- Brief Summary
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.
- Detailed 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.

Group Intervention Description Combined multicomponent physical exercise and cognitive stimulation (Vivfrail-Cog) Vivfrail-Cog combined multicomponent physical exercise and cognitive stimulation. 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.

One year fall-related fracture during one year Number of fall-related fracture (radiologically confirmed)
One year fall-related hospitalizations during one year Number of fall-related hospitalizations
One year fall-related death during one year Number of fall-related death
- Secondary Outcome Measures
Name Time Method Barthel At baseline, 6-week, 12-week and 24-week and 1-year. Barthel Index changes from baseline to 6-week, 12-week and 24-week and 1-year
Musculoskeletal echography At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. Muscle thickness and quality will be assessed through musculoskeletal echography, a non-intrusive imaging method. Muscle thickness and quality (infiltration of non-contractile tissue) will be measured in the rectus femoris (region from sub-cutaneous tissue to the bone surface).
MOCA (Montreal Cognitive Assessment) test At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. cognitive function will be measured with MOCA ( Montreal Cognitive Assessment Test) in case of mild cognitive decline. The MOCA is a validated test in Spanish It ranges from 0 ( worse score ) to 30 (best score). A score less than 26 indicates suggest mild cognitive decline
1-Repetition Maximum (RM) Maximal dynamic strength test At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. Maximal dynamic strength will be assessed using the 1Repetition Maximum (RM) test in the bilateral leg press exercise using exercise machines (Exercycle, S.L., BH Group, Vitoria, Spain). In the first assessment, the subjects will warm up with specific movements for the exercise test. Each subject's maximal load will be determined in no more than five attempts, with a 3-min recovery period between attempts
Geriatric Depression Scale (GDS) Yesavage abbreviated scale At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. Depression will be assessed wit the GDS Yesavage abbreviated scale of 15 items. Is is ranged between 0 ( best value) to 15 ( worse value). Scores between 0-5 indicates normality, 5-9 minor depression and scores over 9 indicates mayor depression
Psychotropic and hypotensive drugs registration At baseline and 3 months Registration of the presence of psychotropic and hypotensive drugs during follow -up will be done with a clinical questionnaire
Garvan Fracture Risk At baseline and 12-week Changes from baseline to 12-week The Fracture Risk Calculator was developed using data collected in the internationally renowned Dubbo Osteoporosis Epidemiology Study conducted by the Bone and Mineral Research Program of Sydney's Garvan Institute of Medical Research. It estimates the 5-year and 10-year risk of hip and any fracture based on information on sex, age, number of fractures since the age of 50, the rate of falling and the bone mineral density.
Short Physical Performance Battery (SPPB) At baseline,1 and 3 months. Changes from baseline to 1 and 3 months. The functional capacity of patients will be evaluated by the Short Physical Performance Battery (SPPB) which evaluates, balance, gait ability, and leg strength using a single tool. The total score ranges from 0 (worst) to 12 points (best). The SPPB test has been shown to be a valid instrument for screening frailty and predicting disability, institutionalization, and mortality. A total score of less than 10 indicates frailty and a high risk of disability and falls. A one-point change in the score has clinical relevance
Fried's Frailty Phenotype (FP) At baseline and 3 months Changes from baseline to 3 months. The Fried's Frailty Phenotype (FP) consists of five items: weight loss, exhaustion, strength, physical activity and gait speed. For grip strength, 3-m GS and Physical Activity Scale for the Elderly (PASE) scores. Subjects are classified as robust if not meeting any criteria, pre-frail if they met 1-2 of the criteria and frail if ≥3 were present.
SARC-F (Screening of Sarcopenia Among Older Adults) At baseline,1 and 3 months. Changes from baseline to 1 and 3 months. The SARC-F is a screening scale to ascertain the risk of sarcopenia (the presence of age-associated low muscle mass and function). It is composed of 5 items related to the presence of difficulty in loading weights, walking, standing-up from a chair, climbing stairs and the number of falls in the previous year. A score greater than 4 is indicative of the presence of sarcopenia.
Handgrip Strength in both hands At baseline, 6-week, 12-week Changes from baseline to 6-week and 12-week.Handgrip strength will be measured by using a dynamometer (JAMAR) in both dominant and non-dominant hand. Best performance of two trials will be registered.
4-metre gait velocity test (GVT) At baseline, 6 week and 3 months. Changes from baseline to 6 week and 3 months.Gait ability will be assessed using the 6-metre gait velocity test (GVT). Starting and ending limits will be marked on the floor with tapelines for a total distance of 8 meters. Participants will be instructed to walk in their self-selected usual pace for two attempts. The best result of both trials will be registered. The first and last metre, considered the warm-up and deceleration phases, respectively, will not be included in calculations of the gait assessment. Higher scores ( \> 1.0 m/s) indicates better functional capacity and lower scores (\< 0.8 m/s) scores worse functional capacity.
Presence of 5 or more drugs ( Polypharmacy ) registration At baseline and 3 months Registration of the presence of 5 or more drugs( Polypharmacy ) during follow -up will be done with a clinical questionnaire
Dual task gait (verbal) 6 m velocity test At baseline, 6-week and 3 months The dual-task paradigm will be used in the 6-m habitual GVT. Two trials will be conducted(best record will be taking in account)During the verbal dual-task condition (verbal GVT), we will assess gait velocity while participants are naming animals by loud
EuroQol-5D (EQ-5D) Quality of life assessment test At baseline and 3 months Quality of life will be assessed with an international validated scale EuroQol-5D (EQ-5D). Its composed by. It asses health status (mobility, personal care, basic and instrumental daily living activities , pain and ansiety/depression) ranged from 0 ( worst health status) to 100 ( best health status )
Trail Making Test part A ( TMT-A) At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. Executive function will be assessed with the Trail Making Test part A. Results for TMT A are reported as the number of seconds required to complete the task; therefore, higher scores reveal greater impairment.Average will be consider 29 seconds, Deficient \> 78 seconds and Rule of Thumb most 90 seconds
Falls-related psychological consequences At baseline, 12 week, 24 week and 1 year. Changes from baseline, 12-week visit; and 24-week and 1-year. Fear of falling will be evaluated through three questions: ''Are you afraid of falling?'', ''Do you limit any house-hold activities because you are frightened you may fall?'', ''Do you limit any outside activities because you are frightened you may fall?''.
FES-I was developed as part of the Prevention of Falls Network Europe (ProFaNE) project from 2003 to 2006, following an intensive review of fear of falling, self-efficacy and balance confidence questionnaires. It ascertains the impact that fear of falling has on 16 activities of daily living. Scores range from 16 to 64 and classify the fear of falling as low (16-19), moderate (20-27) and high (28-64) concern.Repetitions at maximal velocity at intensities of 50% of 1RM test At baseline, 6 weeks and 3 months Changes from baseline to 6-week and 3 months. Participants will perform ten repetitions at maximal velocity at intensities of 50% of 1RM to determine the maximum power (w) and the loss of power during the ten repetitions in the leg press exercise. Higher values indicate better functional capacity
