Combined Exercise and Cognitive Stimulation for Falls Prevention

Usual care: subjects randomized to the usual care group will receive an evidence-based multidisciplinary intervention tailored at reducing the fall risk (polypharmacy, environmental intervention, physical exercise). Importantly, the Otago exercise program (considered the standard physical exercise intervention) will be prescribed in this group. Intervention group: subjects assigned to this intervention will engage in a multicomponent intervention combining an exercise program, Vivifrail (A practical guide for prescribing a Multicomponent Physical Training Program to prevent weakness and falls in people over 70, more information at www.vivifrail.com) and a cognitive training. Vivifrail exercise program combines resistance, endurance, balance and flexibility exercise tailored to the functional level of the subjects, guaranteeing an individualized approach. Exercises progress in terms of intensity and difficulty as the subject adapts to exercise. The cognitive stimulation program combines exercises to work on different cognitive functions, mainly addressing executive functions (attentional system, processing speed, perceptual organization, working memory and cognitive flexibility, verbal comprehension, abstraction and reasoning, planning, execution and problem solving ). It lasts 12 weeks, two weekly sessions. It is divided into 4 levels in order to adapt the intervention to participant's individual capacity, and the level can be adjusted throughout the intervention. Correct execution will be monitored by constant contact with relatives in charge of supervising the exercise program, who will be familiarized with the intervention prior to participation.
