Children with Down Syndrome (DS) often show impaired motor control, and walk with a slower speed and a shorter step length than typically developing (TD) children. When negotiating an obstacle, children with DS often stop for a longer duration, choose a more conservative crawling strategy and display a smaller toe clearance than their TD peers.
