Muscle Thickness in Lower Extremity and Locomotor Functions in Children With Down Syndrome and Typical Developing Peers

Muscle thickness may serve as an indicator of muscle strength and coordination, contributing to the understanding of their impact on locomotor performance in DS children, particularly with regard to the tibialis anterior muscle, which is essential for dorsiflexion and foot placement control. The prioritisation of stability for gait and running is essential due to reduced velocity, increased step width and shorter step length in DS children.
