Advances in Exoskeleton Technology Could Help Some Walk Again

An accident, a stroke, or a disease can leave someone paralyzed and unable to walk. That happens to more than 15 million people around the world each year.

But new technological advances and physical therapy could help some of them walk again.  

Among the most promising is the use of robotic exoskeletons, like one made by Ekso Bionics. It looks a bit like a backpack that straps on the user’s back and around the midsection. Robotic ‘legs’ complete with foot panels extend from either side of the pack and wrap around the patient’s legs. A video game-style controller attaches to the pack with a long cord.

“I’m going to be a robot!”

Lindsey Stoefen has been doing physical therapy with the exoskeleton for an hour a day, as she works to recover from the rare disorder that put her in a wheelchair in October.

The 17-year-old athlete climbed into a specially designed exoskeleton for the first time in late April, after becoming an in-patient at Marianjoy Rehabilitation Hospital in Chicago.

She recalls being nervous. “I was like ‘Dang, I’m going to be a robot!’ I was scared at first.  I was like, ‘Am I going to like it?  Will I be okay?’  And once I got into it, I loved it.”

Lauren Bularzik, Lindsey’s physical therapist, says the exo robots help to accelerate the rehabilitation process. “For someone who takes a lot of energy to only walk a few feet, exo can get them up, can get them moving, it can supplement their movements, get that reciprocal pattern, encourage the correct motor planning.”

Beside speeding up recovery times, these robotic skeletons are especially helpful for those with paralysis, from spinal cord injuries and strokes. Using the machine can help some patients rewire their brains to use secondary muscles, so they can eventually walk again – without the device.

The downside

 

Scientists at the University of Notre Dame are leading the way with their work on wearable robots that allow patients to regain some or all of their mobility.  But Patrick Wensing, assistant professor of mechanical engineering, says exoskeletons have one big drawback.

 

“While existing exoskeletons are very powerful, they don’t understand what the user wants to do. So in order to transition between activities in daily life, you often have to press a button interface to tell the exoskeleton ‘I would like to stand up now.’”

 

Wensing and his team are collaborating with Ekso Bionics, a leading developer of wearable robots, to create a machine that can understand what its user wants to do without implanted sensors and complicated control panels.

 

The new three-year project funded by The National Science Foundation’s robotic initiative, hopes to achieve a more fluid, intuitive system.

 

Taylor Gambon has spent the last year analyzing data from exoskeleton users and comparing them to models of everyday walking. “What we’re seeing is that slow walking in general, whether in the exoskeleton or just the human, is much different from walking at a speed that you would choose naturally.”

 

Later this year, the team will travel to Ekso Bionics’ California headquarters, where they will work directly with exoskeletons to design programs that interact with users of various disabilities, so that more people like Lindsey Stoefen can get back on their feet again.

Developing an Intuitive Exoskeleton

Every year more than 15 million people worldwide suffer injuries and illnesses that leave them unable to walk according to the World Health Organization. But new technological advances and physical therapy could help some of them walk again. Among the most promising – is the use of robotic exoskeletons. As Erika Celeste reports, scientists at the University of Notre Dame are leading the way with their work on wearable robots that allow patients to regain some or all of their mobility.

Papua New Guinea Considers Facebook Ban

The government Papua New Guinea is considering blocking Facebook while it investigates how to best to regulate the social networking site. Critics say the move would be authoritarian.

Authorities in Papua New Guinea, or PNG, say Facebook has become a magnet for illegal and unsavory activity. The government is considering a temporary ban on the site while it works out the best way to regulate the social media platform.

Only about 10 percent of the nearly 7 million people in PNG use Facebook, but some officials have become increasingly agitated by content being posted online.They have asked experts to help in their search for the best way to impose controls on the social media site.

PNG Communications Minister, Sam Basil, says illegal use of Facebook must be curbed.

“Defamatory publications or the fake news, identity theft and, of course, unidentified Facebook users. Most of those users are the ones that are really breaching all the laws in terms of posting pornography materials and, of course, posting fake news,” he said.

But critics believe the government’s attempts to muzzle Facebook are an attack on free speech. They believe that ministers are motivated by a desire to silence those who expose official corruption and wrongdoing online.

Lawrence Stephens, the chairman of Transparency International PNG, says a temporary ban of Facebook would be a draconian move.

“To talk about stopping this for a month whilst someone, somewhere does an analysis of what we should be able to see sounds pretty authoritarian and pretty worrying,” said Stephens.

The move to temporarily ban Facebook comes as PNG prepares to host the 2018 Asia Pacific Economic Cooperation, or APEC, leaders’ summit later this year.

PNG is a South Pacific nation and is Australia’s closest neighbor.

