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?
