不少病人中風後，活動能力大不如前，部分人即使進行物理治療亦未必有好轉。美國一項最新研究就發現，打機有助修復中風患者的腦細胞連繫，改善他們的手臂強度及活動能力。( u( o0 W! `5 a

美國多倫多大學的研究發現，中風患者在四至六星期的時間內，打機二十至三十個小時，無論是傳統的電視遊戲或虛擬實境遊戲，均可改善他們的身體活動能力。其中玩虛擬實境遊戲的患者，可分別提升上臂強度一成半及肢體運動功能兩成。
負責有關研究的Saposnik教授指，遊戲有助腦部產生新的腦細胞連繫，稱為重新修復。而一些具重複性、新奇、刺激的活動如打遊戲機，則有助加速重新修復腦部功能。不過，他指現時相關的研究項目太少，難以作出結論。

Virtual reality may lead to real-world improvement for stroke patientsPosted On: April 7, 2011 - 8:30pm- h' {6 \+ N. ^6 u# V2 s

Virtual reality (VR) and other video games led to significant improvement in arm strength following stroke and could provide an affordable, enjoyable and effective way to intensify treatment, according research reported in Stroke: Journal of the American Heart Association.

Researchers analyzed seven observational and five randomized trials, representing a total of 195 patients, ages 26 to 88, who had suffered mild to moderate strokes.& p: I" N. u( x/ C3 o
Each study had investigated the effects of electronic games on upper arm strength and function.
In the observational studies, there was an average 14.7 percent improvement in motor strength after virtual reality sessions. There was a 20 percent average improvement in motor function, or the ability to perform standard tasks. In the randomized clinical trials, patients who played virtual reality games showed a statistically significant 4.89 times higher chance of improvement in motor strength compared to those who got standard therapy.
"Virtual reality gaming is a promising and potentially useful alternative to enhance motor improvement after stroke," said Gustavo Saposnik, M.D., M.Sc., lead author of the study and director of the Stroke Outcomes Research Unit at St. Michael's Hospital at the University of Toronto. "Virtual reality gaming therapy may provide an affordable, enjoyable and effective alternative to intensify treatment and promote motor recovery after stroke."  K2 ]: f, P( z+ ~: ]
Between 55 percent and 75 percent of stroke survivors continue to experience motor deficits that reduce their quality of life, yet conventional therapy provides "modest and sometimes delayed effects," said Saposnik, also an assistant professor in the hospital's department of medicine.公仔箱論壇" b# [" G7 G& ~# w3 a9 E& \
Recent research indicates the brain has a remarkable potential for remodelling because after injury it shows neuroplasticity, the ability to create new nerve cell connections. Those studies indicate that training designed to maximize the brain's remodelling potential should be challenging, repetitive, task-specific, motivating and novel. All of those are qualities of video-gaming, especially virtual reality systems in which players interact with a multisensory simulated environment via a wireless controller and receive real-time feedback on their performance.
Saposnik said advantages of virtual reality systems include: www2.tvboxnow.com* W0 `& ~4 e! i3 N, E: V

real-time feedback providing immediate positive reinforcement;

multi-sensorial feedback, including vision, hearing and sensory perception;
computer-assisted movement;
simple graphics; and
potential for modifiable speed that enables participation over a wide range of patients including those with a cognitive impairment.

Although treatment varied by study, most patients played 20 to 30 hours during four to six weeks of therapy on one of several computer-based technology systems: three traditional video game systems (i.e., Glasstron, IREX®, Playstation® Eye Toy® and nine virtual reality systems (i.e., Virtual Teacher, CyberGlove, VR Motion, PneuGlove, Wii™).
The observational studies followed patients in treatment to monitor changes over time. The randomized trials – considered more scientifically rigorous – randomly assigned two groups of patients to get either standard or virtual reality therapy.
Some of the smaller studies added virtual reality or video gaming on top of conventional therapy, which Saposnik said could limit this pooled analysis by skewing results for those who received more therapy. So far, there have been no large (more than 100 patients), randomized, controlled trials that compared the combination of virtual reality with conventional physical and occupational therapy to conventional treatment alone. That kind of study is needed, Saposnik said.
