Abstract
BackgroundMaintaining or initiating regular physical activity (PA) is important for successful aging. Technology-based systems may support and stimulate older adults to initiate and persevere in performing PA. The aim of the current study was to assess to which extent a customised Kinect system is 1) a credible tool to increase PA in older adults, 2) motivating to perform PA by older adults, and 3) easy to be used in older adults.MethodsA mixed-method cross-sectional feasibility study was performed in 5 aged care facilities in Flanders, Belgium. Aged participants were asked to perform a 20–30 min test with the intelligent Activity-based Client-centred Training (i-ACT) system. After the test, the ‘Credibility and Expectancy Questionnaire’ (CEQ), the ‘Intrinsic Motivation Inventory’(IMI), the System Usability Scale (SUS), and semi-structured interviews were conducted in the older adults. Feedback was gathered using the thinking aloud method in both aged participants and healthcare professionals.ResultsA total of 48 older adults (20 males and 28 females, mean age = 81.19 (SD = 8.10)), were included. The scores pertaining to system credibility and expectancy, system usability, and motivation towards use were moderate to good. Participants reported that they liked using the i-ACT system, but that the context could be more attractive by adding more visualisations. Twelve professionals stated that they observed involvement in older adults but think that i-ACT is better used in day care centres.ConclusionsThis study indicates that i-ACT is a usable and motivational system to engage older adults to perform PA and therefore supports successful aging. Future research is necessary to investigate the efficacy of i-ACT to perform PA and the transfer to regain and/or maintain engagement in ADLs that older adults find meaningful and purposeful at an older age. Also, further development of i-ACT is advisable to adapt the i-ACT system towards implementation at the home of older adults.Trial registrationClinicalTrial.gov ID NCT04489563, 23 July 2020 - Retrospectively registered.
Highlights
Maintaining or initiating regular physical activity (PA) is important for successful aging
In total, 48 older adults, of which 20 males and 28 females, with a mean age of 81.19 (SD = 8.10), of which 16 persons lived in nursing homes and 32 persons visited day care facilities were included in the feasibility study
Regarding the results on the Intrinsic Motivation Inventory (IMI), all but one subscale scored above 4.20/7.00, which indicates good to very good motivation
Summary
Maintaining or initiating regular physical activity (PA) is important for successful aging. Technologybased systems may support and stimulate older adults to initiate and persevere in performing PA. When the years over 60–65 can be lived in good health and in a supportive environment, the ability of older adults to perform their individual meaningful activities adequately will be little different than that of a younger person [1]. Successful aging is complex, as it involves an individual’s perception, and professional evaluations (i.e. identify and evaluate different needs in unique individuals to identify the most appropriate intervention) [3]. According to Rowe and Kahn (1997), successful aging is determined by avoiding disease and disability, maintaining high cognitive and physical functioning, and staying involved with life and living [3, 4]
