Özet
Aims: This systematic review investigates the effectiveness of verb production training in individuals with agrammatic Broca’s aphasia. It highlights verb retrieval and verb inflection treatments, evaluating their impact on naming accuracy, sentence production, and generalization. The ultimate goal of the present study is to systematically review and evaluate the effectiveness of verb production training methods—including both verb retrieval and verb inflection interventions—for improving communication outcomes in patients with agrammatic Broca’s aphasia. Methods: This review followed the PRISMA 2020 guidelines. Four databases (PubMed, Medline/EBSCOhost, Web of Science, and Google Scholar) were searched using PICO-based terms. Inclusion criteria consisted of peer-reviewed articles in English which exclusively focused on verb production training in agrammatic Broca’s aphasia with measurable outcomes. Exclusion criteria included studies on other aphasia types, non-intervention papers, and non-English or unavailable full texts. After removing duplicates and screening 1461 records, ten studies met the eligibility criteria. Results: Of the ten studies included, six focused on verb retrieval treatments and four on verb inflection treatment. Interventions varied widely, including semantic, gestural, and repetition-based methods for verb retrieval and morphosemantic and morphophonological treatments for verb inflection. While verb retrieval treatments improved naming of trained verbs, generalization to untrained items was inconsistent. Morphosemantic approaches to verb inflection outperformed morphophonological treatments and had broader generalization and improvements in narrative tasks, particularly with regular verb training. Overall, participant response varied depending on the nature of the impairment and treatment modality. Conclusion: Verb production training is effective in improving targeted linguistic abilities in agrammatic Broca’s aphasia, particularly when approaches are tailored to individual deficits. Morphosemantic and multimodal interventions demonstrate promising results. However, limited generalization to untrained contexts remains a key challenge, highlighting the need for future therapies that integrate semantic, syntactic, and real-life communicative components.
