Animal-assisted services for adults with acquired neurogenic communication disorders: A scoping review

BackgroundThere is increasing interest in the incorporation of animal-assisted services (AAS) in therapy for adults with acquired neurogenic communication disorders. AAS have the potential to enhance speech and language therapy engagement and outcomes. However, a greater understanding of the nature and potential benefits of these interventions is needed.AimsTo describe the existing evidence for the incorporation of AAS in therapy with adults with acquired neurogenic communication disorders and to identify areas for future research.Methods & ProceduresA scoping review was conducted and reported in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist extension for scoping reviews (PRISMA-ScR). Seven databases (PubMed, Embase, CINAHL, PsycINFO, Cochrane, Scopus, Web of Science) and grey literature (Google) were searched. Two reviewers independently screened titles, abstracts and full texts against eligibility criteria using Covidence software. The Template for Intervention Description and Replication (TIDieR) checklist guided extraction of intervention data.Main ContributionsA total of 17 studies with adults with aphasia, apraxia of speech and cognitive-communication disorders were included. While terminology varied, most interventions met the definition of animal-assisted therapy or animal-assisted activity and used therapy dogs. Across studies, a range of outcomes were targeted, and positive benefits were reported for participant mood, emotions, motivation and satisfaction. There were mixed, but mostly positive, benefits on social behaviour, communication and participation.Conclusions & Implications:AAS has been incorporated in therapy for adults with acquired neurogenic communication disorders, predominately with people with dementia. Across studies, communication impairments and AAS interventions were insufficiently or inconsistently described. Improved reporting would assist understanding of the potential benefits of AAS as an adjunct therapy. A quality appraisal of existing studies, and meta-analysis of findings, is needed to draw conclusions about the effectiveness of AAS as a complementary therapy for people with acquired neurogenic communication disorders.
