CHAMPAIGN, Ill. — Researchers used accelerometers to measure daily physical activity in 30 stroke survivors for a week, assessing how much the participants moved and how well they performed routine physical tasks. The study revealed that stroke survivors who engaged in a lot of light physical activity – taking leisurely walks or attending to nonstrenuous household chores, for example – also reported fewer physical limitations than their more sedentary peers.

The researchers describe their findings in the American Journal of Physical Medicine and Rehabilitation.

“Stroke is a major cause of disability in older adults,” said Neha Gothe, a professor of kinesiology and community health at the University of Illinois at Urbana-Champaign who led the research. “We know that physical activity can improve how well people survive a stroke and recover after the fact. But almost no research has looked at how physical activity of different intensities affects physical function among stroke survivors.”

Gothe and her research team used two measures of physical ability – the Short Physical Performance Battery, which measures balance, walking speed and lower-limb endurance, and the Late-Life Function and Disability Instrument, which asks participants to report how difficult it is for them to perform daily tasks such as getting in and out of a car or pouring water from a heavy pitcher.
