Kinetic patterns of treadmill walking in preadolescents with and without Down syndrome.

Highlights: [•] We study vertical GRF and impulse of treadmill walking in children with DS and TD. [•] Children with DS produce less efficient propulsion during treadmill walking. [•] A faster speed helps children with DS increase propulsive duration and impulse. [•] External ankle load helps children with DS increase propulsive force and impulse. [ABSTRACT FROM AUTHOR]
