Sensor-laden connected sleeve designed to boost stroke rehab

Patients recovering from strokes are often released from the hospital with exercises to do, in order to recover full function of their arm/hand. The problem is, doing those exercises alone and at home, they may not even know if they start doing them incorrectly. That's why a team of scientists in the UK is creating an electronic sleeve-based system, that ensures everything is getting done right.

New blood clot-busting nanocapsule promises immediate care for heart attacks

When blood clots form in the aftermath of a heart attack or stroke, medications can be deployed to break them apart, but delivery is tricky. Getting the medicine to the clot takes some guesswork and there's no guarantee it will arrive in the right dosage, with complications like hemorrhaging a real possibility. A team of Australian scientists has developed a new approach that sees the drugs carried safely inside a nanocapsule, opening up the treatment to more patients and lessening the chance of side effects.

Juvenile plasticity returned to adult mice brains

By enabling the rigid brains of adult mice to return to the high levels of plasticity found in juvenile brains, scientists are opening new pathways to the treatment of brain injuries such as stroke. Back in 2013, researchers from Yale University reported the discovery of a molecular switch that achieved this result, and now scientists at the University of California, Irvine, have managed to make an old brain young again using a different approach.

Magnetic nanoparticles quickly bust blood clots to promise improved stroke prevention

Tissue plasminogen activator (tPA) is a drug commonly used by surgeons to bust open blood clots in a patient's bloodstream, but it does have its limitations. Once injected, there's no guarantee it will reach the site of the blood clot, and even then, having it arrive in the correct dosage can be tricky, with the risk of hemorrhage a very real possibility. Researchers have now found that using a new type of magnetic nanoparticle to deliver the drug offers a much more efficient journey to the site, promising to destroy blood clots 100 to 1,000 times faster and aid significantly in the prevention of heart attacks and strokes.

FDA approves blood test that predicts risk of coronary heart disease

Coronary heart disease (CHD) kills more than 385,000 people in the United States each year, and more than half of those who die suddenly have no previous symptoms. A new blood test that could reduce CHD-related illness and mortality by predicting the risk of future heart disease has been cleared by the US Food and Drug Administration (FDA). The PLAC Test for Lp-PLA2 screens for cardiovascular inflammation which can lead to a build up of rupture-prone plaque and result in a heart attack or stroke. Read More

Adapted Wii games aid in stroke victim rehab

Paralysis or problems controlling movement are among the most common disabilities resulting from stroke and have a major impact on everyday life. Lancaster University researchers say seven out of 10 stroke survivors suffer from arm weakness as a result of their stroke, and only a fifth of these people ever regain the full use of their arm. A new study suggests the Nintendo Wii could provide an effective, economical and fun rehabilitation tool for stroke victims. Read More

Small adhesive patch outperforms traditional tech for detecting arrhythmia

Ordinarily, when doctors wish to monitor an ambulatory patient for heartbeat irregularities, they have them wear what is know as a Holter monitor. The device is fairly cumbersome, so it's usually worn for no more than 24 hours. A recent study, however, indicates that the relatively new ZIO Patch provides more accurate readings, while being considerably less obtrusive. Read More

Rehabilitative device bridges the gap between stroke victims' brains and hands

We've recently seen rehabilitative systems in which stroke victims use their thoughts either to move animated images of their paralyzed limbs, or to activate robotic devices that guide their limbs through the desired movements. Scientists at the University of Wisconsin-Madison, however, have just announced an alternative approach. Their device acts as an intermediary between the brain and a non-responsive hand, receiving signals from the one and transmitting them to the other. Read More

AMES device helps the paralyzed regain movement

Last week, the US Food and Drug Administration granted clearance to a new device that could be of considerable aid to stroke victims or people with partial spinal cord injuries. Created by Dr. Paul Cordo of the Oregon Health & Science University (OHSU) in collaboration with OHSU spinoff company AMES, the "AMES device" reportedly helps the brain get paralyzed muscles moving again.
