Investigating multilevel language interventions targeting spoken production in post-stroke aphasia: a scoping review...

This scoping review will identify multilevel language interventions that target spoken language production in aphasia following stroke and describe their characteristics, the theoretical predictions of the approaches, and what tools are used to measure outcomes.

Multilevel aphasia interventions target more than one linguistic level in a sequential and/or simultaneous way. Recent research has shown that treating multiple levels of language processing in the same intervention can broaden treatment effectiveness. It can also provide greater evidence of therapy gains, transferring to untreated language skills and impacting broader participation and quality of life, than focusing on language levels in isolation. Currently, there is no synthesis or analysis of multilevel aphasia interventions in the literature that might help understand the components that may contribute to these potential benefits. Conducting a scoping review will allow us to systematically explore the nature of these multilevel interventions, their proposed outcomes, and highlight directions for clinical practice and future research.

This review will consider aphasia intervention studies that aim to improve spoken production through involving more than one linguistic level in the intervention. Studies will include adults 18 years and older with post-stroke aphasia irrespective of aphasia type, severity, or time post-onset. All settings will be eligible for inclusion.

This review will be conducted in accordance with JBI methodology for scoping reviews. CINAHL, MEDLINE, PsycINFO, and Scopus will be searched for published articles. 2 reviewers will independently screen articles for relevance against the inclusion criteria. Data will be presented in tables, accompanied by a narrative summary.
