Gert-Jan Oskam, who suffered a debilitating cycling accident twelve years ago, is now walking again with the help of a groundbreaking brain-spine interface device. Developed by neuroscientist Grégoire Courtine and his team, the device uses implants in Oskam’s skull to detect electrical activity in his brain’s cortex when he thinks about walking. The information is then wirelessly transmitted to a spinal pulse generator, allowing Oskam to control the stimulation and movement of his legs. After 40 rehabilitation sessions, Oskam has regained the ability to move his legs voluntarily and walk short distances without the device. The brain-spine interface represents a significant leap forward for individuals with spinal cord injuries and could pave the way for further advancements in rehabilitation.
