title: Identification of aphasia post stroke: a review of screening assessment tools.
abstract: BACKGROUND
  Aphasia is one of the most common consequences of stroke. Early identification, diagnosis and treatment of language deficits are important steps in maximizing rehabilitation gains. A routine screening test is an invaluable tool in the identification and appropriate referral of patients with potential communication problems. The present study presents an evaluation of the measurement properties of screening tools for aphasia found within the stroke research literature.
  
  
  METHODS
  Screening tools were identified following searches of the published research literature in stroke. Instruments were reviewed on the basis of reliability, validity, classification sensitivity and practical utility.
  
  
  RESULTS
  Six aphasia screening tools were identified. For most tools, information pertaining to measurement properties and clinical utility was limited.
  
  
  CONCLUSIONS
  The Frenchay Aphasia Screening Test (FAST) appears to be the most widely used and thoroughly evaluated tool found within the stroke research literature. Further evaluation of the measurement properties and clinical utility of screening tools is recommended.
