Identifying the Research Question
A scoping review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) (19) and informed by the methodological framework described by Arksey and O’Malley (20). Scoping reviews address a research question aimed at mapping key concepts, types of evidence and gaps in research related to a defined field. They are useful to identify literature regardless of study design or data heterogeneity (20). Therefore, a scoping review was deemed appropriate given the scarce literature in ABI and dysphagia. The research question identified was: What literature is available investigating dysphagia-specific interventions for moderate-severe ABI in the acute and chronic phase of recovery?
