Tai Chi exercise may reduce falls in adult stroke survivors

Abstract: P362

2013-02-06
(Press-News.org) Tai Chi may reduce falls among adult stroke survivors, according to research presented at the American Stroke Association's International Stroke Conference 2013. Compared to survivors receiving usual care or participating in a national fitness program for Medicare-eligible adults called SilverSneakers®, those practicing Tai Chi had the fewest falls. Tai Chi is a martial art dating back to ancient China. It includes physical movements, mental concentration and relaxed breathing. "Learning how to find and maintain your balance after a stroke is a challenge," said Ruth E. Taylor-Piliae, Ph.D., R.N., the study's principal investigator and assistant professor at the University of Arizona College of Nursing in Tucson, Ariz. "Tai Chi is effective in improving both static and dynamic balance, which is important to prevent falls. Tai Chi is readily available in most U.S. cities and is relatively inexpensive." Stroke survivors experience seven times as many falls each year than healthy adults, Taylor-Piliae said. These falls can cause fractures, decrease mobility and increase fear of falling that can result in social isolation or dependence. Tai Chi has significantly reduced falls in healthy older adults. Researchers recruited 89 stroke survivors — most of whom had ischemic strokes — for a randomized prospective study outside of a hospital setting. Participants were an average 70 years old, 46 percent were women and most Caucasian, college educated and living in the Tucson area, and suffered a stroke on average three years prior to beginning the study. Among the participants, 30 practiced Tai Chi, 28 took part in usual care and 31 participated in SilverSneakers®. The Tai Chi and SilverSneakers® groups participated in a one-hour exercise class three times each week for 12 weeks. The usual care group received a weekly phone call and written material about participating in community-based physical activity. During the 12-week trial, there were a total of 34 reported falls in participants' homes mainly from slipping or tripping: five falls in the Tai Chi group; 15 falls in the usual care group; and 14 falls in the Silver Sneakers group. Only four people sought medical treatment. Yang-style Tai Chi, as practiced in the study, is the most popular of five styles used in the United States because of its emphasis on health benefits, both physical and psychosocial benefits, researchers said. "The main physical benefits of Tai Chi are better balance, improved strength, flexibility and aerobic endurance," Taylor-Piliae said. "Psycho-social benefits include less depression, anxiety and stress, and better quality of life." ### Co-authors are: Tiffany Hoke, R.N.; Bijan, Najafi, Ph.D.; and Bruce Coull, M.D. Author disclosures are on the abstract.

Brain research provides clues to what makes people think and behave differently
2013-02-06
Differences in the physical connections of the brain are at the root of what make people think and behave differently from one another. Researchers reporting in the February 6 issue of the Cell Press journal Neuron shed new light on the details of this phenomenon, mapping the exact brain regions where individual differences occur. Their findings reveal that individuals' brain connectivity varies more in areas that relate to integrating information than in areas for initial perception of the world. "Understanding the normal range of individual variability in the human ...

Induction of mild inflammation leads to cognitive deficits related to schizophrenia

2013-02-06
Researchers at the Institute for Comprehensive Medical Science, Fujita Health University and the National Institute for Physiological Sciences, Japan, along with colleagues from 9 other institutions, have identified an exceptional mouse model of schizophrenia. After screening over 160 mutant mouse strains with a systematic battery of behavioral tests, they identified a mutant mouse lacking the Schnurri-2 protein (Shn-2 KO) that exhibits behavioral deficits and other brain features consistent with schizophrenia. Shn-2 is an NF-B site-binding protein that binds enhancers ...

The wings of the Seagull Nebula

The wings of the Seagull Nebula
2013-02-06
Running along the border between the constellations of Canis Major (The Great Dog) and Monoceros (The Unicorn) in the southern sky, the Seagull Nebula is a huge cloud mostly made of hydrogen gas. It's an example of what astronomers refer to as an HII region. Hot new stars form within these clouds and their intense ultraviolet radiation causes the surrounding gas to glow brightly. The reddish hue in this image is a telltale sign of the presence of ionised hydrogen [1]. The Seagull Nebula, known more formally as IC 2177, is a complex object with a bird-like shape that is ...

