This study aims to evaluate the feasibility of a 12-week individualised home-based Otago Exercise Program (OEP) delivered through a hybrid model of physiotherapist face-to-face visits and telehealth sessions for community-dwelling older people living with dementia in Indonesia, and the preliminary effects of the program on mobility, balance, endurance, lower limb strength and sleep quality. This was pre-post intervention single group study with three assessment time-points (baseline, 12 and 18 weeks). Participants were 30 dyads of community-dwelling older people with dementia and their carers. Participants with dementia underwent a 12-week physiotherapist-delivered hybrid model exercise program, with informal carer supervision between supervised hybrid sessions, and continued the exercises for a further six weeks without physiotherapist supervision. The participant dyads and the physiotherapist delivering program were also surveyed after the program to explore their perception and experience of the exercise program. Thirty dyads of older people with dementia and their informal carers were recruited, five (16.67%) participants withdrew across the 12-week hybrid model supervised program. Median adherence to the exercise program was 80% (IQR (25, 75) = 71.6, 88.3) during the 12-week intervention, and 73.3% (IQR (25, 75) = 66.6, 80) in the self-maintenance period. No falls or adverse events were reported. Balance, lower limb strength, endurance and sleep quality improved significantly at 12 and 18 weeks compared to baseline. It can be concluded that the hybrid model of OEP was feasible and safe and may have benefits on health outcome of older people with dementia living in the community in Indonesia.
