Abstract
The purpose of the study was to test the responsiveness of the Arabic-modified quickDASH-9 scale to measure the quality of recovery after hand burn injury to ensure better care delivery. The study was performed in the following steps: (1) Modification of the Arabic modified quick DASH-9 questionnaire with respect to Egyptian accent. (2) Cross cultural adaptation of the upper extremity functional Index-15 through the translation process from the original English version of the UEFI-15 scale into Arabic one according to the international published guidelines, (3) psychometric properties of the two questionnaires were measured (content validity, reliability and evaluation of responsiveness of Arabic modified quick DASH-9 questionnaire and compared it with Arabic UEFI-15 one. The content validity was measured by seeking expert opinions by using Index of content Validity (ICV), internal consistency by measuring cronbach{u2019}s alpha and test-retest reliability by asking fifty patients (22 male+28 female) with dorsal hand burn injuries, their ages were ranged from 16 to 60 years old to fill the Arabic modified quick DASH-9 scale and Arabic upper extremity functional Index-15 (UEFI-15), average two days interval, they were asked to re-fill it again. Reliability coefficient was measured also by kappa for both Arabic modified DASH-9 and UEFI-15. Responsiveness was assessed by asking the patients to fill the two questionnaires after 3 or 6 sessions of physical therapy and estimating their standardized response mean (SRM), effect size ES and wilcoxon signed ranked test
