About

Randomized clinical trial of 310 older adults over 75 years old recruited from the Falls Units of Geriatric Departments in 4 three University Hospitals in Spain (Pamplona, San Sebastián, Albacete and Barcelona). Participants who met inclusion criteria will be randomized to the usual care group (Otago exercise program) or the Vivifrail-Cog Intervention (a combination of physical exercise Vivifrail program and cognitive training). The main objective of the present randomized clinical trial is to investigate the effect of the combined intervention (exercise and cognitive intervention) in frail older participants living in the community and at risk of falling. The main endpoint will be the rate of falling in the following year. Secondary endpoints include physical performance, muscle strength, cognitive performance, hospitalizations, institutionalization, depression and quality of life.

Full description

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.

Ages: 75+ years old

Combined multicomponent physical exercise and cognitive stimulation (Vivfrail-Cog)

Experimental group

Description:

The supervised multicomponent exercise training program (resistance, endurance, balance and flexibility) will be comprised of upper and lower body exercises tailored to the individual's functional capacity. Subjects will be encouraged at performing strength and endurance exercise at a moderate intensity. Exercise will progress in terms of intensity and difficulty upon individual adaptation. The cognitive intervention will include the performance of different exercises with pencil and paper in order to train different cognitive areas, especially the executive functions.

Treatment:

Other: Vivfrail-Cog combined multicomponent physical exercise and cognitive stimulation.

Usual care

No Intervention group

Description:

The usual care group will receive normal outpatient care (including the evidence-based Otago exercise program).
