Figure 1: Schematic of the proposed rehabilitation for sensory impairments: (a) from the viewpoint of system engineering, sensory impairments are considered as input failure in a system, leading to dysfunction of the entire system. (b) The dysfunction can be corrected through repair or replacement by another input component, where enhancement of kinesthetic feedback or replacement with another sensory modality allows intervention for the dysfunction through reestablishment of motor-sensory loop.
