World's First "NorthBrain 1" Brain-Computer Interface Combined with Spinal Cord Electrical Stimulation for Paraplegia Marks 1-Year Milestone with Transition from Complete Paraplegia to ASIA C

Background

A 30-year-old man known by the pseudonym Zhiming suffered a traumatic spinal cord injury at the T12-L1 level approximately five years before 2026. The injury resulted in complete paraplegia, classified as ASIA A, with loss of sensory and motor function in the lower limbs and no significant improvement despite conventional rehabilitation therapy. On May 19, 2026, Zhiming marked the one-year anniversary of his groundbreaking surgery by cutting a cake at Xuanwu Hospital, Capital Medical University in Beijing.

For decades, medical doctrine held that functional recovery from late-stage complete spinal cord injury was irreversible once neural pathways were fully severed. In 2025, a neurosurgery team at the hospital led by hospital president Zhao Guoguang and chief physician Duan Wanru performed the world's first simultaneous implantation of the 'NorthBrain 1' invasive brain-computer interface and a sequential spinal cord electrical stimulation system in such a chronic patient. The procedure was part of an innovative combined approach also incorporating exoskeleton-assisted training.

What was achieved

One year after the May 2025 surgery, clinical assessment confirmed that Zhiming's neurological function had improved from ASIA A (complete injury) to ASIA C (incomplete injury). He regained some voluntary lower limb movement, the ability to stand and walk with assistive devices including the exoskeleton system, and the capacity to perform basic self-care activities such as dressing and washing. Improvements in autonomic functions, including bowel and bladder control, were also reported. His wife was able to return to work as he gained greater independence.

This case represents the first reported transition of this kind using the NorthBrain 1 system combined with spinal cord stimulation for chronic paraplegia. Reports from the hospital and corroborating Chinese media state that the outcome challenges the longstanding view of permanent irreversibility in late-stage complete spinal cord injuries, demonstrating neural pathway reconstruction through the multimodal intervention. Follow-up included intensive rehabilitation in a specialized laboratory followed by home-based training with remote monitoring.

How it works

The technique involves implanting the NorthBrain 1 brain-computer interface in the patient's skull to record signals from the motor cortex. This wireless, high-channel system captures the brain's intended movement commands with high precision and low latency. These decoded signals are then used to trigger a timed electrical stimulation system implanted along the spinal cord, positioned to activate neural circuits both above and below the injury site without directly invading the damaged area.

The stimulation follows a sequential pattern designed to mimic natural neural firing, helping to reactivate dormant spinal networks. This is integrated in a closed-loop manner with a standing exoskeleton that translates the brain-derived commands into physical limb movements and gait training. The combined system effectively constructs an 'electronic life bridge' that bypasses the scarred injury zone at T12-L1, allowing motor intent from the brain to produce functional output in the paralyzed limbs. The approach relies on repeated training to strengthen new connections between brain, stimulated spinal cord, and musculoskeletal system.

What it means for international patients

The case illustrates ongoing clinical research in China into brain-computer interfaces and neuromodulation for chronic spinal cord injury. Xuanwu Hospital maintains an International Medical Department that provides services in English and French, supporting patients seeking specialized neurological care. The hospital's expertise in neurosurgery, neurology, neurointervention, and rehabilitation medicine positions it as a center for complex cases involving spinal disorders.

International patients considering similar advanced interventions should contact the hospital directly to confirm current availability, eligibility criteria, and individual suitability. Assessments would require comprehensive review of medical history, imaging, and current functional status, as this remains an innovative approach applied in specific research and clinical contexts. No information on costs or guarantees of outcomes for international cases was reported in the sources.

About the hospital

Xuanwu Hospital, Capital Medical University is a large tertiary Grade III Class A comprehensive hospital located at 45 Changchun Street in Beijing's Xicheng District. Established in 1958, it is recognized as the birthplace of neurosurgery in China, founded by Professor Zhao Yicheng. The neurosurgery department has grown into a major national center with over 400 beds dedicated to neurological care, advanced intraoperative imaging, navigation, robotics, and more than 14,000 neurosurgical procedures annually.

It is a leading institution for neurological diseases, including stroke, movement disorders, spinal conditions, and functional neurosurgery. The hospital hosts national key disciplines and training bases in neurology and neurosurgery and operates an International Medical Department to accommodate overseas patients. It is affiliated with Capital Medical University and functions as a hub for clinical research, education, and treatment of complex neurological disorders.
