Brain-Computer Interface to enable people with paralysis to go to; control of tablet devices

Other manuals and computing devices are part of daily life, but they can be difficult for people with paralysis to use them. New research from the BrainGate partnership * shows that a mental computer (BCI) interface can allow people to run the toolbar paralysis outside the shelf simply by sending them; Think about moving motions and curls.

In a study published on November 21 in PLOS ONE, there were three clinical tetraplegia test participants, each one who used BrainGate BCI research that is a? Recording an unusual activity just from a small detector that was placed in a motorcycle, capable of sailing through tablet programs, including email apps, conversation, music-streaming and video. The participants were a family member, friends, members of the research team and their partners. They encouraged the web, they looked at the weather and sold online. One partner, musician, and snippet played by Beethoven's "Ode to Joy" was a digital piano interface.

"Years ago, the BrainGate collaboration has been working to develop patient and neuroengineering experience to enable people who have lost control of motorized power on external devices just by doing so; Think about movement in the army or on the other hand, "said Dr. Jaimie Henderson, senior author of Stanford University's journal and surgery and surgery. "In this study, we have learned the knowledge of the ability of people to regenerate to control the same everyday technologies that they used before they started the illness. It's great to see the partners telling themselves or just a song they want to hear. "

BrainGate BCI research includes a child of aspirin-implant that identifies the symptoms associated with the intended motions made in the brain's motive synonym. These marks will be demolished and sent to external devices. BrainGate researchers and other organizations that use similar technologies have shown that the device can allow people to move robotic weapons or control their own games, Despite the loss of medical abilities from illness or injury. This collaboration from the collaboration involves scientists, engineers and physicians from the Carney Institute for Brain Science, Providence Veterans Medicine Center (PVAMC), Massachusetts General Hospital (MGH) and Stanford University.

Failure to lose the arms and legs move on two of the partners in this latest study as a result of lateral atleotrophic sclerosis (ALS), an acute disease that affects the nerves in the brain and spine who was managed to move. The third partner was paralyzed due to bad backbone. All were recorded in a clinical trial aimed at evaluating the safety and feasibility of the BrainGate search system.

For this study, strange features from the BrainGate BCI were moved to Bluetooth interfaces designed to work as a mice without wire. The mouse then was connected to the Google Nexus 9 tablet without changing. Then the participants were asked to set a set of actions designed to see how well they were doing; They can navigate within a variety of frequently used apps, and move from app to app. The participants spoke through music presentations on streaming services, watching videos on YouTube, scratched through news releases and their. email writing and conversations.

The survey showed that partners had up to 22 points-and-click elections every minute while they were & # 39; using a variety of apps. In text applications, the partners can write up to 30 effective characters per minute by writing. using ordinary email and text interfaces.

The participants said that the interconnected and fun interface was to be used, the study was noted. One said, "It was more natural than I remember to use mouse". Another man said "more control over this is what I usually use."

The researchers were pleased to see as soon as the participants used the table interfaces to explore their activities and interests.

"It was great to see that our partners would make the way through the actions we asked to do, but it was a worst part and fun of the survey when they just did what they wanted – to use the apps that they liked to watch videos or just talk to friends, "said the author, author Dr Paul Nuyujukian, Stanford's geologist. "Tell us one of our partners at the start of a lawsuit that music is again one of the things she really wanted to do. So, she saw playing on a good digital keyboard. "

Because the tablet devices were completely changed and all the pre-scheduled access software had been offshadowed is an important part of the survey, researchers said.

"The supportive technologies that are available today, as long as they are important and useful, are largely limited in terms of the speed of use that they enable, or the flexibility of the interface, "said Krishna Shenoy, a senior author of a electrical engineer and engineer and a specialist at Stanford University and Howard Hughes's Medicine Institute. "That's largely due to the limited signals available. With the center's wealth of the BCI, we can only buy two platforms on Amazon, move on Bluetooth and the comics can -parts are used by our BrainGate search system out of their box. "

The researchers say that the study also has the ability to open new communication lines between patients with severe adverse disasters and healthcare providers.

"This has a great potential for reliable, rapid and prosperous communication to be renewed for someone with a locked sionndrome that can not speak," said Jose Albites Sanabria, who conducted this research as a graduate student in biomedical engineering at Bria University. "Not only can they be able to communicate more with the family and their friends, but they can provide a device for more information on continuing health issues with carers . "

As a neuroscience expert and the use of essential care neurologist, the author is Dr Leigh Hochberg, the University of Bruce, Massachusetts General Hospital and the Providence VA Medical Center; see real potential for the BCI renewable capabilities set out in this study.

"When I see someone in the neuro-intensive care unit that had a bad impact on moving or communicating, I would like to say," I'm sorry but we can use the technologies you used to use before this event, and you'll be able to use it again tomorrow, "said Hochberg." And we & # 39; closer to being able to say someone who has been determined by ALS, "even while we're trying to cure, you will not lose the ability to communicate." The work This is a step for those goals. "
