Wii Games Speed Stroke Rehab
Active Video Games Help Stroke Survivors Regain Arm Strength in Study
Feb. 25, 2010 (San Antonio) -- Active Wii video games may bring some fun into stroke recovery, helping patients regain lost strength and motor skills in the process.
In a first-of-its-kind study, 11 stroke victims with weakness in their arms could reach out and grab objects more easily and more quickly after two weeks of playing the active video games.
In contrast, 11 stroke patients who played card or block games for two weeks showed no change in arm strength afterward, says Gustavo Saposnik, MD, director of the Stroke Outcomes Research Unit at St. Michael’s Hospital in Toronto.
"For the first time, we've shown that the virtual reality gaming system is safe, feasible, and potentially effective at improving motor function after stroke," he tells WebMD.
Until the video games prove safe in larger numbers of stroke survivors -- shoulder pain being the main concern -- it’s too soon to recommend people start playing Wii games after stroke, Saposnik says.
But should the video games pan out in a study of 120 stroke patients now in the planning stage, the Canadian researchers believe they will become an adjunct to traditional stroke rehab programs.
"The great thing about gaming is that it engages the patient and motivates them to participate -- for hours. It gets them to use the [weak] arm repeatedly, which is what is needed to regain strength. And it's fun," says American Stroke Association spokeswoman Pamela Duncan, PhD, a physical therapist at Duke University in Durham, N.C. Duncan is familiar, but not involved, with the research.
Stroke Rehab With Wii Games
Saposnik says he got the idea for the study after his 5-year-old daughter told him their Wii tennis match was stacked against her.
To even out the odds, the left-handed researcher tried playing with his right hand. "It was difficult. But over time, I got better, leading me to believe [the games] could be beneficial for stroke rehabilitation," he says.
The study involved 22 people whose strokes left one arm weak, although they were able to touch their chin or opposite knee.
Two months after their stroke, half began a two-week course of video game therapy with Wii tennis and Wii Cooking Mama, which uses movements that simulate cutting a potato, peeling an onion, slicing meat, and shredding cheese.
