Ukraine’s lost generation caught in ‘eternal lockdown’

With his shadow of a moustache and baseball cap, Bohdan Levchykov would be your typical teenager anywhere if he didn’t embody the tragedy of what has happened to a generation of young Ukrainians after nearly four years of war.

His father Stanislav, a career soldier, was killed defending the country’s second city Kharkiv just weeks after Russia invaded in 2022. On top of all they have been through, his mother Iryna, 50, was recently diagnosed with stage-three cancer of the uterus.

Bohdan no longer knows anyone his age in his battered hometown of Balakliia, which was occupied by the Russian army from March to September 2022. It was later retaken by Ukrainian forces, but being only 70 kilometres (43 miles) from the front, is still regularly shelled.

“My mother and I came back a few days after the city was liberated, and there were no children left, no shops open, nothing,” he recalled. Only a fraction of the pre-war population of 26,000 have trickled back, and most of them are old.

The skate park and the banks of the Balakliika River where young people used to hang out were mined by the Russians. They have been demined since, “but rumour has it it’s still not safe,” the 15-year-old said.

All Bohdan’s schooling is online, his days punctuated by air raid alerts. The nine flights of stairs down to the basement is more than his sick mother can manage, so they lay a mattress in the small entry to their apartment, the only room without a window. “We’ve gotten used to getting by on our own. We’re a tight team,” Bohdan smiled.

“It’s not just Bohdan. All the children adapted so quickly,” his mother said. “This generation — I don’t know what to make of them…”

She is not the only one to wonder what the war has done to Ukraine’s children.

Nearly a million young Ukrainians are still living in an eternal lockdown, doing either all or part of their lessons online. First there was the pandemic in March 2020, then the invasion — six years of spending most of their time in front of the family computer to study and unwind.

This isolation is particularly felt in the Kharkiv region bordering Russia, which is the target of daily attacks.

A few bars and restaurants stay open until the 11 pm curfew before night brings the inevitable Russian drone and missile attacks. Mornings echo with the sound of volunteer teams repairing whatever can be salvaged.

Some 843 educational establishments have been either destroyed or damaged in the region — a fifth of the national toll, according to the Ukrainian government’s saveschools.in.ua. site.

The online investigative site Bellingcat — with whom AFP journalists in Kyiv and Paris worked on this special report — has logged more than 100 video or photo testimonies on social media of Russian strikes on or close to educational institutions or youth leisure facilities in and around Kharkiv.

Children in tears were evacuated when a city centre daycare was hit on October 22. “We’re going to find your mother right away,” a rescuer told a little girl he was carrying out of the smoke and debris, according to police footage.



– Underground schools –



More and more children are going to underground schools in the city. Yevenhelina Tuturiko has been attending one since September, several metres below the street with no natural light.

“I really love it,” the lanky 14-year-old said, “because I can talk in person with my classmates again.”

Ironically, Yevenhelina had to cross Europe to “meet most of my current friends” in Kharkiv after being invited on a “respite trip” organised by the city of Lille in northern France to give Ukrainian kids a taste of normality.

Kharkiv will have 10 underground schools open by the end of the year, the city hall said.

Priority is given to classes where most of the children remained in Kharkiv during the heaviest of the fighting at the start of the invasion, when Russian forces pushed into the suburbs of the city. Some 70 percent of the city’s children were evacuated at one time or another, either abroad or to the west of Ukraine.

The children spend only half their school day in the bunkers to make room for others, finishing their classes online.

The school AFP visited was built to nuclear shelter standards, with a heavy armoured door. “We are probably one of the safest shelters in all of Ukraine,” its principal Natalia Teplova said proudly.



– ‘Children going mad’ –



All outdoor school sports are banned in the Kharkiv region for fear of Russian strikes. But outside school it’s a little more hazy.

“Official competitions are banned, but we’re not state-run, so we make do on our own,” said football coach and former soldier Oleksandr Andrushchenko as he roared on his young players.

The handful of well-wrapped up parents on the sidelines “understand that their children haven’t developed at all (athletically) since the Covid years. And that it’s better for them to play football… than stay glued to their phones,” he said.

Inside Kharkiv’s largest swimming pool complex, educator Ayuna Morozova agrees: “You can’t live in constant fear.”

The huge Soviet-era brutalist building shut after being hit in two heavy strikes in March 2022, then reopened in May 2024. Now when windows are blown out from the shock waves of nearby bombing, they are just boarded up with plywood or plastic.

