The Washington Post

A new surgical procedure and neuroprosthetic interface developed by MIT researchers allows people with amputations to control their prosthetic limbs with their brains, “a significant scientific advance that allows for a smoother gait and enhanced ability to navigate obstacles,” reports Lizette Ortega for The Washington Post. “We’re starting to get a glimpse of this glorious future wherein a person can lose a major part of their body, and there’s technology available to reconstruct that aspect of their body to full functionality,” explains Prof. Hugh Herr. 

STAT

Researchers at MIT have developed a novel surgical technique that could “dramatically improve walking for people with below-the-knee amputations and help them better control their prosthetics,” reports Timmy Broderick for STAT. “With our patients, even though their limb is made of titanium and silicone, all these various electromechanical components, the limb feels natural, and it moves naturally, without even conscious thought," explains Prof. Hugh Herr. 

The Economist

Using a new surgical technique, MIT researchers have developed a bionic leg that can be controlled by the body’s own nervous system, reports The Economist. The surgical technique “involved stitching together the ends of two sets of leg muscles in the remaining part of the participants’ legs,” explains The Economist. “Each of these new connections forms a so-called agonist-antagonist myoneural interface, or AMI. This in effect replicates the mechanisms necessary for movement as well as the perception of the limb’s position in space. Traditional amputations, in contrast, create no such pairings.”  

Financial Times

A new surgical approach developed by MIT researchers enables a bionic leg driven by the body’s nervous system to restore a natural walking gait more effectively than other prosthetic limbs, reports Clive Cookson for the Financial Times. “The approach we’re taking is trying to comprehensively connect the brain of the human to the electro-mechanics,” explains Prof. Hugh Herr.  

The Boston Globe

Researchers at MIT and Brigham and Women’s Hospital have created a new surgical technique and neuroprosthetic interface for amputees that allows a natural walking gait driven by the body’s own nervous system, reports Adam Piore for The Boston Globe. “We found a marked improvement in each patient’s ability to walk at normal levels of speed, to maneuver obstacles, as well as to walk up and down steps and slopes," explains Prof. Hugh Herr. “I feel like I have my leg — like my leg hasn’t been amputated,” shares Amy Pietrafitta, a participant in the clinical trial testing the new approach.

The Guardian

MIT scientists have conducted a trial of a brain controlled bionic limb that improves gait, stability and speed over a traditional prosthetic, reports Hannah Devlin for The Guardian. Prof. Hugh Herr says with natural leg connections preserved, patients are more likely to feel the prosthetic as a natural part of their body. “When the person can directly control and feel the movement of the prosthesis it becomes truly part of the person’s anatomy,” Herr explains. 

BBC News

Prof. Hugh Herr joins the BBC’s Shiona McCallum to discuss a program by the K. Lisa Yang Center for Bionics aimed at bringing prosthetics to those who suffered forced amputations during the Sierra Leone Civil War. “When we train a young person on how to construct an arm or leg prothesis we’ve impacted the country for solidly forty years,” Herr says. “That person’s going to be living in that country and contributing to their community for a very long time. That’s exciting.” 

Correio Braziliense

Reporting in Portuguese, Correio Braziliense highlights researchers at MIT who have developed a new technique that uses light stimuli to benefit people with paralysis or amputations. “Our work could help bring the use of optogenetics closer to humans in the realm of neuroprosthetics that control paralyzed muscles and other functions of the peripheral nervous system,” says graduate student Guillermo Herrera-Arcos. 

WHDH 7

MIT researchers have developed a new magnet-based system to monitor muscle movements that could help make prosthetic limbs easier to control, reports Brianna Silva for WHDH.

NPR

David Moinina Sengeh MS ’12, PhD ’15 speaks with Ted Radio Hour host Manoush Zomorodi about his research in developing a more comfortable socket for prostheses. Sengeh “pioneered a new system for creating prosthetic sockets, which fit a prosthetic leg onto a patient's residual limb,” writes NPR.

The Wall Street Journal

Wall Street Journal reporter John Anderson spotlights “Augmented” a new PBS documentary featuring Prof. Hugh Herr and his work in robotic limbs and surgery.

The Boston Globe

A new documentary titled “Augmented” spotlights Prof. Hugh Herr and his work developing bionic limbs at the MIT Media Lab, reports Dana Gerber for The Boston Globe. “The long-term hope for the procedure is that people with Ewing amputations will be able to further adapt to the bionic limbs shown in the film, which Herr’s team is developing at MIT,” writes Gerber.

Forbes

Forbes contributor Stephanie MacConnell spotlights the work of research affiliate Shriya Srinivasan PhD '20 in a roundup of women under the age of 30 who are transforming U.S. healthcare. Srinivasan is “working on technology that will enable patients to control and even ‘feel’ sensation through their prosthetic limb,” notes MacConnell.

Financial Times

A new amputation technique being developed by MIT researchers provides patients with more sensory feedback from prosthetic limbs, writes Anjana Ahuja for the Financial Times. “The technique could transform the way that amputation has long been viewed,” writes Ahuja, “not as a last-resort method that subtracts from the body but an act of rejuvenation with the potential to restore a sense of completeness.”

Here & Now (WBUR)

Here & Now’s Scott Tong speaks with Gideon Gil of STAT about a new technique for amputation surgery developed by researchers from MIT and Brigham and Women’s Hospital that recreates muscle connections and restore the brain’s ability to sense where and how one’s limbs are moving.
