Dual tasking in individuals with post-stroke aphasia: a scoping review protocol

Abstract

Objective: The purpose of this scoping review is to identify the main theoretical frameworks being used to explain dual-task performance deficits in people with post-stroke aphasia, to identify the domains of function being measured and the assessments being used, to highlight current interventions to improve dual-task performance, and to identify the gaps in the current body of literature on dual tasking and aphasia. Introduction: Post-stroke aphasia can lead to challenges across all activities of daily living. However, little is known about how a stroke and co-occurring language impairment may affect the allocation of cognitive resources, particularly in dual-task conditions. This vital information will allow researchers and clinicians to develop more effective interventions to combat the effects of the infarct. Inclusion criteria: To be considered in the review, articles must be written in English, include individuals at least 6 months post stroke, include adults with aphasia (with data presented separately from other populations), and include measures of dual-task performance. Methods: This review will be conducted in line with the JBI methodology for scoping reviews. A search of Linguistics and Language Behavior Abstracts, PsycINFO, Communication Mass Media Complete, PubMed, CINAHL Plus, ScienceDirect, and the Cochrane Library will be undertaken to identify publications on the topic. Results will be restricted to sources that meet the inclusion/exclusion criteria. Data will be extracted from included papers by up to 3 independent reviewers using a data extraction tool developed by the reviewers. The results will be presented as a narrative summary, accompanied by charted results, as appropriate. Review registration: Open Science Framework https://osf.io/2yx76