Report: UK Food, Fuel, Medicine Short Under ‘No Deal’ Brexit

British civil servants have warned of shortages of food, fuel and medicines within weeks if the U.K. leaves the European Union without a trade deal, a newspaper reported Sunday.

The Sunday Times said government officials have modeled three potential scenarios for a “no deal” Brexit: mild, severe and “Armageddon.”

It said under the “severe” scenario, the English Channel ferry port of Dover would “collapse on day one” and supermarkets and hospitals would soon run short of supplies.

 

Britain wants to strike a deal on future trade relations with the EU before it officially leaves the bloc on March 29, 2019, but officials are also drawing up plans for negotiations ending without an agreement.

 

The U.K.’s Department for Exiting the European Union rejected the downbeat scenario, saying it was drawing up no-deal plans but was confident “none of this would come to pass.”

 

Britain and the EU are aiming to strike an overall Brexit agreement by October, so parliaments in other EU nations have time to ratify it before Britain leaves the bloc.

 

But British Prime Minister Theresa May’s Conservative government is split between ministers who favor a clean-break “hard Brexit,” that would leave Britain freer to strike new trade deals around the world, and those who want to keep the country closely aligned to the EU, Britain’s biggest trading partner.

 

 EU leaders are frustrated with what they see as a lack of firm proposals from the U.K. over how to resolve major issues around customs arrangements and the status of the border between Northern Ireland and the Republic of Ireland. That will be the U.K.’s only land border with the EU after Britain leaves the bloc.

 

Irish Deputy Prime Minister Simon Coveney said Saturday that the U.K. must produce “written proposals” for the border within two weeks, ahead of a June 28-29 EU summit.

 

 British Home Secretary Sajid Javid said Sunday that the British government would have “a good set of proposals” to submit to the bloc at its June meeting.

Professional Cuddling: A New Occupation

A new occupation has emerged in the United States: professional cuddler. While to some the idea might sound strange, scientists from the Miami Touch Research Institute say they are not surprised at the demand for such services. The institute says that’s because the American culture is one of the most touch-averse in the world. Anush Avetisyan has more on this story.

China Warns US: No Trade Deal if Tariffs Go Ahead

China has warned that any agreements with Washington in their talks on settling a sprawling trade dispute “will not take effect” if threatened U.S. sanctions including tariff hikes go ahead.

The statement Sunday came shortly after delegations led by U.S. Commerce Secretary Wilbur Ross and China’s top economic official, Vice Premier Liu He, held another round of talks on China’s pledge to narrow its trade surplus with the United States by purchasing more American goods. 

The Chinese statement said the two sides made “positive and concrete progress,” but neither side released details.

The statement said, “If the United States introduces trade sanctions including increasing tariffs, all the economic and trade achievements negotiated by the two parties will not take effect.”

Ross said U.S. and Chinese officials have discussed specific American export items Beijing might buy as part of its pledge to narrow its trade surplus with the United States.

The two sides began a new round of talks in Beijing this weekend aimed at settling a simmering trade dispute.

Ross gave no details at the start of his meeting Sunday with Liu, China’s top economic official. But Chinese envoys promised after the last high-level meeting in Washington in mid-May to buy more American farm goods and energy products.

President Donald Trump is pressing Beijing to narrow its politically volatile surplus in trade in goods with the United States, which reached a record $375.2 billion last year. He’s threatening to hike duties on up to $150 billion of Chinese imports.

“Our meetings so far have been friendly and frank, and covered some useful topics about specific export items,” Ross said.

Ross was accompanied by agricultural, treasury and trade officials. Liu’s delegation included China’s central bank governor and commerce minister.

There was no indication whether the talks also would take up American complaints that Beijing steals or pressures foreign companies regarding their technology. The White House renewed a threat this week to hike duties on $50 billion of Chinese technology-related goods over that dispute.

Private sector analysts say that while Beijing is willing to compromise on its trade surplus, it will resist changes that might threaten plans to transform China into a global technology competitor.

Ross had a working dinner Saturday evening with Liu, also at the same guesthouse in Beijing.

China has promised to “significantly increase” purchases of farm goods, energy and other products and services. Still, Beijing resisted pressure to commit to a specific target of narrowing its annual surplus with the United States by $200 billion.

China Warns US Tariffs Will Undo Existing Deals

China is warning the United States any trade and business agreements between the two countries will be void if President Donald Trump carries out his threats to impose tariff hikes and other trade measures.

The warning came after U.S. Commerce Secretary Wilbur Ross and Chinese Deputy Prime Minister Liu He ended a new round of talks Sunday in Beijing aimed at settling a simmering trade dispute, in which Beijing pledged to buy more American products to narrow its trade surplus with the United States.  The Chinese trade surplus reached $375 billion last year.

No joint statement was issued and neither side released details.

“Our meetings so far have been friendly and frank,” Ross said at the start of the talks, “and covered some useful topics about specific export items” China might buy.

