People With Stroke Have A Chance At A Full Life.
Scientists are testing a brand-new thought-controlled widget that may one day help people get the show on the road limbs again after they've been paralyzed by a stroke. The device combines a high-tech brain-computer interface with electrical stimulation of the damaged muscles to daily patients relearn how to move frozen limbs info. So far, eight patients who had missing movement in one hand have been through six weeks of psychoanalysis with the device.
They reported improvements in their ability to complete daily tasks. "Things like combing their locks and buttoning their shirt," explained study author Dr Vivek Prabhakaran, impresario of functional neuroimaging in radiology at the University of Wisconsin-Madison. "These are patients who are months and years out from their strokes testmedplus.com. Early studies suggested that there was no tangible room for change for these patients, that they had plateaued in the recovery.
We're showing there is still apartment for change. There is plasticity we can harness". To use the new tool, patients be dressed a cap of electrodes that picks up brain signals. Those signals are decoded by a computer. The computer, in turn, sends dainty jolts of electricity through wires to sticky pads placed on the muscles of a patient's paralyzed arm.
The jolts feign like nerve impulses, giving away the whole show the muscles to move. A simple video game on the computer screen prompts patients to endeavour to hit a target by moving a ball with their affected arm. Patients practice with the game for about two hours at a time, every other day.
