تأثیر یکپارچگی ادراک شده و مداخله حرکتی در کودکان مبتلا به اختلال در هماهنگی رشد

This is the first study that has investigated the effect of an integrated perceived competence and motor intervention (intervention group) on motor performance, self-perceptions, and physical activity compared with a motor intervention (care-as-usual group) in children with DCD. We made the perceived competence component explicit by providing positive, specific, and progress feedback to enhance children’s self-perceptions. Also, this is one of the first studies that has investigated the effect after both 12 treatment sessions (trial end-point) and after 3 months of no intervention (3-month follow-up). We found no differences between the intervention and the care-as-usual group, but children improved their motor performance and increased (most) of their self-perceptions after 12 treatment sessions, while physical activity remained the same. The improvement was still present at the 3-month follow-up. We also benchmarked our results about self-perceptions and physical activity to a group of typically developing children. Self-perceptions in children with DCD had improved to the level of typically developing children after 12 treatment sessions, but their physical activity levels remained significantly lower. This result was the same at the 3-month follow-up, except for perceived athletic competence, which was lower in children with DCD at the 3-month follow-up. In accordance with previous intervention studies that have investigated children with DCD, we found large intra-group variability in the change in motor performance and self-perceptions in children with DCD. We argue that we need to better understand why some children with DCD improve and others do not after a motor intervention.
