Losing the ability to walk is one of the most disabling impairments after a spinal cord injury. Among the technologies developed to recover walking ability, stimulating the person’s own muscles or using active orthoses (also called robotic exoskeletons) are promising areas in which research and development are being done. While several drawbacks hamper widespread use of each technology, combining the technologies can overcome the disadvantages of each. One such combined system is the hybrid exoskeleton (or hybrid orthosis). We review the hybrid exoskeletons developed to restore walking ability, present recent developments in the field, and identify areas in which more research is need.
