Experimental setup and responses. (a,b) Setup for posteroanterior (PA) and anteroposterior (AP) direction. (c) Typical time response and some characteristic time instants, \(t_0\): onset of perturbation, \(t_1\): maximum excursion, \(t_2\): recovery to normal posture, \(t_3\): end of the trial. (d) Sample time signals measured during PA (red) and AP (blue) setups.
