A groundbreaking advancement in the treatment of quadriplegia has been achieved at the Rehabilitation Medicine Center of the Second Norman Bethune Hospital at Jilin University in Changchun, Jilin province. Liu Boqi, a 35-year-old traffic officer who suffered severe injuries in a car accident in December 2024, is now relearning how to walk thanks to an innovative spinal cord interface technology. Initially, Liu was diagnosed with severe lung damage, fluid in his chest, and a fracture and dislocation of the third cervical vertebra. Although surgery saved his life, he was left paralyzed with no movement in his limbs. Professor Wu Minfei, a spinal surgery specialist, introduced Liu’s family to an experimental technology involving an implanted device that reconnects damaged nerve pathways and provides precise electrical stimulation to restore communication between the brain and the body. The device was implanted in January 2025, and within six hours, Liu’s fingers and toes began to twitch. Over the following months, his muscle strength and sensation gradually improved. By combining the interface therapy with an exoskeleton robot, Liu was able to take his first steps. After three months of intensive rehabilitation, he achieved the remarkable milestone of walking independently with a walker. This case represents a significant breakthrough in treating high-level quadriplegia, and the hospital has since applied the method to other patients with promising results. Professor Wu expressed optimism, stating, ‘I believe more paralyzed patients will have a chance of standing up and walking again in the future.’
