A brain-to-computer technology that can translate thoughts into leg movements has enabled a man paralyzed from the waist down by a spinal cord injury to become the first such patient to walk without the use of robotics. The feat was accomplished using a system allowing the brain to bypass the injured spinal cord and instead send messages through a computer algorithm to electrodes placed around the patient’s knees to trigger controlled leg muscle movements.

The slow, halting first steps of the 28-year-old paraplegic Mark Pollock were documented scientists from UCLA in a preliminary study published in the British-based Journal of NeuroEngineering and Rehabilitation.
