Scientists at Fudan University in Shanghai have developed a brain-spinal implant that is helping paralyzed patients walk again. This new technology uses tiny chips placed in both the brain and the spinal cord to reconnect lost signals, allowing the nervous system to function again. Unlike traditional brain-computer interfaces, this device works by directly stimulating dormant nerves, helping the body heal faster.
The results are already life-changing. Four paralyzed patients have taken steps just hours after surgery, and one man even walked again within two weeks. This development brings new hope to millions around the world who are living with spinal cord injuries.
One of the patients, a 34-year-old man named Lin, became paralyzed after falling and suffering a brain hemorrhage. On January 8, he underwent surgery at Zhongshan Hospital. Doctors implanted small electrode chips, each just 1mm in size, into both his brain and spinal cord. Within just 24 hours, Lin could lift both his legs.
By day 14, Lin was walking again with the help of a standing frame. He could even step over obstacles and cover more than 16 feet. It was something he thought he would never do again.
Lin later shared his experience, saying, “My feet feel warm and sweaty, and there is a tingling sensation. When I stand, I feel the muscles in my legs contracting.” He also said he could feel when he needed to go to the bathroom, showing that deeper nerve sensations were returning.
What makes this technology different is how fast it works. In past studies, like one in Switzerland, similar effects took at least six months to appear. But the Chinese implant showed results in just two weeks. The technique is also minimally invasive, meaning it causes less damage during surgery.
The secret lies in what researchers call a “neural bypass.” The electrode chips read signals from the brain and send them directly to the spinal cord. This helps the nerves “wake up” and form new pathways — a process called neural remodeling. The hope is that with time and therapy, the nervous system can rewire itself, removing the need for long-term assistive devices.
This technology is fully developed in China, showing the country’s growing strength in medical science and innovation. According to Professor Jia Fumin from the Fudan Brain-like Intelligence Science and Technology Research Institute, “In the past, everyone was familiar with high-end medical equipment from abroad, but now we have entered uncharted territory, achieving the world’s first new generation of original brain-spinal interface system solutions.”
The research team used AI to help create a smart nerve connection between the brain and spinal cord. In total, four patients received the implant — one in January, and three more in February and March. All of them showed strong signs of recovery within weeks of their operations.
Professor Jia added, “The therapeutic outcomes for these paraplegic patients met or even surpassed our expectations, preliminarily validating the feasibility of this next-generation BSI solution.”
There are about 3.74 million people in China living with spinal cord injuries, with 90,000 new cases each year. Globally, the number is even higher. Until now, these injuries were considered permanent.
Even Elon Musk’s Neuralink, a famous brain-computer interface company, works on the belief that paralyzed limbs can’t be saved — instead focusing on using robotic arms controlled by the brain.
But this Chinese brain-spinal interface changes that thinking. It doesn’t just send brain signals to machines — it helps the body itself recover and heal. Unlike Neuralink’s system, which connects the brain to computers, Fudan’s device rebuilds the body’s natural pathways. This means patients could eventually live without the need for external machines.
“If we implant a spinal interface and combine it with three to five years of rehabilitation training, the patient’s nerves can reconnect and be reshaped,” said Professor Jia. “Ultimately, we may free patients from device dependence.”
