There are studies investigating the dual-task effect in sitting, standing up without sitting and walking in children with spastic CP. Some of these studies investigated motor-motor, some of them motor-cognitive dual-task states, and children with CP were compared to typically developing children. In all these studies, it is clearly seen that children with CP have more dual-task complexities than their typically developing peers. Some of these studies draw attention to dual-task education in children with CP. However, other than a randomized controlled study and a case report in the literature, we did not find any studies investigating the effectiveness of dual-task training in children with CP. When the literature is examined in detail, there is no study that examines the effect of dual-task exercise programs on walking activities and children's participation in daily life in children with CP.

This study has been planned based on this deficiency in the literature. Based on ICF, This study has been planned dual-task training for children with CP.
