Neuroprostheses are devices that use electrodes to interface with the nervous system and aim to restore function that has been lost due to spinal cord injury (SCI). Neuroprostheses can restore some motor, sensory, and autonomic functions by stimulating various parts of the nervous system including muscles, nerves, spinal cord, or the brain. Many people with SCI feel that restoration of walking and/or standing ability would have a positive impact on their quality of life. Neuroprosthetics is a part of new technology taking part in clinical practices along with neurorehabilitation. Hybrid systems combining rehabilitation robotics with neuroprosthesis emerge as promising techniques that blends together technologies that could overcome the limitations of each individual one.
