Step length of best case response to perturbations P1-5.

Step length response corresponding to unassisted gait (UA), free moment with action on thigh (FMTh), joint moment with action on thigh and reaction on trunk (JMTh-Tk), joint moment with action on thigh and reaction on contralateral thigh (JMTh-Th), free moment with action on shank (FMSk) and joint moment with action on shank and reaction on thigh (JMSk-Th) for perturbation types P1-P5, as well as unperturbed gait (UP) as reference. Metrics reported are the step length of the perturbed limb (SLP), and step length of the trailing limb (SLT) of the recovery step. (TEX)
