Robotic CORBYS platform uses patient feedback to help stroke victims walk again

By - March 13, 2013
Of the various effects that a stroke can have on a person, one of the most common is paralysis of one side of the body – needless to say, this has a severe impact on the victim’s ability to walk. Treatment often consists of therapists retraining the person’s body by repeatedly lifting their legs, guiding them through a proper walking pattern. The EU-funded CORBYS project aims to make such therapy easier for everyone involved by using a powered orthosis to move the patient’s legs in response to feedback from their brain. Read More

Researchers find molecular switch to make old brains young again

By - March 7, 2013
It’s no secret that juvenile brains are more malleable and able to learn new things faster than adult ones – just ask any adult who has tried to learn a new language. That malleability also enables younger brains to recover more quickly from trauma. Researchers at Yale University have now found a way to effectively turn back the clock and make an old brain young again. Read More

New device designed to restore brain functions – via the tongue

By - February 25, 2013
Scientists at the University of Wisconsin-Madison have created a device known as a PoNS, that shows promise for the treatment of traumatic brain injuries, strokes, or the effects of diseases such as Parkinson’s and multiple sclerosis. Researchers at the U.S. Army Medical Research and Materiel Command are now conducting a study on the device, which works by stimulating the patient’s tongue. Read More

Micro-bubbles may help prevent heart attacks and strokes

By - December 18, 2012
Heart attack and stroke-causing plaque deposits in the arteries are typically preceded by an inflammation of the arteries in those same areas. Therefore, if doctors could be aware of those inflamed regions before plaque deposits formed and problems such as chest pains arose, a lot of hardship could potentially be avoided. Well, that soon may be possible, thanks to some tiny bubbles. Read More

Polymer implants could help heal brain injuries

By - November 27, 2012
Using implants made from porous biocompatible materials, scientists have recently been successful in regrowing things such as teeth, tendons and heart tissue, plus bone and cartilage. The materials act as a sort of nanoscale three-dimensional scaffolding, to which lab-cultivated cells can be added, or that the recipient’s own cells can colonize. Now, a Spanish research team has used the same principle to grow new brain tissue – the technique could ultimately be used to treat victims of brain injuries or strokes. Read More

New device is more effective and safer than FDA-approved treatment for acute stroke patients

By - February 26, 2012 7 Pictures
A new approach to stroke treatment initially developed by Dr. Jeffrey Saver's group at the UCLA Stroke Center combines the ability to restore circulation and remove clots using only a single device ... and it's showing significant promise in trials. In a study comparing the Covidien Solitaire FR Revascularization Device with the FDA-approved Merci Retriever, the device successfully and safely treated roughly 60 percent of stroke patients, compared to roughly 30 percent when the Merci Retriever was used.

Head patch measures blood flow in stroke patients' brains

By - February 3, 2012 2 Pictures
Approximately one third of stroke patients experience another stroke while they’re still in the hospital. Nurses therefore keep a close eye on them, and arrange for them to be taken for tests if a subsequent stroke is suspected. Unfortunately these tests can be invasive, and in some cases are even potentially harmful to the patient. A new device being developed at the Mayo Clinic in Florida, however, could watch for strokes simply by shining light onto a patient’s forehead. Read More

Video game/robotics combo designed to help stroke victims recover

By - July 20, 2011
This April, researchers from Montreal's McGill University announced the development of their prototype Biomedical Sensor Glove. Stroke victims who have lost the use of their hand are intended the wear the glove, then use it at home to play custom video games on an attached computer. Not only do those games help them regain the use of their hand, but the computer also sends data regarding their gaming performance on to their physician, so they can track the patient's progress remotely. Well, it seems that Spanish researchers have now developed a similar system for the rehabilitation of paralyzed arms, called ArmAssist. Read More

Poker chip-sized device non-invasively measures brain temperature

By - May 6, 2011
Whether caused by strokes in seniors or hypoxia in newborn infants, brain injuries can cause the brain to overheat, which in turn causes its cells to die. While there are cooling therapies that can bring its temperature down, doctors first need to establish that the brain is indeed warmer than the rest of the patient’s body. While doing so has previously involved invasive techniques, researchers from Children's Hospital of The King's Daughters (CHKD) in Norfolk, Virginia have recently created a small device that sits on top of the patient’s head, and measures their brain’s temperature non-invasively.

New technique for regenerating blood vessels to aid treatment of vascular disease

By - April 18, 2011
Researchers at the University of Western Ontario have discovered a new strategy for helping the body make blood vessels in vulnerable or damaged tissue. The approach, which has implications for the treatment of victims of coronary artery disease, involves the use of a protein named fibroblast growth factor 9 (FGF9) to assist the "supporting" cells of new blood vessels as they are formed by the body.
