A groundbreaking digital brain–spine bridge empowers tetraplegic patient to walk naturally after spinal cord injury Nature EPFL_en spinal spinalcord spinalcordinjury brainspinebridge spine bridge walk
By Neha MathurMay 26 2023Reviewed by Lily Ramsey, LLM In a recent article published in Nature, researchers developed a groundbreaking wireless digital bridge that helped a chronic tetraplegia patient to walk naturally on complex terrains.Furthermore, this highly reliable brain-spine interface calibrated within a few minutes remained stable over one year, even during independent use at home.
A single-participant study The team tested and validated this digital bridge in a 38-year-old male who sustained an incomplete cervical spinal cord injury ten years prior . Further, they planned pre-operative procedures to optimally position the BSI implants over the spinal cord and brain. It enabled the participant to achieve a fivefold increase in hip flexor muscle activity within five minutes of calibration to generate torque with an accuracy of 97% compared to attempts without the BSI.
During 40 sessions of neurorehabilitation, including physiotherapy sessions, the participant accomplished walking, balancing, and managing single-joint movements with BSI.