Chinese envoys had promised after the last high-level meeting in Washington in mid-May to buy more American farm goods and energy products.

Ross was accompanied by agricultural, treasury and trade officials.

 

Liu’s delegation included China’s central bank governor and commerce minister.

There was no indication whether the talks also took up American complaints that Beijing steals from or pressures foreign companies.

Trump is threatening to hike duties on up to $150 billion of Chinese imports, with Beijing vowing to retaliate in kind.

The White House renewed a threat last week to hike duties on $50 billion of Chinese technology-related goods in that dispute.

The state-run Chinese newspaper Global Times contended in an editorial that, “Tariffs and expanding exports – the United States can’t have both.  China-U.S. trade negotiations have to dig up the two sides’ greatest number of common interests, and cannot be tilted toward unilateral U.S. interests.”

While the U.S.-China trade and tariff disputes remain unresolved, Trump last week imposed new tariffs on steel and aluminum imports from the European Union, Canada and Mexico, angering three key U.S. allies who vowed to retaliate by imposing new duties on American goods.

Classical Music from Concert Halls Hits Downtown Streets

Trucks can be used for so much more than transporting goods from one place to another. They can be transformed into restaurants, mobile health clinics … even a concert hall.

That’s what two young pianists have done with their truck as they work to make classical music more accessible to a wider range of audiences.

 

The Concert Truck

 

Nick Luby came up with the idea for the Concert Truck, says his partner, Susan Zhang. “He went sailing with his grandfather,” she says. “When they would dock, they would go to certain churches where he could practice (piano). While he was practicing, people would gather because they were curious about what he was playing.”

Though people can listen to music anywhere, on radio, TV or on their earphones with MP3 players, Luby says nothing is like listening to live music.

“When you listen to live music there is energy they just can’t get from recordings.” He adds, “It brings people together. For me it makes life worth living.”

But for Zhang, the idea of using a truck to bring live music to different locations was a bit unsettling at first.

 

“When he came to me with the idea, I thought he was crazy,” she recalls. “Then, I watched this movie, ‘Chef,’ about a chef who has a food truck and he travels across the country and I thought that kind of life would be so cool, so I decided to go in on this with him.”

The next step was to get funding.

“We started by winning a Creativity in Music Award from our university in South Carolina,” Luby says. “That was matched by the Performing Art Consortium. They provide some financing for artists to perform or to apply for schools and competitions. And the piano is a generous loan from Jordan Kitts Music, which is a piano store in Rockville, Maryland.”

That was two years ago, and they’ve been performing ever since.

A different experience

Zhang admits that performing from a truck, in the middle of street traffic and noise, can be challenging.

 

“Usually when you perform in a concert hall, everything is very controlled, everybody is quiet, the lighting,” she says. “In a place like this, anything could happen. When I start performing, I really don’t notice a lot of the things that happen. I think there is definitely a kind of endurance you gain from performing on a truck.”

And the artists don’t take it personally when people pass by and don’t stay to listen.

“When people walk by and listen for a second and keep going you definitely notice, but the fact that someone stops even for a second or a minute is really a nice thing to be able to share that moment with people,” Luby says.

 

On a recent day, the performance is in front of a farmers market in Baltimore, where Luby and Zhang are both high school music teachers. With their rented piano tightly stored aboard the truck, the duo head downtown. The 5-meter-long Concert Truck is equipped with speakers and lights, and takes only a few minutes to transform into a stage.

The music draws a lunchtime crowd, including Reba Cornman, who was buying some herbs from the farmers market.

“All of a sudden, I heard (Sergei) Prokofiev’s ‘Cinderella’ played on piano,” Cornman says. “I love Prokofiev! I came right over and sit down. It was extraordinary. I know they’re trying to reach all kinds of audiences and being on a truck is such a remarkable way to do that.”

 

Baltimore Farmers Market manager Jill Ciotta worked with Luby and Zhang to bring their Concert Truck to the market. She considers the performing experience part of the healthy focus the market, which is run by the University of Maryland’s Medical Center, tries to promote in downtown.

 

“We’re always open on bringing in things that make it better and bigger and really draw people outside, get moving, walking, and get healthy food. I’d love to see more performances here, I’d love to see them attracting more people, employees, students and neighbors, and getting them to enjoy the outdoors,” Ciotta said.

Performing on the road

The Concert Truck has performed in schools, children’s homes and homeless shelters, in addition to public squares in several cities in South Carolina, Ohio, Maryland and Minnesota. These trips, Luby says, bring him closer to his dream, “to create a platform that allows musicians, not just us but many musicians, to share their craft and their art broadly.”

 

That dream is what keeps Luby and Zhang energized, and on the road, bringing the Concert Truck and classical music to new audiences.
