DMD & BMD – CLINICAL: P.58 Hypermobility in young boys with Duchenne muscular dystrophy and its effect on attainment of North Star Ambulatory Assessment functional skills

Abstract

Children with hypermobility tend to achieve motor milestones on average later than peers without. This study looked at the prevalence of hypermobility in a sample of the Duchenne muscular dystrophy (DMD) population and aimed to determine if hypermobility has an impact on attainment of North Star Ambulatory Assessment (NSAA) functional skills. This is a retrospective study of 112 boys with DMD aged between 3 and 8 years (±3 months), concentrating on the early phase. During clinical appointments each boy was assessed using the NSAA and joint ranges measured.
