Research Design: Systematic Review

A meta-analysis of research findings is reported on the effectiveness of treatments for persons suffering aphasia. Twenty-one studies provided sufficient information for inclusion in the analysis. The magnitudes of three classes of effect sizes were estimated: untreated recovery, treated recovery, and treated versus untreated recoveries. The outcomes witness the clear superiority in performance of persons receiving treatment by a speech-language pathologist.
