Abstract

BACKGROUND
The Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) is one of the most widely used questionnaires for assessing functional ability of the patients with upper extremity diseases. Carpal tunnel syndrome (CTS) is the most common neuropathic disease in the upper extremities. The aim of this study was to verify the validity, reliability, and responsiveness of Korean version of QuickDASH questionnaire (K-QuickDASH) in the patients with CTS.
METHODS
In total, 83 subjects who underwent open carpal tunnel release (CTR) operation were selected. They fulfilled Korean version of Disabilities of the Arm, Shoulder and Hand questionnaire (K-DASH) and K-QuickDASH at two different time points: before and six months after the surgery. Both criterion-related and construct validities were evaluated using Pearson's correlation coefficient and factor analysis. Internal consistency was estimated using Cronbach's alpha, and test-retest reliability was assessed to verify the reliability of K-QuickDASH using intraclass correlation coefficient (ICC). The standardized response mean and the effect size were analyzed to confirm the responsiveness of the K-QuickDASH in CTS patients.
RESULTS
Significant positive correlation was found between K-QuickDASH and K-DASH. All the questionnaire items were categorized into three factors. Acceptable internal consistency was confirmed in three categories of K-QuickDASH. A high test-retest reliability and responsiveness of K-QuickDASH were detected.
CONCLUSION
K-QuickDASH in Korean patients with CTS was confirmed to have high degree of validity and reliability, and responsiveness after CTR. Therefore, the K-QuickDASH would be a good evaluation tool for evaluating clinical symptoms and determination of treatment outcomes in the patients with CTS.
