Active foot placement control ensures stable gait: Effect of constraints on foot placement and ankle moments
Step-by-step foot placement control, relative to the center of mass (CoM) kinematic state, is
generally considered a dominant mechanism for maintenance of gait stability. By adequate …

Lower extremity joint-level responses to pelvis perturbation during human walking
The human leg joints play a major role in balance control during walking. They facilitate leg
swing, and modulate the ground (re) action forces to prevent a fall. The aim of this study is to …

Ankle muscles drive mediolateral center of pressure control to ensure stable steady state gait
During steady-state walking, mediolateral gait stability can be maintained by controlling the
center of pressure (CoP). The CoP modulates the moment of the ground reaction force …

A controller for walking derived from how humans recover from perturbations
Humans can walk without falling despite some external perturbations, but the control
mechanisms by which this stability is achieved have not been fully characterized. While …

[HTML][HTML] The effect of anteroposterior perturbations on the control of the center of mass during treadmill walking
Shifts of the center of pressure (CoP) through modulation of foot placement and ankle
moments (CoP-mechanism) cause accelerations of the center of mass (CoM) that can be …

Foot placement modulation diminishes for perturbations near foot contact
Whenever a perturbation occurs during walking we have to maintain our balance using the
recovery strategies that are available to us. Foot placement adjustment is often considered …
