6 SS for the second time.
Results:
The Polish version of CTS-6 SS revealed good psychometric properties: high values of internal consistency, test-retest reliability and validity. The construct validity showed strong correlation with BCTQ - R = 0.87 (p < 0.05) for Symptoms Severity Scale (SSS) and R = 0.64 (p < 0.05) Functional Status Scale (FSS). Additionally CTS-6 SS has at least moderate correlation with DASH R = 0.53 (p < 0.05).
Conclusions:
The Polish version of translated scale was adapted and used together with NCS complete the overall picture of patients suffering from CTS.
Study Design:
Prospective study.
