Reliability and Validity of the Turkish Version of the Upper Limb Short Questionnaire in Duchenne Muscular Dystrophy

Purpose: This study aimed to evaluate the construct validity and reliability of the Turkish version of the Upper Limb Short Questionnaire (ULSQ) in Duchenne muscular dystrophy (DMD). Materials and methods: A total of 41 children with DMD have participated in the study. Upper and lower extremities functional levels were assessed with Vignos Scale and Brooke Upper Extremity Functional Rating Scale, respectively. The construct validity of the questionnaire was determined using the correlation between the ULSQ and ABILHAND-Kids. The Cronbach alpha value was calculated to determine internal consistency. To determine test-retest reliability, 17 randomly selected children were evaluated seven days after the first evaluation, and the \"Intraclass Correlation Coefficient (ICC)\" value was calculated.
