title: Accuracy of clinical observations of push-off during gait after stroke.
abstract: OBJECTIVE
  To determine the accuracy (criterion-related validity) of real-time clinical observations of push-off in gait after stroke.
  
  
  METHODS
  Criterion-related validity study of gait observations.
  
  
  METHODS
  Rehabilitation hospital in Australia.
  
  
  METHODS
  Eleven participants with stroke and 8 treating physical therapists.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Pearson product-moment correlation between physical therapists' observations of push-off during gait and criterion measures of peak ankle power generation from a 3-dimensional motion analysis system.
  
  
  RESULTS
  A high correlation was obtained between the observational ratings and the measurements of peak ankle power generation (Pearson r =.98). The standard error of estimation of ankle power generation was .32W/kg.
  
  
  CONCLUSIONS
  Physical therapists can make accurate real-time clinical observations of push-off during gait following stroke.
