The results of the meta-analysis demonstrated varied effect size (MD) based on the assessment measure used. Results demonstrated that constraint-induced therapy had a significant effect on oral language and naming outcomes as measured by the Western Aphasia Battery (MD = 1.23), but no significant difference was demonstrated on outcomes as measured by the Boston Naming Test (MD = -1.79) and the Aachen Aphasia Test (MD = -4.49). These findings indicated that constraint-induced therapy may potentially improve language performance (e.g., naming, comprehension, repetition, written language, oral language). Results, however, were limited due to the poor methodological quality of the included trials.
