Stroke patient improvement with a brain-computer interface
From: University of Adelaide - 08/31/2017

Researchers at the University of Adelaide in Australia have demonstrated a
brain-computer interface (BCI) that helps stroke patients improve motor
function. The BCI has generated a 36-percent improvement in motor function of
a stroke-damaged hand. The interface quantifies brain electrical signals on
the surface of the scalp. Each time a subject envisions performing a specific
motor function, the BCI captures those electrical signals and transmits them
to a computer. An advanced mathematical algorithm then reads the brain
signals and delivers an appropriate sensory feedback via a robotic
manipulator. "Our theory is that to achieve clinical results with BCIs we
need to have the right feedback to the brain at the right time; we need to
provide the same feedback that we receive during natural motor learning, when
we are seeing and feeling the body's movement," says Adelaide's Sam Darvishi.
"We also found there should be a short delay between the brain activation and
the activation of target muscles."
