Première mondiale : une personne paraplégique pilote sa marche par la pensée
全球首例：瘫痪患者通过意念控制行走
一项法瑞合作研发的脑-脊髓接口技术取得重大突破，首次使瘫痪患者能够通过意念控制双腿行走。该研究由法国原子能与替代能源委员会（CEA）等机构参与，成果于2023年5月24日发表在《自然》杂志上。
这项技术通过植入式设备，在大脑与脊髓之间建立了一条"数字桥梁"。当患者产生行走意图时，大脑信号被实时解码并转化为电刺激指令，直接激活脊髓中控制腿部肌肉的区域，从而绕过受损的神经通路实现自主步态控制。
临床测试中，一位长期瘫痪的患者在康复训练后，已能借助助行器自主行走。该系统不仅实现了运动功能重建，还显示出促进神经重塑的潜力——在设备关闭后，患者仍保留部分恢复的行走能力。
该突破标志着神经工程学在瘫痪治疗领域的里程碑进展，为脊髓损伤患者带来了新的康复希望。研究团队表示将继续优化系统稳定性，并探索更广泛的应用场景。
In a world-first medical breakthrough, a person with paraplegia has regained the ability to walk by controlling the movement of his legs through thought alone. This achievement was made possible by a novel brain-spine interface (BSI), developed through a Franco-Swiss research collaboration involving France’s Atomic Energy and Alternative Energies Commission (CEA).
The pioneering results, published in the journal *Nature* on May 24, 2023, mark a significant leap in neurotechnology. The system works by decoding movement intentions from brain signals recorded via an implant over the brain’s motor cortex. These signals are wirelessly transmitted and processed in real-time by a wearable computer, which then translates them into commands for electrical stimulation of the spinal cord. This stimulation activates the leg muscles, effectively bypassing the damaged section of the spinal cord and restoring voluntary control of stepping.
The patient, a 40-year-old man who had been paralyzed for over a decade following a spinal cord injury, was able to walk naturally on ground, climb stairs, and navigate complex terrain using the BSI. After extensive calibration and training with the system, he achieved a remarkable degree of mobility and independence, including the ability to stand and walk for sustained periods without requiring upper body support from a walker.
This research, led by teams at the CEA, the University of Lausanne, and the Lausanne University Hospital (CHUV), demonstrates the feasibility of a digital bridge to restore communication between the brain and spinal cord. The scientists emphasize that the technology is still in an experimental, proof-of-concept stage, but it opens a promising pathway for future clinical applications to improve motor function in individuals with paralysis.
Pour la première fois, une personne paraplégique a pu marcher en pilotant ses jambes par la pensée. Ceci grâce à une interface cerveau-moelle épinière développée dans le cadre d’un partenariat franco-suisse impliquant le CEA. Ces résultats sont publiés dans la revue Nature du 24 mai 2023.