Study points to possible cause of, and treatment for, non-familial Parkinson's

2013-02-06
New York, NY (February 6, 2013) — Columbia University Medical Center (CUMC) researchers have identified a protein trafficking defect within brain cells that may underlie common non-familial forms of Parkinson's disease. The defect is at a point of convergence for the action of at least three different genes that had been implicated in prior studies of Parkinson's disease. Whereas most molecular studies focus on mutations associated with rare familial forms of the disease, these findings relate directly to the common non-familial form of Parkinson's. The study was published ...

X-rays reveal uptake of nanoparticles by soya bean crops

X-rays reveal uptake of nanoparticles by soya bean crops
2013-02-06
Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the food chain. The study was published on 6 February 2013 in the journal ACS Nano. The international research team was led by Jorge Gardea-Torresdey ...

Earth-like planets are right next door

Earth-like planets are right next door
2013-02-06
Using publicly available data from NASA's Kepler space telescope, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that six percent of red dwarf stars have habitable, Earth-sized planets. Since red dwarfs are the most common stars in our galaxy, the closest Earth-like planet could be just 13 light-years away. "We thought we would have to search vast distances to find an Earth-like planet. Now we realize another Earth is probably in our own backyard, waiting to be spotted," said Harvard astronomer and lead author Courtney Dressing (CfA). Dressing ...

Study: Firms that purport to value shareholders pay CEOs more

Study: Firms that purport to value shareholders pay CEOs more
2013-02-06
CHAMPAIGN, Ill. — Ever wonder why CEOs at poorly performing companies continue to receive exorbitant pay packages? According to a study from a University of Illinois labor professor, firms that trumpet how much they value shareholders actually pay their CEOs more, regardless of the quality of their performance as executives. Using compensation data from 290 chief executives at large U.S. firms over an 11-year period, Taekjin Shin, a professor of labor and employment relations at Illinois, shows that CEOs at firms with the appearance of a "shareholder-value orientation" ...

Environmental factors determine whether immigrants are accepted by cooperatively breeding animals

2013-02-06
Cichlid fish are more likely to accept immigrants into their group when they are under threat from predators and need reinforcements, new research shows. The researcher suggests that there are parallels between cooperatively breeding fish's and humans' regulation of immigrants. The research was published today, 6 February 2013, in the journal Proceedings of the Royal Society B. The Princess of Lake Tanganyika (Neolamprologus pulcher), a cichlid fish which is popular in home aquariums, are cooperatively breeding fish with a dominant breeding pair and several 'helper' ...

Nothing fishy about swimming with same-sized mates

2013-02-06
Have you ever wondered why, and how, shoals of fish are comprised of fish of the same size? According to new research by Ashley Ward, from the University of Sydney in Australia, and Suzanne Currie, from Mount Allison University in Canada, fish can use a variety of different sensory cues to locate shoal-mates, but they are able to use chemical cues to find other fish of the same size as themselves. Using these cues, they can form a group with strength in numbers. The work is published online in Springer's journal, Behavioral Ecology and Sociobiology. Forming groups is ...

Biocontrol research on Brazilian peppertree in Florida discovers new cryptic species
2013-02-06
Dr Michael Pogue, a Research Entomologist in the ARS Systematic Entomology Laboratory, at the Smithsonian Institution, Washington, DC, was sent a series of moth specimens from Bahia, Brazil, for identification. The insects were under consideration as a possible biocontrol agent for the invasive Brazilian peppertree in Florida. 'The species was initially identified as a common species, but when comparisons were made, it became evident that there were multiple species involved' said Dr. Pogue. Using characters from the moths' male and female genitalia, Dr. Pogue determined ...
