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..
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
They have an official DCD diagnosis;
Are aged between 7 and 17 years old;
Can walk at least 15 minutes consecutively;
Have good or corrected vision.
Disqualifiers
They suffer from a neurological disorder;
Take medications that affect gait and balance;
Have undergone surgical procedures on the lower limbs in the past;
Experience pain in their lower limbs or back at the time of testing.
Trial design
Single group
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.
Treatment groups
Trial outcomes
Primary outcomes
Kinematics
3D kinematics of lower and upper limb joints while walking (degrees)
Kinetics
3D kinetics of lower limb joints while walking (Nm)
EMG
Muscle activity of 16 lower limb muscles (microvolts)
Muscle synergies
Synergy analysis will be conducted using the EMG data (variance accounted for -VAF)
Secondary outcomes
Gait deviation index
Based on kinematics, the lower-limb gait deviations will be calculated (degrees)

M-ABC-2
Standardized tool to identify motor functioning in children (standard score between 1 and 19) Standard scores indicate: * Significant motor difficulty: standard score \< 6 * Minor motor difficulties: standard score 6 or 7 * No motor difficulty: standard score \> 7
