Abstract：Somatosensory video games with technological elements have recently been utilized as aids for promoting health. Taiwan's increasingly aging population poses significant health challenges. The aging process may lead to cognitive degeneration, and cognitive function is an indicator of whether an older adult can live independently. Overseas studies have shown that somatosensory video games can help improve the cognitive function of older adults. This systematic review aimed to cover relevant literature from the Scopus, EBSCO, and PubMed databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) screening process and a selection of keywords (elderly, exergames, cognitive function, etc.) were used to screen for relevant articles published between January 2010 and December 2019; after excluding the articles that did not meet the study's criteria, 10 articles were identified and found suitable for this systematic review. Results revealed that the most common intervention was the playing of Nintendo Wii games, with 20-min play sessions being held 3 times a week. Among the studies, assessing executive function was found to be the main focus of cognitive assessments and one of the most common means of doing so was the Trail Making Test. This study concludes that older adults' participation in somatosensory video games led to improvements in their cognitive function. Future research could further investigate the correlation between cognitive function and the use of somatosensory video games in other age groups. (Full text)