“Water and swimming cure everything,” Morozova firmly believes. “First two years of Covid, then four years of war — children are going mad,” she said. The complex is now also home to a water therapy space for amputee soldiers.

With her flame-red hair and warm manner, Ayuna lives up to her Tatar-origin first name, which means “Great Bear”. But like almost everyone AFP met, the wounds of war surface quickly. She was buried under rubble after an airstrike on a public building in 2022. “I still have nightmares,” she said. “I avoid confined spaces and lifts. And yes, I did see a psychologist.”

Ukraine lacks the resources to measure the war’s impact on the young.

“We don’t have enough psychologists,” admitted Oksana Zbitneva, head of the government’s coordination centre for mental health. To try to make up for that, “130,000 frontline health professionals — nurses, paediatricians, family doctors — have received World Health Organization-certified training in mental health,” she said.

While “some countries have been building their (mental health) systems for 50 years, we were the last to get started because of our Soviet legacy,” she added.

The government has opened 326 “resilience centres” for children and parents across the country, and “300 more” should be built next year, according to Social Affairs Minister Denys Ulyutyn.



– Self-harm –



When AFP met psychologist Maryna Dudnyk amid the sunflower fields of Khorosheve, 15 kilometres south of Kharkiv, she had just led three hours of play workshops with around 50 children aged six to 11 to help them express their feelings.

As her team packed away the bulletproof vests — security protocol demands they bring them — she said “the war has had a huge impact on the emotional state of young people, we all live under stress.”

In her consulting room, she hears “a lot of fear and anxiety in children… Teenagers suffer from self-harm, from suicidal thoughts.”

Dudnyk, 50, who works for the Ukrainian NGO “Voices of Children”, also carries her own wounds — fleeing from her hometown Mariupol, which was occupied by the Russian army after a brutal siege. “We no longer have a home, nothing. Everything was destroyed.”

Some teenagers have grown a kind of emotional armour. Illia Issaiev hated it when his family fled the fighting by crossing over into Russia. The months they spent there before returning made him even more of a Ukrainian nationalist.

The lean 18-year-old with steel-blue eyes claims to be a Kharkiv leader of the ultra-nationalist group Prav Molod (“The Right Youth”).

We met him as he trained a group of young men in handling military drones, his speciality. “Hard times make people stronger. Our era is producing strong people who will build a good country,” he declared.

It’s not so simple for Kostiantyn Kosik, who is on medication for his tics, faintness and migraines. “I’m constantly nervous, on edge. It’s because of the war. It has a huge effect on my health,” said the bearded 18-year-old, who was dressed in black.

Kostiantyn is from the Donetsk region, which has been ravaged by fighting since a Russia-backed separatist revolt in 2014. He grew up in Avdiivka, a martyr city now in ruins which fell under Russian control after months of grinding battles.

“I have known war since the age of six. At first it was very interesting for a little boy — the tanks, soldiers, automatic weapons. When I was old enough to understand, it became much less fun,” he said.

He spent weeks sheltering in the basement of his house as it was rattled by explosions, all the neighbours gone.

“In one way it toughened me. But I would have preferred a normal childhood, with friends, with joy,” he said, his room decorated with a large painting of his hometown.



– ‘They continue to dream’ –



Like most of the nearly four million displaced people within Ukraine, Kostiantyn’s family are just about hanging on. They rent a house with no heating in Irpin near Kyiv. Kostiantyn’s mother spends her days caring for his bedridden stepfather who has had a series of heart attacks linked to the conflict.

Kostiantyn is proud to be studying international law at Irpin University and — despite his broken English — wants to be able to work “protecting human rights, in Ukraine and elsewhere in the world”.

Researchers for the WHO who questioned 24,000 young Ukrainians from 11 to 17 at the end of 2023 found a “deterioration in the psychological wellbeing” and “significant” decrease in the happiness they felt.

But there was also a “fairly high level of resilience… to wartime adversity”.

So much so that a UNICEF study in August reported that exams were more a source of stress to them than air raid sirens, which “worryingly suggest that war has become part of everyday life for many children.”

“Children have lost their parents, their friends and are sleeping in air raid shelters,” said Social Affairs Minister Ulyutyn. “And yet they continue to live, to dream.”

When Bohdan, the teenager from Balakliia, is not drawing he plays and chats with his “new friends”, all online. He spends a lot of time chatting with a girl called Lana, with whom “he has many things in common”.

