Effects of Virtual Reality Sessions on the Quality of Life, Happiness, and Functional Fitness among the Older People: A Randomized Controlled Trial from Taiwan

Background and Objective: Ageing is a complex process with physical, psychological, and social changes, which can lead to diseases and disability, and further reduce happiness levels. Virtual reality (VR) is an emerging technology with the potential to improve overall well-being, quality of life (QoL), muscle activity and balance. Our study aimed to determine the influence of VR sessions on the QoL, happiness, and functional fitness components of an elderly cohort. Methods: A non-blinded randomized controlled trial was conducted. Sixty participants, who visited the active ageing center at the university were randomized into two groupsintervention and control. The intervention group received VR experience sessions for 15 min twice a week for a duration of 6 weeks, while the control group received no sessions. Participants filled out a questionnaire for QoL assessment and happiness assessment. They were also tested for several functional fitness components. Both questionnaires and fitness tests were conducted at the beginning and at the end of study. Results: QoL improved by some metrics assessed (Pain/Discomfort and Anxiety/Depression). Happiness significantly improved in the intervention group relative to the control group. Among the functional fitness tests, the back scratch test 1st and back scratch test 2nd were measured to be significantly improved in the intervention group in comparison to control group. Conclusions: VR sessions have potential to influence the well-being and functional fitness of older adults and further support the process of healthy and active ageing. Future considerations could focus on supporting more physical and psychological aspects of the older people through VR content. Trial registration: NCT04166747. (c) 2020 Elsevier B.V.
