Investigating the biomechanics of falls in older adults in long-term care using a video camera: a scoping review

BackgroundFalls are a worrying and growing phenomenon worldwide that especially affects the elderly. With the development of technology, one way of studying the real-life falls that occur in healthcare settings is by using video cameras.AimsTo (a) map the patterns of the research on real-life falls among older adults in healthcare settings as assessed with digital video camera supports; and (b) highlight the advances, the evidence produced, and the gaps still present regarding the biomechanics of falls as assessed technologically.MethodsA scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. CINAHL, PubMed and Google Scholar were searched. All studies regarding falls investigated with video cameras among older individuals in healthcare settings published from 1st January 1990 to 1st January 2022 were eligible. Findings were summarised according to the Patterns, Advances, Gaps, Evidence and Recommendations framework for Scoping Reviews.ResultsIn total, 1943 studies were retrieved, and 16 met the inclusion criteria. Studies were mostly conducted in Canada. They described the real-life falls that occurred mainly in common and living areas of long-term facilities among older individuals, mainly females. Thirteen studies investigated falls through biomechanics, while three provided advances in the reliability of the measures as collected with video cameras. Studies reported that the biomechanics of a fall, reflecting the direction of the fall and protective responses, increase or decrease the likelihood of serious impact. In addition, the direction of the landing after a fall has been determined as having a significant impact on the severity and outcome of the fall.ConclusionThe use of video cameras to investigate the biomechanics of falls is a well-established research area that offer interesting insight regarding (a) how to prevent falls and their injuries and (b) the direction of the research in the field of falls.
