title: Validation of the Frenchay activity index on stroke victims.
abstract: OBJECTIVE
  To evaluate the inter-rater reliability and predictive validity of the Frenchay Activities Index (FAI) in patients after stroke.
  
  
  METHODS
  One hundred sixty-one patients were selected for consecutive application of the FAI and National Institutes of Health Stroke Scale (NIHSS). Spearman's test was used for correlation between different scales. The FAI and NIHSS association was evaluated using ordinal logistic regression. Additionally, 36 patients underwent FAI rating on the same day by two independent evaluators.
  
  
  RESULTS
  A negative correlation between the FAI and the NIHSS scores (p = 0.017 r = -0.22) was found. Adjusting all variables with possible association with the NIHSS, ordinal logistic regression showed that the FAI had a significant association with NIHSS scores (OR 0.93, 95% CI 0.87 to 0.99, p: 0.033). The inter-rater agreement was considered good, k = 0.66 (0.54 to 0.78), p < 0.001.
  
  
  CONCLUSIONS
  The FAI is a valid and useful method to assess instrumental activities before acute stroke in a Brazilian population.
