FootSim possible contribution to biomimetic stimulation patterns for tactile feedback restoration in future neuroprosthetics

In a possible scenario, the user will be fitted with a leg prosthesis collecting real-time spatiotemporal pressure data via a sensorized insole (bottom left). This data will be provided as an input to the FootSim model. The model would convert the artificial pressure profiles into realistic neural response patterns (top, blue shaded box). FootSim output could be potentially used for generating biomimetic stimulation policies (bottom right). Neurostimulator would generate these paradigms, and this type of stimulation could be used to transmit to the subject the information recorded with the insole in a future possible scenario.
