Study Search
A literature search was conducted for studies published from 1970 to July 2018 using the following databases: PubMed/MEDLINE, EMBASE, Web of Science, Scopus, and CINAHL. The search strategy contained three constructs: brain injury, dysphagia, and rehabilitative interventions used for patients with dysphagia; the final search strategy is shown in Appendix A. Only studies published in the English language and in peer-reviewed journals were included.
