A new mind control device is invented by the scientists that could help the paralyzed patients regain movement in their hands.
According to a new study from Washington University in the US, “Stroke patients who learned to use their minds to open and close a device fitted over their paralyzed hands gained some control over their hands.”
Professor Eric Leuthardt,co- senior author of the study published in the journal Stroke, said: “We have shown that a brain-computer interface using the uninjured hemisphere can achieve meaningful recovery in chronic stroke patients.”
Strokes are the main reason of acquired disability among adults. People speedily recover some abilities in the first weeks after the stroke, but the progress gradually decreases after a about three months.
Thy Huskey, from The Rehabilitation Institute of St Louis in the US said, “We chose to evaluate the device in patients who had their first stroke six months or more in the past because not a lot of gains are happening by that point.”
According to one of the scientists, who developed this device, “The Ipsihand device comprises a cap that contains electrodes to detect electrical signals in the brain, a computer that amplifies the signals, and a movable brace that fits over the paralyzed hand. The device detects the wearer’s intention to open or close the paralyzed hand and moves the hand in a pincer-like grip, with the second and third fingers bending to meet the thumb.”
The study on the participants who underwent a standard motor skills evaluation at the start revealed that after 12 weeks of using the device, the patients’ scores increased an average of 6.2 points on a 57-point scale.
“An increase of six points represents a meaningful improvement in quality of life. For some people, this represents the difference between being unable to put on their pants by themselves and being able to do so,” Leuthardt said.
