DMD – BIOMARKERS & OUTCOME MEASURES

Abstract

S85 tasks. Mean intra-rater reliability (ICC) for 9 raters ranged from 0.82 to 0.98 for all movement tasks. There were statistically significant differences between known severity groups for all movement tasks. The DVA correlated strongly with related PODCI constructs of physical function and weakly with unrelated constructs. The results suggest that the DVA is highly reliable both between and within raters. The DVA can detect differences between severity groups, and it correlates strongly with related constructs and weakly with unrelated constructs, thus demonstrating construct validity.
