About this trial
The aim of the study is to collect data in children with developmental coordination disorder (DCD) aged between 7 and 17 years for analyses of the gait pattern while walking at the Gait Real-time Analysis Interactive Lab (GRAIL) at the university hospital of Ghent.
Children with DCD will be asked to take a motor test (M-ABC-2) as well as walk on the treadmill during a single session of approximately 3 hours.
The following data will be collected on the GRAIL while subjects walk at different gait speeds: 3D kinematics, kinetics, and EMG.
Additionally, 3D kinematics, kinetics, and EMG data will be collected when performing either a cognitive (Stroop Color and Word Test) or motor (requiring arm swing) dual-task while walking at comfortable walking speed..

Treatments tested in this trial
Cognitive dual-task
Other interventionParticipants will be asked to walk at comfortable walking speed while playing an additional cognitive task, namely the Stroop Color and Word Test.
Motor dual-task
Other interventionParticipants will be asked to walk at comfortable walking speed while playing an additional motor task, namely a game that requires arm swing to hit the targets.
