Research Among People Living With Dementia or Mild Cognitive Impairment in Physiotherapy Journals: A Scoping Review.

Background And Purpose: Global estimates forecast an increase in the number of people living with dementia (PLWD) or mild cognitive impairment (MCI). Physiotherapists play an important role in the delivery of care to PLWD or MCI; however, physiotherapists report less confidence when working with PLWD or MCI, citing limited educational opportunities. Our scoping review sought to quantify and assess the type of research published in physiotherapy journals related to these groups of people.

Methods: Fifteen journals were selected based on global physiotherapy representation, indexing, and online accessibility of archives. Extraction of all articles published within a decade (2011-2021) for the selected journals was completed. Inclusion criteria: (1) research reports, reviews, case studies, or expert opinion pieces related to PLWD or MCI and (2) published in English. Each article was categorized by type of article, clinical setting, type of dementia, physiotherapy focus, and Sackett's system of hierarchy of evidence. An analysis of trends over time and a bibliometric assessment of research impact were performed.

Results And Discussion: Of 11 091 articles identified, 67 were included. The most common country of origin was the United States (38.8%). Articles were mainly research reports (70.1%), from a community-dwelling setting (50.8%), with a combined physiotherapy focus (28.4%), and a level IV (37.3%) of hierarchy of evidence. Close to half of studies did not identify the underlying dementia type (43.3%, n = 29), followed by people living with Alzheimer's dementia (28.4%, n = 19), combined groups of PLWD or MCI (20.9%, n = 14), and individuals with only MCI (7.5%, n = 5). Six articles on average related to PLWD or MCI were published annually (32.7 citation per article), and no growing trend was observed.

Conclusions: Few articles published in prominent physiotherapy journals over the last decade were related to PLWD or MCI. Publication trends remained unchanged, and publication origins were from the Americas which impacts generalizability. Physiotherapists should attain complementary information on care for PLWD or MCI through more general rehabilitation journals. Physiotherapy journals should seek to promote research related to PLWD or MCI through different avenues (eg, special issues) as increased information is needed for clinicians to feel confident in providing informed care.
