Stepping is a common protective strategy for dynamic balance recovery following external perturbations of stance. The present study investigated the threshold for triggering a step during force-controlled forward perturbations of different durations delivered at waist level, and confronted the experimental results with a simple biomechanical model that could predict when a subject had to step.
