In what is believed to be a medical first, researchers from Johns Hopkins Medicine (JHM) and the Johns Hopkins University Applied Physics Laboratory (APL) have enabled a quadriplegic man to control a pair of prosthetic arms with his mind.
In January 2019, surgeons implanted six electrodes into the brain of Robert “Buz” Chmielewski during a 10-hour operation. The goal was to improve the sensation in his hands and enable him to mentally operate his prostheses. For more than three decades after a surfing accident while in his teens, Chmielewski has been paralyzed with only minimal movement in his arms and hands.
Now, almost two years into the joint JHM/APL research study following the surgery, has reached an important milestone—he can now use both of his robotic appendages to perform simple tasks such as feeding himself.Continue reading… “Brain implants enable man to simultaneously control two prosthetic limbs with thoughts”
