On Laterally Perturbed Human Stance: Experiment, Model, and Control

Figure 5

Unfiltered angular trajectories for valid trials of the experiment. In the (a) plot are the perturbations to the left, and in the (b) are perturbations to the right. The solid line (blue) is the hip the dashed line (red) is the ankle angle trajectory. All the “extreme” hip angle peaks stem from participant (4).