Bohdan also has a dream. “I really want to meet up with Lana. I talked to my mother about it. Maybe our parents can arrange something.” But Lana lives in Dnipro, more than 400 kilometres to the southeast, another world in wartime Ukraine.

In the meantime, Balakliia suffered another strike that killed three people on November 17, 300 metres from Bohdan’s building.

Whether you’re reaching for a mug, a pencil or someone’s hand, you don’t need to consciously instruct each of your fingers on where they need to go to get a proper grip.

The loss of that intrinsic ability is one of the many challenges people with prosthetic arms and hands face. Even with the most advanced robotic prostheses, these everyday activities come with an added cognitive burden as users purposefully open and close their fingers around a target.

Researchers at the University of Utah are now using artificial intelligence to solve this problem. By integrating proximity and pressure sensors into a commercial bionic hand, and then training an artificial neural network on grasping postures, the researchers developed an autonomous approach that is more like the natural, intuitive way we grip objects. When working in tandem with the artificial intelligence, study participants demonstrated greater grip security, greater grip precision and less mental effort.

Critically, the participants were able to perform numerous everyday tasks, such as picking up small objects and raising a cup, using different gripping styles, all without extensive training or practice.

The study was led by engineering professor Jacob A. George and Marshall Trout, a postdoctoral researcher in the Utah NeuroRobotics Lab, and appears Tuesday in the journal Nature Communications.

“As lifelike as bionic arms are becoming, controlling them is still not easy or intuitive,” Trout said. “Nearly half of all users will abandon their prosthesis, often citing their poor controls and cognitive burden.”

One problem is that most commercial bionic arms and hands have no way of replicating the sense of touch that normally gives us intuitive, reflexive ways of grasping objects. Dexterity is not simply a matter of sensory feedback, however. We also have subconscious models in our brains that simulate and anticipate hand-object interactions; a “smart” hand would also need to learn these automatic responses over time.

The Utah researchers addressed the first problem by outfitting an artificial hand, manufactured by TASKA Prosthetics, with custom fingertips. In addition to detecting pressure, these fingertips were equipped with optical proximity sensors designed to replicate the finest sense of touch. The fingers could detect an effectively weightless cotton ball being dropped on them, for example.

For the second problem, they trained an artificial neural network model on the proximity data so that the fingers would naturally move to the exact distance necessary to form a perfect grasp of the object. Because each finger has its own sensor and can “see” in front of it, each digit works in parallel to form a perfect, stable grasp across any object.

But one problem still remained. What if the user didn’t intend to grasp the object in that exact manner? What if, for example, they wanted to open their hand to drop the object? To address this final piece of the puzzle, the researchers created a bioinspired approach that involves sharing control between the user and the AI agent. The success of the approach relied on finding the right balance between human and machine control.

"What we don’t want is the user fighting the machine for control. In contrast, here the machine improved the precision of the user while also making the tasks easier,” Trout said. “In essence, the machine augmented their natural control so that they could complete tasks without having to think about them."

The researchers also conducted studies with four participants whose amputations fall between the elbow and wrist. In addition to improved performance on standardized tasks, they also attempted multiple everyday activities that required fine motor control. Simple tasks, like drinking from a plastic cup, can be incredibly difficult for an amputee; squeeze too soft and you’ll drop it, but squeeze too hard and you’ll break it.

“By adding some artificial intelligence, we were able to offload this aspect of grasping to the prosthesis itself,” George said. “The end result is more intuitive and more dexterous control, which allows simple tasks to be simple again.”

George is the Solzbacher-Chen Endowed Professor in the John and Marcia Price College of Engineering’s Department of Electrical & Computer Engineering and the Spencer Fox Eccles School of Medicine’s Department of Physical Medicine and Rehabilitation.

 

This work is part of the Utah NeuroRobotics Lab’s larger vision to improve the quality of life for amputees.

 

"The study team is also exploring implanted neural interfaces that allow individuals to control prostheses with their mind and even get a sense of touch coming back from this,” George said. “Next steps, the team plans to blend these technologies, so that their enhanced sensors can improve tactile function and the intelligent prosthesis can blend seamlessly with thought-based control."

#####

The study was published online Dec.9 in Nature Communications under the title “Shared human-machine control of an intelligent bionic hand improves grasping and decreases cognitive burden for transradial amputees.”

