Official title: Design, Development, and Validation of FEXO: A Playful-Recreational Exercise Intervention for Institutionalized Frail Older Adults to Improve Intrinsic Functional and Cognitive Capacity: A Randomized Controlled Trial

This multicenter randomized controlled trial aims to evaluate the effectiveness of a playful multicomponent exercise intervention (FEXO - Fun Exercise for Older Adults) on intrinsic capacity, frailty, and functional health in institutionalized older adults aged over 75. The FEXO program combines aerobic, strength, balance, and flexibility training in a recreational format. Participants will be randomized to an experimental group (receiving the 14-week FEXO program) or a wait-list control group (continuing daily routines). After the first intervention phase, the control group will also complete the program. Primary outcomes include improvements in intrinsic capacity domains (cognition, locomotion, vitality, sensory, and psychological), frailty phenotype (Fried criteria), and physical function.

Read the detailed description

Frailty is a dynamic syndrome marked by diminished physiological reserves and increased vulnerability to stressors. It is prevalent among institutionalized older adults and is associated with higher risks of dependency, hospitalization, and reduced quality of life. Evidence shows that physical inactivity and sedentary behavior significantly contribute to the onset and progression of frailty, especially in long-term care settings.

The World Health Organization (WHO) introduced the concept of Intrinsic Capacity in 2015, emphasizing a multidimensional view of healthy aging that includes cognition, mobility, vitality, sensory function, and psychological well-being. Preserving or enhancing intrinsic capacity is critical to prolonging independence and life quality among older adults.

This trial assesses the effectiveness of the FEXO program, a playful multicomponent exercise intervention designed to enhance intrinsic capacity and reduce frailty in adults over 75 years of age residing in geriatric care centers of the Ballesol Group (Valencia and Alicante). The intervention combines aerobic, strength, balance, gait, and flexibility exercises delivered in a recreational and group-based format using playful tools (e.g., foam balls, scarves, bubbles). Participants will engage in three 55-60 minute sessions per week over 14 weeks.

The study follows a wait-list controlled randomized design. Participants will be randomized to one of two groups: (1) the experimental group, which receives the FEXO intervention immediately, and (2) the control group, which continues routine activities during the first 14 weeks, followed by delayed participation in the program. Outcomes will be measured at baseline (T0), post-intervention (T1, at 14 weeks), and follow-up (T2, 28 weeks post-baseline for the control group).

Primary and secondary outcomes include: Fried's Frailty Phenotype, Short Physical Performance Battery (SPPB), Timed Up and Go Test (TUG), grip strength (JAMAR), walking speed (10-MWT), cognitive status (MMSE), nutritional status (MNA), depressive symptoms (GDS, CSDD), balance (Berg Balance Scale), and quality of life indicators.

This trial responds to the need for evidence-based interventions in institutionalized elderly populations, supporting WHO guidelines for healthy aging and promoting holistic care by integrating physical activity into daily routines through enjoyable, motivating formats.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intrinsic Capacity (IC)

    This composite outcome evaluates changes in intrinsic capacity, following the five-domain model proposed by the World Health Organization: cognition, vitality, locomotion (function), sensory function, and psychological well-being. Each domain is assessed through one standardized test: the Mini-Mental State Examination (MMSE) for cognition, the Mini Nutritional Assessment (MNA) for vitality, the Short Physical Performance Battery (SPPB) for locomotion, self-reported vision and hearing for sensory function, and the Cornell Scale for Depression in Dementia (CSDD) for psychological well-being. Each test contributes up to a maximum of 2 points, according to predefined cut-off values. For the cognitive domain (MMSE), 2 points are assigned if ≥27, 1 point if 10-26, and 0 points if 0-9. For vitality (MNA), 2 points are assigned if 24-30, 1 point if 17-23, and 0 points if <17. For locomotion (SPPB), 2 points are assigned if ≥10, 1 point if 3-9, and 0 points if 0-2. For sensory function (self-r

    Measured: Before and inmediately after the intervention

  2. Frailty (Fried's Phenotype)

    Frailty status will be assessed using Fried's phenotype, which classifies participants as robust (0 criteria), pre-frail (1-2 criteria), or frail (3-5 criteria) based on five components: unintentional weight loss, exhaustion, low physical activity, slow gait speed, and weak grip strength. Improvement is defined as transition to a lower frailty category (e.g., from frail to pre-frail).

    Measured: Before and inmediately after the intervention

Secondary outcomes (12)
  1. Short Physical Performance Battery (SPPB)

    The SPPB evaluates lower-extremity function through three subtests: standing balance (performed with feet together, semi-tandem, and tandem), gait speed over a 4-meter distance, and a five-times sit-to-stand test. Each subtest is scored from 0 to 4, for a total score ranging from 0 to 12. Higher scores indicate better physical performance. The SPPB is predictive of disability, hospitalization, and mortality in older adults.

