Figure 3.

Visual feedback for the pilot trial. The yellow legs of the patient avatar (figure on the right) represent the actual movements of the Lokomat legs. The red figure on the left demonstrates the desired leg movements. Subjects are instructed to match the movements of the red figure as close as possible. For fine-tuning of the movements, subjects can focus on the semi-transparent red "ghost legs" that are overlaid to the legs of the patient avatar.
