Spinal cord interface for paralysis
A spinal cord interface is a thin electrode strip placed on the spinal cord at the level of the injury. It delivers precise electrical pulses that aim to wake up nerve pathways that still exist but no longer carry signals well. It is experimental, was developed at a Chinese hospital, and is not an approved treatment.
Who it may suit
- Adults with a cervical or upper spinal cord injury who have lost much or all movement below the injury
- People whose spine and general health are stable enough for surgery and travel
- Patients and families ready for months of intensive rehabilitation, with realistic goals
What happens
- Case review of your scans, injury level, ASIA grade and rehabilitation records by the surgical team
- In-person assessment in China to confirm suitability and plan the implant
- Surgery to place the electrode strip, then careful switching on and adjustment of the stimulation
- Intensive rehabilitation in China, followed by a training plan to continue at home
Plan for about 6 to 10 weeks in China, then continued rehabilitation at home. This is an estimate, and the team advises per case.
In Canada, spinal cord stimulation to restore movement after injury is available only in research studies, for small numbers of people.
Indicative cost in China
about C$40,000
Usually covers the operation and the implant. Rehabilitation, a longer hospital stay and travel are extra and are confirmed for each case.

How it works
After a spinal cord injury, the nerves below the damage often still work, but signals from the brain no longer get through well. Electrical stimulation of the spinal cord tries to raise the activity of these nerve circuits so the weak signals that remain can trigger movement again. Rehabilitation then trains the body to use those pathways. Research teams in Switzerland have shown this approach in small numbers of people, including a brain-spine interface published in Nature in 2023.
The Chinese version is a strip of electrodes, about 56 mm long and 7.5 mm wide, placed over the injured neck segments. In January 2025 a Chinese spinal surgery team implanted it in a 35-year-old man. He had been injured on duty a month earlier, with a fracture-dislocation in his neck, and was reported to have a complete injury, paralysed from the neck down and unable to breathe on his own. He was reported to move his fingers and toes about six hours after the device was switched on. After about three months of training he could lift his legs. Within roughly six to nine months of his injury he stood and took steps, first with an exoskeleton and then with a walker, and over short distances on his own. His arm strength largely returned, though his balance is still impaired.
This is one reported case, and it is experimental. The hospital says it has used the method on several more patients with encouraging results, but it has not published numbers. No peer-reviewed paper or trial registration has been reported yet. We do not know how many people improve, how much, for how long, or who is most likely to benefit. Some people recover a little on their own after an injury, which makes single cases hard to judge.
Potential advantages
- Aims to restore some movement in the legs and arms, not only to support the body from outside
- The electrode strip sits on the spinal cord and does not need brain surgery
- In the reported case, early movement appeared within hours of switching on
- Developed and used by a spinal surgery team with direct experience of the method
- Not available outside research studies in Canada, the US or Europe
What to prepare for a specialist review
- Could I be considered? The team will look at your injury level, whether it is complete or incomplete (your ASIA grade), time since injury, your age and general health, and your breathing, skin and bladder status
- MRI and CT reports of your spine, with the images on disc or by secure download
- The date and cause of your injury, and the injury level confirmed by your doctors
- Your most recent ASIA assessment and any strength or movement scores
- Surgery notes from any spinal operation, including metal or devices already in place
- Rehabilitation summaries describing what you can do now and the equipment you use
- Breathing support, pressure sores, bladder and bowel care, infections and current medicines
Questions to ask the treating team
- How many patients have you treated with this method, and what happened to them, including those who did not improve?
- Based on my injury level, ASIA grade and time since injury, what realistic change could I expect?
- What are the risks of the surgery and the device, and what happens if it needs to be adjusted or removed?
- How long is the rehabilitation in China, and what training will I need to continue at home?
- Who supports the device after I return home, and what follow-up visits will I need?
Things to know. This is an experimental surgery with no published trial results yet. Risks include infection, bleeding, spinal fluid leak, pain, and the device moving or failing. Results vary, and no one can promise that you will walk. Rehabilitation at home remains essential.
Why an introduction matters
Many of China’s leading specialists work in busy public hospitals without international patient offices. They rarely answer enquiries from abroad directly, and a file sent without an introduction often goes unread. Cases usually reach them through people they already know and trust. Our team on the ground makes that introduction, presents your case properly in Chinese, and follows up until you have an answer.
