July 26, 2012 -- Starting yoga even long after a stroke may improve the balance of stroke survivors, a study shows.
"It's an exciting thing," says study researcher Arlene Schmid, PhD. "People can improve their balance years after a stroke. They can change their brain and change their body. They are not stuck with what they have."
The study is published in the journal Stroke.
Schmid is a rehabilitation research scientist at Roudebush Veterans Administration-Medical Center and Indiana University in Indianapolis. For the study, her team recruited 47 stroke survivors who'd had strokes more than six months ago. Seventy-five percent of them were male veterans, including veterans of World War II.
They were divided into two groups. Ten received no therapy. The other 37 got a specialized version of yoga developed by a yoga therapist and the research team.
At first, many of the veterans scoffed at the therapy.
"'Yoga is for girls, yoga is for hippies,'" Schmid recalls them telling her. "A stereotypical male veteran's response."
After a couple of sessions, though, and with encouragement from their wives, the veterans came to appreciate yoga and the impact it had on their disabilities.
"It was a hard sell, but by the end they wanted more," Schmid says.
They practiced seated, standing, and floor-based exercises like the pigeon pose and the mountain pose over the eight-week study period. By the end, the yoga group showed significant improvement in balance.
The yoga practice also boosted their confidence and reduced their fear of falling. According to the study, nearly three-quarters of all stroke survivors suffer from falls. Such falls can break bones. They can also be fatal. In addition to physical harm, strokes can also contribute to depression.
Stroke Survivor's Recovery Is Ongoing Years After Stroke
The study sends an important message about the ability of stroke survivors to improve well after their first post-stroke year.
"I get really concerned when patients are told that improvements made after the first three to six months are the extent of the recovery they will see," says Andrea Serdar, PT, NCS, who reviewed the study for WebMD. "That's the old way of thinking, not the new science."
