Brain-computer interface reverses paralysis in stroke victims
St. Louis, Missouri – After three strokes that left the right side of his body paralyzed, Rick Arnold told his wife Kim that he had just one wish.
“All I really wanted to do was to be able to hold her hand. In the very beginning, it was to hold her hand,” said Arnold, a paramedic firefighter from Missouri who suffered the first of three paralyzing strokes in 2009.
These days Arnold can hold his wife’s hand again thanks in part to a new device that could potentially change the rules on how well stroke victims recover. Arnold is using brain-machine interface technology developed by Eric Leuthardt, a neurosurgeon at Washington University in St. Louis.
