title: Ability to negotiate stairs predicts free-living physical activity in community-dwelling people with stroke: an observational study.
abstract: OBJECTIVE
  Which clinical measures of walking performance best predict free-living physical activity in community-dwelling people with stroke?
  
  
  METHODS
  Cross-sectional observational study.
  
  
  METHODS
  42 community-dwelling stroke survivors.
  
  
  METHODS
  Predictors were four clinical measures of walking performance (speed, automaticity, capacity, and stairs ability). The outcome of interest was free-living physical activity, measured as frequency (activity counts) and duration (time on feet), collected using an activity monitor called the Intelligent Device for Energy Expenditure and Physical Activity.
  
  
  RESULTS
  Time on feet was predicted by stairs ability alone (B 166, 95% CI 55 to 278) which accounted for 48% of the variance. Activity counts were also predicted by stairs ability alone (B 6486, 95% CI 2922 to 10 050) which accounted for 58% of the variance.
  
  
  CONCLUSIONS
  The best predictor of free-living physical activity in community-dwelling people with stroke was stairs ability.