    Measured: Before and inmediately after the intervention

  2. Timed Up and Go Test (TUG)

    This test assesses functional mobility and risk of falling. Participants are instructed to rise from a standard chair, walk 3 meters, turn around, walk back, and sit down. The total time (in seconds) is recorded. Lower times indicate better mobility and balance. The TUG has high predictive value for fall risk in frail older populations.

    Measured: Before and inmediately after the intervention

  3. Grip Strength (JAMAR Dynamometer)

    Grip strength will be measured using a JAMAR hand dynamometer, with participants seated, the elbow at 90°, forearm in a neutral position, and wrist slightly extended. The best of three trials is recorded in kilograms. Grip strength is a core indicator of sarcopenia and a strong predictor of functional decline, morbidity, and mortality. Higher values reflect better upper-limb muscle strength.

    Measured: Before and inmediately after the intervention

  4. 10-Meter Walk Test (10-MWT)

    Participants will perform two walking trials over 10 meters: one at habitual pace and one at maximum pace. The time to walk the central 6-meter portion is recorded and converted into meters per second (m/s). Gait speed is a validated marker of frailty, physical function, and fall risk. Higher walking speeds reflect better functional status.

    Measured: Before and inmediately after the intervention

  5. Mini-Mental State Examination (MMSE)

    The MMSE evaluates general cognitive status through domains including orientation, memory, attention, language, and visuospatial skills. It yields a score from 0 to 30, with higher scores indicating better cognitive function. It is widely used for screening and monitoring cognitive impairment in older adults.

    Measured: Before and inmediately after the intervention

  6. Mini Nutritional Assessment (MNA)

    The MNA is a validated tool for detecting malnutrition or risk of malnutrition in older adults. It includes 18 items covering anthropometry, general health, dietary intake, and subjective assessment. Total scores range from 0 to 30: scores ≥24 indicate normal nutrition, 17-23.5 suggest risk of malnutrition, and <17 indicate malnutrition. Higher scores reflect better nutritional status.

    Measured: Before and inmediately after the intervention

  7. Geriatric Depression Scale (GDS)

    The GDS short form (15 items) will be used to screen for depressive symptoms in participants. Responses are binary (yes/no), and total scores are calculated. Higher scores indicate more depressive symptoms; scores >5 may indicate clinical depression. Lower scores represent better psychological well-being.

    Measured: Before and inmediately after the intervention

  8. Berg Balance Scale (BBS)

    This 14-item scale assesses balance and postural control in older adults. Each task (e.g., standing, reaching, turning) is scored from 0 (unable) to 4 (independent), with a total score ranging from 0 to 56. Scores below 45 suggest increased fall risk. Higher scores reflect better balance.

    Measured: Before and inmediately after the intervention

  9. Barthel Index

    This scale measures independence in 10 basic activities of daily living (ADLs), including feeding, grooming, bathing, dressing, bowel and bladder control, toilet use, transfers, mobility, and stair use. Scores range from 0 to 100, with higher scores indicating greater functional independence. The index is commonly used in geriatric and rehabilitation settings.

    Measured: Before and inmediately after the intervention

  10. Cornell Scale for Depression in Dementia

    The Cornell Scale for Depression in Dementia (CSDD) will be used to assess depressive symptoms in participants with or without cognitive impairment. The scale consists of 19 items covering mood-related signs, behavioral disturbances, physical signs, cyclic functions, and ideational disturbances. Each item is rated from 0 to 2 (0 = absent, 1 = mild or intermittent, 2 = severe), based on interviews with both the patient and an informant. Total scores range from 0 to 38, with higher scores indicating more severe depressive symptoms. Scores above 10 suggest probable major depression, while scores above 18 are highly indicative of a depressive disorder. Lower scores represent better psychological well-being.

    Measured: Before and inmediately after the intervention

  11. Self-reported Vision

    Self-reported vision will be assessed through a single-item question asking participants to rate their visual ability. Responses are scored as follows: 0 = severe difficulty or complete blindness, 0.5 = mild to moderate difficulty, and 1 = no difficulty. Higher scores indicate better sensory function.

    Measured: Before and inmediately after the intervention

  12. Self-reported Hearing

    Self-reported hearing will be assessed through a single-item question asking participants to rate their hearing ability. Responses are scored as follows: 0 = severe difficulty or complete deafness, 0.5 = mild to moderate difficulty, and 1 = no difficulty. Higher scores indicate better sensory function.

    Measured: Before and inmediately after the intervention