Coauthors include NeuroRobotics Lab members Fredi Mino, Connor Olsen and Taylor Hansen, as well as Masaru Teramoto, research assistant professor in the School of Medicine’s Division of Physical Medicine & Rehabilitation, David Warren, research associate professor emeritus in the Department of Biomedical Engineering, and Jacob Segil of the University of Colorado Boulder. Funding came from the National Institutes of Health and National Science Foundation.


The Utah researchers outfitted a commercial prosthetic hand with custom fingertips that detect pressure. These fingertips also were equipped with optical proximity sensors capable of “seeing” objects before they made contact with the hand. These sensors allow the AI to assist the user with the fine movements that are critical to dexterous grasping and holding.

VR headsets take war-scarred children to world away from Gaza

Al-Zawayda (Palestinian Territories) (AFP) – Children scarred by the war in Gaza are undergoing a therapy programme using virtual reality headsets that transport the youngsters to a world far away from the destruction around them.

The VR therapy is aimed at improving the children's psychological wellbeing, with operators saying it can achieve results more quickly than traditional therapy sessions.

Inside a white tent pitched on a sandy patch of ground in Al-Zawayda, in central Gaza, excited chatter swelled as five boys roamed around a virtual world.

The youngsters, one in a wheelchair and the others on plastic seats, turned their heads, exploring the new surroundings inside their goggles: a land of green gardens, tranquil beaches and safe cities.

One boy reached out and clapped his hands together, as if swatting a fly. Another, smiling, with his hand held up in front of his face, reached out to touch the scenery.

One said a dog was running towards him, and beckoned to it, calling out: "Come! Come!"

"I see birds," the boy in the wheelchair told an operator, looking around.

One of the operators delicately put the blue TechMed Gaza headset on 15-year-old Salah Abu Rukab, who sustained a head injury during the war, asking if he could see the VR properly as he adjusted the buckles.

"We feel comfortable in it, we enjoy it, and through it we enter a garden, we enter spaces with animals and similar experiences," the teenager told AFP.

Asked by the operator what he saw, he replied: "It's all trees. Nothing but trees, grass and flowers."

'Positive results'

Mental health supervisor Abdalla Abu Shamale explained there was more to the VR headsets than simply escape.

"Through programmers, we are able to design games with therapeutic, preventive and developmental goals that help prepare the child or enable them to cope and manage their life more effectively," he told AFP.

"This method has proven its effectiveness over a full year of working with many children, including war-amputee children, injured children and those exposed to extremely traumatic events."

A fragile ceasefire in the war between Israel and the Palestinian militant group Hamas has held since October 10.

The World Health Organization says conflict-related injuries carry a mental health toll, and survivors struggle with trauma, loss and daily survival, while psychosocial services remain scarce in Gaza.

Jonathan Crickx, spokesman for the UN children's agency UNICEF, told AFP that around one million children, or in other words, "all children in the Gaza Strip, are in need of mental health and psychosocial support after two years of horrendous war".

The VR sessions rely on programmes specifically designed for traumatised children, taking into account their physical and psychological condition, and help them rebuild positive perceptions of the world.

Abu Shamale said the children were "treated and accompanied through VR sessions, and when we integrated them into these techniques, they showed a very, very strong response and extremely positive results.

"The speed of treatment, recovery and reaching stability using VR techniques was faster than in regular sessions. In regular sessions without VR, we usually need about 10 to 12 sessions, while with VR we can achieve results in just five to seven sessions," he said.

New method for intentional control of bionic prostheses



Researchers decode nerve signals for targeted movement control for the first time




Medical University of Vienna





Despite enormous progress in the past two decades, the intentional control of bionic prostheses remains a challenge and the subject of intensive research. Now, scientists at the Medical University of Vienna and Imperial College London have developed a new method for precisely detecting the nerve signals remaining after an arm amputation and utilising them to control an artificial arm. The study results, published in the journal Nature Biomedical Engineering, could form the basis for the development of the next generation of prostheses.

As part of the Natural BionicS project funded by the European Research Council, novel (40-channel) microelectrodes were implanted in the muscles of three arm amputee study participants, which had previously been reconnected to nerves through a process known as targeted muscle reinnervation (TMR). This surgical procedure redirects nerve pathways remaining after amputation to muscles that are still present, thus creating new interfaces through which neural signals can be retrieved.
 
