Abstract
Background: Upper Extremity Disorders (UEDs) are a common health problem, causing temporary and sometimes long-term work disability and implying considerable costs for employers and society. So, it is necessary to assess disability and symptoms in Egyptian patients with upper extremity disorders. Aim of Study: To examine the reliability and validity of the Arabic Shortened Version Disabilities of the Arm, Shoulder and Hand questionnaire (Arabic Q-DASH) in UEDs. Material and Methods: Sixty-two patients with UEDs completed the Arabic Q-DASH questionnaire at the beginning of study and after 3 days without any intervention between the baseline and second administration. Internal consistency was examined using Cronbach's alpha; test-retest reliability was measured using intra-class correlation coefficient (ICC). Results: Cronbach's alpha of the Arabic Q-DASH ques-tionnaire was high (Cronbach's alpha=0.88). Test-retest reli-ability was good (ICC: 0.84). Conclusions: The Arabic Q-DASH questionnaire is a reliable and valid upper extremity outcome measure for assessing patients with various upper extremity disorders, whose primary language is Arabic.
