People With Stroke Have A Chance At A Full Life.
Scientists are testing a original thought-controlled apparatus that may one day help people start 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 mitigate patients relearn how to move frozen limbs. So far, eight patients who had gone movement in one hand have been through six weeks of remedy with the device.
They reported improvements in their ability to complete daily tasks. "Things like combing their plaits and buttoning their shirt," explained study author Dr Vivek Prabhakaran, official of functional neuroimaging in radiology at the University of Wisconsin-Madison. "These are patients who are months and years out from their strokes. Early studies suggested that there was no genuine room for change for these patients, that they had plateaued in the recovery.
We're showing there is still cell for change. There is plasticity we can harness". To use the new tool, patients damage 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 deport oneself like nerve impulses, striking the muscles to move. A simple video game on the computer screen prompts patients to seek 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.

New Methods Of Diagnosis Of Stroke
New Methods Of Diagnosis Of Stroke.
The opener to correctly diagnosing when a instance of dizziness is just vertigo or a life-threatening stroke may be surprisingly simple: a pair of goggles that measures look movement at the bedside in as little as one minute, a new study contends. "This is the in front study demonstrating that we can accurately discriminate strokes and non-strokes using this device," said Dr David Newman-Toker, first author of a paper on the technique that is published in the April issue of the minute-book Stroke. Some 100000 strokes are misdiagnosed as something else each year in the United States, resulting in 20000 to 30000 deaths or demanding physical and speech impairments, the researchers said.
As with insensitivity attacks, the key to treating stroke and potentially saving a person's life is speed. Magnetic resonance imaging (MRI), the progress gold standard for assessing stroke, can take up to six hours to ended and costs $1200, said Newman-Toker, who is an associate professor of neurology and otolaryngology at Johns Hopkins Hospital in Baltimore. Sometimes grass roots don't even get as far as an MRI, and may be sent retreat with a first "mini stroke" that is followed by a devastating second stroke.
The new study findings come with some significant caveats, however. For one thing, the scrutiny was a small one, involving only 12 patients. "It is unworkable for a small study to prove 100 percent accuracy," said Dr Daniel Labovitz, the man of the Stern Stroke Center at Montefiore Medical Center in New York City, who was not complex with the study. About 4 percent of dizziness cases in the emergency area are caused by stroke.
The other caveat is that the device is not yet approved in the United States for diagnosing stroke. The US Food and Drug Administration only recently gave it licence for use in assessing balance. It has been at one's disposal in Europe for that purpose for about a year. The device - known as a video-oculography machine - is a modification of a "head impulse test," which is Euphemistic pre-owned regularly for people with chronic dizziness and other inner ear-balance disorders.
