BACKGROUND Physical activity leads to improvements in morbidity, mortality and quality of life, especially when it is progressive, challenging and regular. There is strong evidence that strength and balance exercises decrease the risk of falling. However, traditional exercises may be tedious and not very motivating for participants. Exergames have been found to increase engagement and enjoyment for older users. OBJECTIVE The aim of this study is to conduct a feasibility randomised controlled trail (RCT) on the use of MIRA Rehab exergames among older male residents in a care home setting in Saudi Arabia. METHODS With the goal of achieving a sample of 30 eligible participants. we will recruit 38 residents in the care home who will be randomly allocated to either the intervention or control group. The intervention participants will perform gamified exercises using the MIRA telerehabilitation platform (30 minutes three times per week for six weeks). The control group will receive educational advice based on OTAGO exercise programme booklets and be encouraged to exercise (30 minutes three times per week for six weeks). Participants will be assessed at Week 0, Week 6 and Week 12. Assessments will include feasibility measures (eligibility, recruitment and attrition rates, and practicalities of data collection methods) and participant outcome measures (balance, strength, mobility, adherence, quality of life, fear of falling, depression, acceptability and usability). RESULTS NA CONCLUSIONS Based on this feasibility RCT, we will design a definitive RCT to test whether the MIRA Rehab exergame programme benefits older people in Saudi Arabia who may not like participating in traditional exercise programmes and may be unwilling or unable to leave their homes. CLINICALTRIAL Feasibility RCT is not required for registration

BACKGROUND Older people are at increased risk of adverse health events because of reduced physical activity. There is concern that activity levels are further reduced in the context of the COVID-19 pandemic, as many older people are practicing physical and social distancing to minimize transmission. Mobile health (mHealth) and eHealth technologies may offer a means by which older people can engage in physical activity while physically distancing. OBJECTIVE The objective of this study was to assess the evidence for mHealth or eHealth technology in the promotion of physical activity among older people aged 50 years or older. METHODS We conducted a rapid review of reviews using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched for systematic reviews published in the English language in 3 electronic databases: MEDLINE, CINAHL Plus, and Scopus. Two reviewers used predefined inclusion criteria to select relevant reviews and extracted data on review characteristics and intervention effectiveness. Two independent raters assessed review quality using the AMSTAR-2 tool. RESULTS Titles and abstracts (n=472) were screened, and 14 full-text reviews were assessed for eligibility. Initially, we included 5 reviews but excluded 1 from the narrative as it was judged to be of critically low quality. Three reviews concluded that mHealth or eHealth interventions were effective in increasing physical activity. One review found that the evidence was inconclusive. CONCLUSIONS There is low to moderate evidence that interventions delivered via mHealth or eHealth approaches may be effective in increasing physical activity in older adults in the short term. Components of successful interventions include self-monitoring, incorporation of theory and behavior change techniques, and social and professional support.
