A medical team at the Second Hospital of Jilin University in northeast China's Jilin Province has successfully helped a man who was completely paralyzed regain the ability to stand and walk through coordinated rehabilitation using a "spinal interface and exoskeleton robot" system.
This breakthrough represents the world's first successful case where spinal interface technology has enabled a patient with complete high-level paralysis to regain voluntary movement, according to the hospital in Changchun City, capital of the province.
Restoring voluntary movement in patients with high-level paralysis has long been a global medical challenge.
Liu Boqi, 35, a traffic police officer from Fuyu City in Jilin Province, was severely injured in a car accident while on duty in December 2024.
The crash caused a serious cervical spinal cord injury, leaving him completely paralyzed and breathing with difficulty.
Wu Minfei, chief physician of the hospital's spine surgery department, performed an emergency surgery immediately after the accident. Although the operation saved Liu's life, it did not restore any movement in his limbs.
Faced with this challenging situation, Wu's team decided to attempt an innovative approach that might give the patient a chance to regain voluntary control.
"We took a bold step by directly applying the spinal interface technology to the injured part of his spinal cord. While we had done some preliminary research before, this was the first time we used it in such a complex surgery," said Wu.
According to Wu, in patients with severe cervical spinal injuries, the nerve connection between the brain and spinal cord is completely cut off. The technology involves implanting tiny microelectrodes at the injury point to stimulate and regulate the nerve cells responsible for limb movement, helping patients regain voluntary control over their paralyzed limbs.
"After we activated the spinal interface and started electrophysiological modulation, the patient's hand began to move. That moment was thrilling. It proved that the neural circuit from the brain to the spinal cord to the hand was reconnected," Wu said.
Encouraged by the initial progress, Wu's team continued two weeks of intensive nerve regulation therapy, during which Liu's muscle strength improved significantly.
Three months later, doctors tailored a rehabilitation program that integrates the spinal interface with an exoskeleton robot. With the precise nerve signals from the spinal interface and physical support from the exoskeleton, Liu was able to take his first step since the accident.
"After the spinal interface surgery, we provided systematic rehabilitation including electrical stimulation, acupuncture, biofeedback, and manual therapy. His muscle strength, balance, and overall function have greatly improved. Now he can stand and walk with the help of the exoskeleton robot," said Zhang Haina, associate chief physician of the hospital's rehabilitation medicine center.
For Liu, the experience has been life-changing, and he is eager to see himself walk again.
"It feels incredible to stand up and walk again. I'm full of hope for the future," said Liu.
