New research says that people who are able to cross their legs soon after having a severe stroke appear to be more likely to have a good recovery compared to people who cannot do the same.
The research is published in the October 11, 2011, print issue of Neurology
, the medical journal of the American Academy of Neurology.
"Despite having severe strokes that left them with slight loss of movement and even reduced consciousness, we noticed that some people were still able to cross their legs, which is not as easy as it seems," said study author Berend Feddersen, MD, PhD, of the University of Munich, Germany. "If this finding is confirmed, leg crossing may be an easy way to help doctors determine who may have a better chance of recovery."
People who were able to cross their legs within the first 15 days after a severe stroke were more likely to have better independence in daily life, fewer neurologic problems and lower death rates.
The study involved 68 people who had experienced a severe stroke with need of intensive care treatment including need of ventilation or need of circulatory support. Two groups of 34 were formed; one group with leg-crossers and one with non-leg-crossers. Participants were followed for one year and were tested using several scales to measure disability and independence.
After one year, the study found that one person, or nine percent, died among those who were able to cross their legs after stroke compared to 18 people, or 53 percent, who died among those who couldn't cross their legs.
In addition, both groups were given a score using the NIH Stroke Scale, which predicts outcome and severity of stroke. The leg crossing group had fewer neurologic problems at discharge from the hospital, scoring an average of 6.5 on the stroke scale, notably lower than the non-crossers who had an average score of 10.6.
One year after discharge, the leg-crossers scored an average of 2.9 on the Rankin Scale, indicating they were only moderately disabled and capable of walking unassisted compared to non-crossers, who scored an average of five on the Rankin Scale, indicating they were severely disabled and required constant attention.
As for daily independence, people who were able to cross their legs also fared better. They scored an average of 34 out of 100 on the Barthel Index test, compared to a score of 21 at discharge, and then received a score of 71 one year later compared to 49 for those who couldn't cross their legs. A score of zero indicates full dependence, while a score of 100 indicates full independence.
