Paralyzed Man Walks Naturally, Thanks to Wireless ‘Bridge’ Between Brain and Spine

A new study published in Nature reports a breakthrough in restoring mobility to individuals with spinal cord injuries. Gert-Jan Oskam, who lost the ability to walk in a cycling accident, was able to take more fluid steps and navigate obstacles with the help of a brain-spine interface. The interface allows brain waves indicating the desire to walk to be transmitted from a device implanted in Oskam's skull to a spinal stimulator, bypassing the damaged tissue and delivering electrical pulses to the spinal cord. The results show greater recovery compared to previous methods of spinal stimulation alone, and Oskam can even walk with crutches when both devices are turned off. While the study is a proof of concept with a single participant, it represents a significant advancement in bridging the communication gap between the brain and lower body in individuals with spinal cord injuries. Further research is needed to determine its effectiveness for a broader range of patients and to refine the technology for more seamless integration and improved outcomes.
