Registration Number
NCT06400043
Lead Sponsor
University Ghent
Brief Summary

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..

Detailed Description

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). This is a treadmill linked to a virtual environment used to analyse and train gait at the Children's Rehabilitation Centre of Ghent University Hospital. The data from children with DCD will be compared with typically developing children. In this study, only children with DCD will be included and the data resulting from this study will be compared to the data from the previous study in typically developing children (ID: B670201942108).

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. While walking at comfortable walking speed, two short games will be played i.e. dual-tasking. This involves both a cognitive (Stroop Colour-Word Test) and a motor (requires the use of the arms) dual task projected in the virtual environment of the GRAIL. The cognitive and motor task will be performed both while standing still (single tasking: ST) and while walking (dual tasking: DT). Simultaneously, kinetics, kinematics, and EMG data will be collected for 3D gait analysis. Using muscle synergy analysis (based on EMG data), the degree of gait automatization will be analysed. The data from children with DCD will be compared with typically developing children to determine whether a reduced gait automatization can be observed in children with DCD.

Parents will be asked to complete a screening list (CVO/DCD-Q) for motor problems in daily life. This aims as a support to the motor test (M-ABC-2), together providing additional insight into children's motor functioning (in daily life).
