During the baseline condition, each participant sat with the prosthesis elevated while an electrode contact delivered stimulation to the nerve. Participants then drew the perceived location of the evoked percept on a blank diagram of the intact foot and leg, represented here as one heat map per contact. Red areas indicate regions that were drawn in all fifteen trials. The forefoot region of interest (ROI) was classified as the primary ROI for contacts F1-F3, and the rearfoot ROI was classified as the primary ROI for contacts R1-R3.
