Oct. 10, 2011 -- People who can cross their legs soon after a major stroke may have much better odds of a good recovery than those who cannot.
A new study shows people who crossed their legs within 15 days of a severe stroke were less likely to die and more likely to be walking and independent compared to those who did not.
For example, only one of the 34 people (9%) who crossed their legs died within one year of leaving the hospital compared with 18 of the 34 (53%) who did not cross their legs.
Researchers say they were astonished with the results.
"We were in the ICU doing our rounds and would notice, 'Oh look, he is crossing his legs, doesn't he look comfortable. He might have a good outcome,'" says researcher Berend Feddersen, MD, PhD, assistant professor of neurology at the University of Munich, in Germany. "It was really surprising that it was in fact such a good marker, especially one year after the stroke."
They say if further studies confirm the results of this small study, leg crossing may become a valuable indicator of future stroke recovery among those with severe strokes.
The researchers followed 34 people who had suffered a severe stroke and crossed their legs during their stay at a German hospital. They matched the leg crossers to 34 randomly selected people who did not cross their leg following a severe stroke.
All of the participants were evaluated when they were admitted to the hospital, on the day of leg crossing, when they were discharged from the hospital, and one year after discharge.
At the time of admission, researchers say there were no significant differences between the two groups in terms of level of neurological impairment, independence, and disability.
But researchers found people who crossed their legs within 15 days of their stroke had fewer neurological problems when they were discharged from the hospital than those who did not cross their legs.
Leg crossers scored an average of 6.5 on the National Institutes of Health (NIH) stroke scale, a measure of stroke severity and impairment, compared with an average score of 10.6 for non-leg-crossers.
