Shanghai's first case of brain-computer interface implantation patient one year after surgery: with high-level paraplegia, he shows signs of nerve remodeling.

One year ago, as the first participant in the clinical trial of brain-computer interface in Shanghai, 38-year-old Xiao Dong underwent brain-computer interface implantation surgery at Huashan Hospital. After a year of postoperative rehabilitation training, Xiao Dong, who could not grasp with his hands before, can now not only pick up small steel balls and pills, but also hold a pen to write. What is even more gratifying is that the brain-computer interface is quietly helping him slowly recover his nervous system. He, who used to have urinary and fecal incontinence, can now defecate more regularly and even feel some itching in his waist and legs. Yesterday, Xiao Dong completed his one-year postoperative physical examination at Huashan Hospital. Preliminary examination results confirmed his feelings: his hand movement score improved by 20 points compared to before the surgery, and the degree of spinal cord injury decreased from grade B to grade C - indicating signs of nerve remodeling. "This is truly a miracle!" Xiao Dong said excitedly in an exclusive interview with our reporter, "A year ago, I couldn't imagine today would come, it is technology that has brought me new hope for life."
