Study Selection
Search results were managed using EndNote (v7.0). After removing
duplicates, two reviewers (BB, AMc) assessed study relevance by title,
then abstract, and finally full text. A third reviewer (MM) resolved
discrepancies. Articles must have met the inclusion criteria: (1)
participants had moderate-severe ABI defined as post-traumatic amnesia
>1 hour, or Glasgow Coma Scale score <13, or loss
of consciousness >15 minutes; (2) participants were 18+
years old; and (3) a dysphagia rehabilitation intervention was provided
to participants. Studies were excluded if they were a general review
article, systematic review, or scoping review (e.g., Cochrane, ASHA
evidence maps). Further, study protocols, feasibility studies, and
studies using only qualitative methodology were excluded. Participants
with mild ABIs were excluded and based on the following criteria: (1)
post-traumatic amnesia <1 hour; or (2) Glasgow Coma Scale
score of 13-15; or (3) loss of consciousness <15 minutes.
Unavailable full-text articles or conference abstracts with previously
included full-text articles were removed. Reference lists of included
studies were scanned to identify any publications missed studies.
