A young paralyzed man just walked again after having an electrode implanted in his back.

Doctors at the Mayo Clinic in Minnesota have helped a paralyzed man walk 100 yards with the aid of a walker after implanting a remote-controlled electrode in his back.

Jered Chinnock, 29, was paralyzed five years ago after a devastating snowmobile accident left him with no movement or sensation below his mid-back. But after 43 weeks of intense rehab, and the help of the electrode, he was able to walk again.

Researchers at the Mayo Clinic implanted a battery in his abdomen to power the spinal-nerve stimulating electrode.


If the electrode is turned off or loses power, Chinnock can no longer stand.

“The walking side of it isn’t something where I just leave my wheelchair behind and away I go,” Chinnock, of Tomah, Wisconsin, told The Associated Press. But, “there is the hopeful side of, maybe I’ll gain that — where I can leave the wheelchair behind, even if it is to walk to the refrigerator.”

After 25 weeks of therapy Chinnock was able to take his first steps without a harness and since, he has walked over 100 yards and done so continuously for as long as 16 minutes.

“The reason why this is important is because the patient’s own mind, thought, was able to drive movement in his legs,” Dr Kendall Lee, who co-led the Mayo Clinic team, told The Independent. “Just as important is that we were able to get him to stand independently and take his own steps.”

While the study's initial results are promising, researchers need to dig deeper to uncover the specific reasons for their success.

“Now I think the real challenge starts, and that's understanding how this happened, why it happened, and which patients will respond,” said co-principal investigator Dr Kristin Zhao, director of the Mayo Clinic's Assistive and Restorative Technology Laboratory.

Researchers theorize that the electrical currents awaken nerve circuits beneath the injury which are droment, but living. The electric currents, paired with rigorous rehab, enable the nerve circuits to receive simple commands from the brain.

“To be able to move my legs and even to stand, it means a lot,” Chinnock told The Huffington Post. “That there’s hope for not only me, but other people.”

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.

Researchers at Harvard University have studied the connection between spanking and kids' brain development for the first time, and their findings echo what studies have indicated for years: Spanking isn't good for children.

Comments on this article will no doubt be filled with people who a) say they were spanked and "turned out fine" or b) say that the reason kids are [fill in the blank with some societal ill] these days are because they aren't spanked. However, a growing body of research points to spanking creating more problems than it solves.

"We know that children whose families use corporal punishment are more likely to develop anxiety, depression, behavior problems, and other mental health problems, but many people don't think about spanking as a form of violence," said Katie A. McLaughlin, director of the Stress & Development Lab in the Department of Psychology, and the senior researcher on the study which was published Friday in the journal Child Development. "In this study, we wanted to examine whether there was an impact of spanking at a neurobiological level, in terms of how the brain is developing."

You can read the entire study here, but the gist is that kids' brain activity was measured using an MRI machine as they reacted to photos of actors displaying "fearful" and "neutral" faces. What researchers found was that kids who had been spanked had similar brain neural responses to fearful faces as kids who had been abused.

"There were no regions of the brain where activation to fearful relative to neutral faces differed between children who were abused and children who were spanked," the authors wrote in a statement.
