Effects of functional level on balance in children with Duchenne Muscular Dystrophy

Introduction: This study was planned to compare the static and dynamic balance in children with Duchenne Muscular Dystrophy (DMD) at different functional levels with each other and with healthy peers. Material and methods: Sixty nine children between the ages of 6 and 11 were included in this study where 52 of them were diagnosed with DMD in Level I (18 patients), Level II (17 patients), and Level III (17 patients) according to Brooke Functional Classification Scale and 17 of them healthy peers were included. In order to assess static and dynamic balance pediatric functional reach test (PFRT) and timed up and go test (TUGT) were used. Results: When compared in terms of the TUGT, differences were found between all groups, i.e. Level 1 and 2, Level 2 and 3, Level 1 and 3, Healthy peers and Level 1, Healthy peers and Level 2, and Healthy peers and Level 3 (p < 0.0083). When compared in terms of the PFRT in the standing positions, there was difference between level 3 and healthy peers (p < 0.0083), but not between the other groups. Conclusions: We found poor functional level in DMD to affect the dynamic and static balance parameters in this study. The dynamic balance of a child with DMD at Level 3 is decreased to a third of a healthy peer. (C) 2017 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.
