Paralysed man walks again thanks to ‘digital bridge’ that wirelessly reconnects brain and spinal cord
A paralysed man has been able to walk again after communication was re-established between his brain and spinal cord using a wireless “digital bridge”.
The so-called brain computer interface is made up of two electronic implants, one each in the brain and spinal cord.
The former is placed above the region of the brain responsible for controlling leg movements, and can decode the electrical signals generated when we think about walking.
Similarly, the other implant is positioned over the part of the spinal cord that controls the legs.
Working together, scientists say the groundbreaking technology “transforms thought into action” – repairing the broken connection between the brain and the region of the spinal cord that controls movement.
The first patient was a 40-year-old man, Gert-Jan, who suffered a spinal cord injury in a bike accident in 2011.
It had left him paralysed, but he noticed improvements within days of surgeons calibrating the implants.
Rediscovering simple pleasures
“The most surprising thing I think happened after two days,” Gert-Jan said.
“Within five to minutes, I could control my hips.”
Since then, after “a long journey” of training, the patient has been able to walk, climb stairs and navigate ramps.
He has also rediscovered the “simple pleasure” of standing with friends at a bar.
The implants remained effective after a year, including when Gert-Jan was unsupervised at home.
He was treated by neuroscientists and neurosurgeons from Switzerland’s Lausanne University Hospital and the University of Lausanne, and the Swiss Federal Institute of Technology Lausanne.
The implants themselves were developed by the French Atomic Energy Commission.

How does the technology work?
Guillaume Charvet, head of the project at the commission, said the implants use “adaptive artificial intelligence” to decode movement intentions from the brain in real time.
Once AI identifies the relevant signals, they are converted into sequences of electrical stimulation for the spinal cord, which activate the leg muscles and prompt the desired movement.
Remarkably, the patient experienced improvements in his sensory perceptions and motor skills that were maintained even when the digital bridge was switched off – allowing him to walk with crutches.
Professor Gregoire Courtine said this suggests the digital bridge not only repaired the man’s spinal cord, but also “promotes the growth of new nerve connections”.
Gert-Jan is the only patient who the digital bridge has been tested on, but it is hoped the technology could be used to restore arm and hand functions in future.
It could also be applied following other causes of paralysis, such as a stroke.
The findings have been detailed in the journal Nature.
The Syrian presidency has announced it’s assembling a special taskforce to try to stop nearly a week of sectarian clashes in the southern Druze city of Sweida.
The presidency called for restraint on all sides and said it is making strenuous efforts to “stop the fighting and curb the violations that threaten the security of the citizens and the safety of society”.
By early Saturday morning, a ceasefire had been confirmed by the US special envoy for Syria, Tom Barrack, who posted on X that Syrian President Ahmed al Sharaa and Israeli Prime Minister Benjamin Netanyahu had agreed to a ceasefire supported by US secretary of state Marco Rubio.
The post went on to state that this agreement had the support of “Turkey, Jordan and its neighbours” and called upon the Druze, Bedouins, and Sunni factions to put down their arms.
Sky News special correspondent Alex Crawford reports from the road leading to Sweida, the city that has become the epicentre of Syria’s sectarian violence.
For the past 24 hours, we’ve watched as Syria‘s multiple Arab tribes began mobilising in the Sweida province to help defend their Bedouin brethren.
Thousands travelled from multiple different Syrian areas and had reached the edge of Sweida city by Friday nightfall after a day of almost non-stop violent clashes and killings.
“We have come to protect the [Arab] Bedouin women and children who are being terrorised by the Druze,” they told us.

Every shop and every home in the streets leading up to Sweida city has been burned or ransacked, the contents destroyed or looted.
We saw tribal fighters loading the back of pickup trucks and driving away from the city with vehicles packed with looted goods from Druze homes.

Several videos posted online showed violence against the Druze, including one where tribal fighters force three men to throw themselves off a high-rise balcony and are seen being shot as they do so.
Doctors at the nearby community hospital in Buser al Harir said there had been a constant stream of casualties being brought in. As we watched, another dead fighter was carried out of an ambulance.
The medics estimated there had been more than 600 dead in their area alone. “The youngest child who was killed was a one-and-a-half-year-old baby,” one doctor told us.

The violence is the most dangerous outbreak of sectarian clashes since the fall of the Bashar al Assad regime last December – and the most serious challenge for the new leader to navigate.
The newly brokered deal is aimed at ending the sectarian killings and restoring some sort of stability in a country which is emerging from more than a decade of civil war.
Israel and Syria have agreed to a ceasefire, the US ambassador to Turkey has said.
Several hundred people have reportedly been killed this week in the south of Syria in violence involving local fighters, government authorities and Bedouin tribes.
As the violence escalated in the southern province of Sweida, Israel launched airstrikes, including attacks on Wednesday on the defence ministry in Damascus and a target near the presidential palace.
Israeli Prime Minister Benjamin Netanyahu’s government said it aimed to protect Syrian Druze – part of a small but influential minority that also has followers in Lebanon and Israel.
In a post on X, the US ambassador to Turkey, Tom Barrack, said Israel and Syria had agreed to a ceasefire supported by Turkey, Jordan and others.
“We call upon Druze, Bedouins, and Sunnis to put down their weapons and together with other minorities build a new and united Syrian identity,” Mr Barrack said in a post on X.
The Israeli embassy in Washington and Syrian Consulate in Canada did not immediately comment or respond to requests for comment from the Reuters news agency.
The ceasefire announcement came after the US worked to put an end to the conflict, with secretary of state Marco Rubio saying on Wednesday that steps had been agreed to end a “troubling and horrifying situation”.

Why is Israel bombing Syria?
After Israel warned it would destroy forces attacking Syrian Druze, Syrian President Ahmed al Sharaa told the minority group in a televised statement on Thursday that “we reject any attempt to drag you into hands of an external party”.
He then claimed Israel has “consistently targeted our stability and created discord among us since the fall of the former regime”.
It comes after the United Nations’ migration agency said earlier on Friday that nearly 80,000 people had been displaced in the region since violence broke out on Sunday.
It also said that essential services, including water and electricity, had collapsed in Sweida, telecommunications systems were widely disrupted, and health facilities in Sweida and Daraa were under severe strain.

Attorney general Pam Bondi wrote on X: “I just spoke to @USAttyEssayli about what appears to be a horrific incident that killed at least three at a law enforcement training facility in Los Angeles.
“Our federal agents are at the scene and we are working to learn more.”
California congressman Jimmy Sanchez said the explosion had “claimed the lives of at least three deputies”.
“My condolences to the families and everyone impacted by this loss,” he said.
