Feasibility and Effectiveness of a Biography-Based Physical Activity Intervention in Institutionalized People With Dementia: Quantitative and Qualitative Results From a Randomized Controlled Trial.

The objective of this multicenter randomized controlled trial was to evaluate the feasibility and effectiveness of a physical activity intervention for institutionalized people with dementia, individualized by capacity and biography. The intervention group (n = 34; age: mean = 86.09 years; 79.40% female; mean Mini-Mental State Examination value = 18.59) participated in a multicomponent training program, which included daily activities, dancing, gardening, and sports/games, twice weekly for 3 months. The control group (n = 29; age: mean = 86.34 years; 75.90% female; mean Mini-Mental State Examination value = 19.90) received standard care. Feasibility was evaluated by means of focus groups and feedback questionnaires. Functional performance (Short Physical Performance Battery and Timed Up and Go Test), activities of daily living, and gait were outcomes for effectiveness. A high adherence rate (80.46%) and uniformly positive feedback indicate that the piloted training program is feasible. The results show preliminary effectiveness on functional performance (Short Physical Performance Battery mean t0 = 3.15; mean t1 = 4.50; p = .006) and gait (e.g., velocity mean t0 = 46.97; mean t1 = 58.04; p = .007).
