How do toddlers increase their gait velocity?
Elsevier: Gait & Posture
This study examines the components of the development of velocity during early walking. Eight children with typical development were followed during their first 5 months of walking experience. Velocity, cadence, and step length were measured. Normalized step length did not change over this time, however, normalized cadence increased. This indicates that an increase in cadence is contributing to early increases in walking velocity.