By combining surgical reinnervation with implantable microelectrodes, scientists at MedUni Vienna and Imperial College London succeeded for the first time in directly measuring the activity of individual motor neurons – the nerve cells in the spinal cord that transmit movement commands to the muscles – and linking their signal patterns to specific movement intentions. To achieve this result, the participants mentally performed various movements with their phantom arm. "Using our method, we were able to precisely identify the nerve signals that underlie, for example, the stretching of a finger or the bending of the wrist," reports study author Oskar Aszmann, head of the Clinical Laboratory for Bionic Limb Reconstruction at the Department of Plastic, Reconstructive and Aesthetic Surgery at MedUni Vienna.

Foundation for the development of wireless implants
Analysis of the recorded, highly differentiated nerve signals also showed that complex movement intentions remain intact in the nervous system even after amputation and can be mathematically reconstructed. This means that this information can be used in future for the precise control of bionic prostheses. "This is a crucial step towards making the control of bionic limbs more natural and intuitive," says Oskar Aszmann, emphasising the relevance of the study results.

In the long term, these findings will lead to the development of a so-called bioscreen – a system that visualises the complex neural patterns of human movements and thus forms the basis for new generations of prostheses. Current research is thus laying the foundation for the development of wireless implants that can transmit nerve signals directly and in real time to bionic hands or other assistance systems.

Genoa (Italy), 30 October 2025: One year after the international Cybathlon 2024 competition, the Italian team has published a focus article in Science Robotics on the Omnia bionic leg, which took first place in the leg prosthesis race. The article highlights the experience of Andrea Modica, a transfemoral amputee and the device’s pilot, who successfully completed 9 out of 10 tasks in 2 minutes and 57 seconds. The Omnia prosthesis was developed at the Istituto Italiano di Tecnologia (IIT – Italian Institute of Technology) by the joint Rehab Technologies IIT-INAIL Lab, coordinated by Matteo Laffranchi.

The Cybathlon 2024 marked the debut of Omnia, a novel lower limb prosthetic prototype designed for individuals with transfemoral amputations. This system comprises a knee (Unico) and an ankle (Armonico), both motorized. Omnia was the only device to reach the "Leg Prosthesis" final without using commercial components. Its pilot, Andrea Modica, successfully completed 9 out of 10 tasks, including navigating a balance beam while carrying buckets, ascending and descending stairs with objects, and traversing an inclined plane.

Andrea Modica is a transfemoral amputee who lost his leg in a motorcycle accident in 2021. Since then, Modica has shown remarkable determination, first returning to sports, then progressing to Paralympic-level skiing, and stepping into the world of competitive prosthetic technology. He is currently Support Technician at Rehab Technologies - INAIL-IIT lab.

Modica was not only the pilot for the Omnia system but also an active contributor to its design and optimization. His insights, gained by comparing Omnia with his daily-use prosthesis, helped the research team to shape key improvements in both the software and hardware of the device. From adjusting stiffness to fine-tuning propulsion, each component was tailored to match the varied demands of the Cybathlon’s obstacle-based tasks. During months of training, Modica repeatedly practiced each task to improve precision, efficiency, and safety.

Reflecting on the event, Andrea Modica described it as a deeply meaningful experience, not just for the achievement, but for the community he found among other competitors. His role in shaping Omnia exemplifies IIT’s user-centered philosophy, where real-world feedback drives innovation.

The standout feature of the Omnia system is the communication between the two prosthetic components, Unico and Armonico, which exchange information from integrated sensors and adjust parameters for optimal performance across various tasks. The Unico knee combines hydraulic and electric technologies. The hydraulic system effectively aids in level walking or descending, ensuring quiet, smooth movement and energy efficiency. In contrast, the electric technology, supported by a patented system, provides active assistance during tasks such as climbing stairs, ascending steep slopes, or standing from a seated position. In the complete Omnia leg configuration, the transition between hydraulic and electric modes occurs automatically, thanks to the synergy of the two prostheses and advanced implemented algorithms.

The Unico prosthesis is equipped with a battery that lasts a full day under maximum usage and is suitable for both right and left knee prosthetics, supporting up to 125 kilograms. The device is customizable based on the user's height and can be adjusted at the software level to match daily activity patterns, whether sedentary or active.

The Armonico ankle features an elastic foot coupled with an innovative screw mechanism, assisting the user during the initial foot strike by reducing heel impact for enhanced comfort and preventing tripping by lifting the toe during each step. Unlike passive foot prostheses, Armonico actively amplifies the ankle’s flexion angle, providing enhanced stability on sloped surfaces and ensuring a more natural movement. It is available in both right and left configurations and has a battery life of 24 hours.
