Researchers at University of Minnesota, Minneapolis, have found that a virtual reality platform that makes use of a sensorimotor rhythm-brain-computer interface can help in the rehabilitation of stroke victims by helping them reactivate damaged regions of their brain.
Researchers led by Alexander Doud tested the platform on a group of six patients, two survivors of cortical stroke and four survivors of basal ganglia stroke, along with a control group of four healthy people. All of the participants were given with 3-D anaglyph glasses that produced an illusion of seeing one's arms through the lid of the stimulus box and sent signals to a computer through electrodes, fitted to their heads, by using their imagination.
The researchers found that the patients were able to imagine reaching out for a glass of water with 81 percent accuracy after just three sessions of two hours each. The study has been presented at the American Heart Association's Scientific Sessions meeting in Texas.
