Reinforced Feedback in Virtual Environment for Plantar Flexor Poststroke Spasticity Reduction and Gait Function Improvement

Figure 3

Different trajectories proposed to patients in the virtual scenario. (a) Star of numbers with different directions to follow, moving the foot on the ground without losing contact with the plant. In (b) and (c), the ideal path proposed by the physiotherapist (red) and the different tests performed by the patient (yellow) are shown. As can be seen, the executed trajectories (yellow) approximate the proposed ideal trajectory (red) from pretraining (b) to posttraining (c).
