Description

This guideline provides recommendations for the assessment and treatment of individuals with aphasia. These guidelines are specific to speech-language pathologists. Levels of evidence recommendations are graded A, B or C based on the following criteria: 

  • Level A: Recommendations obtained from randomized controlled trials (RCT). 
  • Level B: Recommendations obtained from well-conducted clinical studies.
  • Level C: Recommendations obtained from expert opinion.  
Recommendations
For individuals with reading impairments, treatment should focus on training the impaired component or incorporating strategies to compensate for impairment (e.g., semantic approach, improving speed and efficiency of letter identification) (Level B Evidence)

Description

This is an update of the Teasell et al. (2009) evidence-based review investigating the effectiveness of pharmacological and non-pharmacological interventions for stroke rehabilitation. Of particular interest to speech-language pathologists are the modules specific to aphasia, dysphagia, perceptual disorders and cognitive disorders. The levels of evidence used to summarize the review findings are based on the United States Agency for Health Care Policy and Research (AHCPR) criteria:  

  • Level 1a: Strong evidence supported by a meta-analysis or two or more randomized controlled trials (RCTs) with at least “fair” quality.
  • Level 1b: Moderate evidence supported by at least one RCT of “fair” quality.
  • Level 2: Limited evidence supported by at least one controlled trial with a minimum of 10 participants in each arm of the study.
  • Level 3: Findings supported by expert consensus opinion in the absence of evidence.
  • Level 4: Conflicting evidence based on disagreement between the findings of at least two RCTs. Where there are more than four RCTs, conclusions are based on the results of the majority of studies, unless conflicting results are reported in a higher quality study. 
Conclusions
"There is insufficient evidence regarding the effectiveness of alexia specific therapy. Further research is required" (Module 14; p. 50).
