A man paralysed by a spinal cord injury has walked again after scientists created a “digital bridge” restoring communication between his brain and spine.
Using crutches, Dutchman Gert-Jan Oskam, 40, can stand, walk, navigate ramps and even climb stairs, science journal Nature reported on Thursday.
Mr Oskam said he is able to walk at least 100m or more on some days.
He is also able to walk on crutches when the implant is switched off, raising hope that technologies such as these could restore lost nerve function.
“I feel like a toddler, learning to walk again,” Mr Oskam told the BBC.
“It has been a long journey, but now I can stand up and have a beer with my friend. It's a pleasure that many people don't realise.”
Mr Oskam was paralysed in a biking accident 11 years ago that caused an incomplete spinal cord injury.
Five years later, a clinical trial involving a spinal cord implant restored Mr Oskam’s ability to take steps when aided with a walker.
He could walk but only over flat surfaces, and had difficulty starting and stopping.
The aim of the study, by a team including Gregoire Courtine, a neuroscientist at the Swiss Federal Institute of Technology in Lausanne, was to hand control to Mr Oskam’s brain.
“Despite using the [spinal cord implant] stimulation for three years, he hit a plateau in his recovery, and became interested in using the new brain-controlled stimulation,” Dr Courtine said.
“So, he became our first test pilot.”
'Encouraging' results
To walk, the brain delivers executive commands to the neurons in the lumbosacral spinal cord.
Damage to these neurons can interrupt brain commands that are necessary to walk. The result is permanent paralysis.
But scientists created the bridge between the brain and spinal cord to enable control over the timing and volume of muscle activity, restoring control of standing and walking in people paralysed by a spinal cord injury.
Once the patient’s brain activity was decoded, the brain-spine interface took a few minutes to calibrate. Soon the man reported natural-feeling control over movements.
A study published in Nature in 2022 showed that stimulating spinal cord nerves could produce some movement.
But the latest study is the first time that a patient’s own brain activity has been used to restore voluntary control of leg movements.
Dr Courtine and colleagues analysed Mr Oskam’s brain activity while he attempted leg movements. They found patterns of activity were different when he attempted hip, knee and ankle movements.
The team reproduced a walking motion using stimulation patterns aimed at muscles that control putting weight down, pushing forward and leg swings.
An artificial intelligence algorithm translates incoming brain signals into appropriate command signals for the spinal implant.
Mr Oskam underwent two operations to implant electrodes in the brain and the spinal cord to make the digital bridge.
The technology uses artificial intelligence to convert movement thoughts into actions, establishing a direct link between the brain and spinal cord regions involved in walking.
Dr Courtine said: “For the first time this digital bridge bypasses an injury, restoring the communication between two regions of the central nervous system that are disconnected.
"What we observed is a digital repair of the spine, a recovery of neurological function that he has lost for many years."
Physiologist V Reggie Edgerton of California’s Rancho Los Amigos National Rehabilitation Centre, told Science News: "The results are consistent with what I’d hope would happen, which is encouraging.”
Mr Edgerton, who was not involved in the study, said in terms of treating spinal cord paralysis, “we’re at the stage of the Wright brothers and flight”.

Four reasons global stock markets are falling right now
There are many factors worrying investors right now and triggering a rush out of stock markets. Here are four of the biggest:
1. Rising US interest rates
The US Federal Reserve has increased interest rates three times this year in a bid to prevent its buoyant economy from overheating. They now stand at between 2 and 2.25 per cent and markets are pencilling in three more rises next year.
Kim Catechis, manager of the Legg Mason Martin Currie Global Emerging Markets Fund, says US inflation is rising and the Fed will continue to raise rates in 2019. “With inflationary pressures growing, an increasing number of corporates are guiding profitability expectations downwards for 2018 and 2019, citing the negative impact of rising costs.”
At the same time as rates are rising, central bankers in the US and Europe have been ending quantitative easing, bringing the era of cheap money to an end.
2. Stronger dollar
High US rates have driven up the value of the dollar and bond yields, and this is putting pressure on emerging market countries that took advantage of low interest rates to run up trillions in dollar-denominated debt. They have also suffered capital outflows as international investors have switched to the US, driving markets lower. Omar Negyal, portfolio manager of the JP Morgan Global Emerging Markets Income Trust, says this looks like a buying opportunity. “Despite short-term volatility we remain positive about long-term prospects and profitability for emerging markets.”
3. Global trade war
Ritu Vohora, investment director at fund manager M&G, says markets fear that US President Donald Trump’s spat with China will escalate into a full-blown global trade war, with both sides suffering. “The US economy is robust enough to absorb higher input costs now, but this may not be the case as tariffs escalate. However, with a host of factors hitting investor sentiment, this is becoming a stock picker’s market.”
4. Eurozone uncertainty
Europe faces two challenges right now in the shape of Brexit and the new populist government in eurozone member Italy.
Chris Beauchamp, chief market analyst at IG, which has offices in Dubai, says the stand-off between between Rome and Brussels threatens to become much more serious. "As with Brexit, neither side appears willing to step back from the edge, threatening more trouble down the line.”
The European economy may also be slowing, Mr Beauchamp warns. “A four-year low in eurozone manufacturing confidence highlights the fact that producers see a bumpy road ahead, with US-EU trade talks remaining a major question-mark for exporters.”
Banned items
Dubai Police has also issued a list of banned items at the ground on Sunday. These include:
-
-
-
-
-
-
-
-
-
Political flags or banners
-
Bikes, skateboards or scooters
