This study included patients with MS between 0-5,5 score according to the Extended Disability Status Scale (EDSS). DTQ was used to assess the frequency of difficulties associated with daily tasks involving the dual-task. Additionally TUG with dual-task and 9-HPT with dual-task were applied to the patients. An experienced physiotherapist applied all these tests. In order to measure test-retest reliability, a retest was carried out by the same physiotherapist one week following the first evaluation. The construct validity of DTQ was tested by Pearson's correlation coefficient.
