Functional Changes and Fall Risk in Older Adults Participating in a Frailty Program (FRAIL-ALAMA)

30. dubna 2026 aktualizováno: Lorenzo Antonio Justo Cousino, PhD, University of Vigo

Observational Study of Functional Changes and Fall Risk in Older Adults Participating in a Multicomponent Frailty and Falls Prevention Program in Primary Care

This prospective observational study aims to describe changes in physical function and fall risk in adults aged 70 years and older participating in a routine multicomponent frailty and falls prevention program in primary care. Participants are evaluated before and after the intervention, and additional postural control variables are recorded using a pressure platform without modifying routine clinical care.

Detailní popis

Frailty is a clinical condition associated with increased vulnerability to adverse health outcomes, including falls, disability, and mortality. In the Galician public health system, a structured frailty and falls prevention program is implemented within primary care physiotherapy services.

This study is designed as a prospective, longitudinal observational study with pre-post evaluation under real-world clinical conditions, without modifying clinical decision-making or healthcare organization.

Participants aged 70 years and older enrolled in the routine program undergo baseline (T0) and post-intervention (T1) assessments after 8 weeks. The intervention consists of a multicomponent exercise program including strength, balance, and functional training.

The primary objective is to describe changes in physical function and fall risk. Secondary objectives include the characterization of participants, analysis of adherence, recording of adverse events, and evaluation of the feasibility and utility of pressure-platform-based balance assessment.

Additional functional variables (muscle strength, aerobic capacity, and clinical balance tests) are included as part of the standardized functional assessment protocol implemented in routine care.

Studijní populace

The study population consists of older adults aged 70 years and above who are currently enrolled in the frailty prevention program within the Galician public health system. These individuals have been identified as frail or pre-frail through routine primary care screening and demonstrate sufficient functional capacity, as indicated by a Barthel Index score of 90 or higher, reflecting independence in basic activities of daily living.

Eligible participants must be able to understand the study procedures and provide informed consent, ensuring that they can engage safely and meaningfully in the intervention. All participants are actively involved in the structured frailty program delivered by primary care physiotherapy services, which focuses on preventing functional decline and reducing the risk of falls.

Individuals will be excluded if they present with any medical contraindication to exercise.

Popis opatření
Časové okno
Change in Physical Performance Short Physical Performance Battery (SPPB)
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

Change in Short Physical Performance Battery (SPPB) total score. The SPPB is a composite measure of lower extremity function including balance, gait speed, and chair stand tests.

  • Score range: 0 to 12
  • Interpretation: Higher scores indicate better physical performance
  • Unit of measure: Points on a scale
Baseline (T0) and post-intervention (8-12 weeks)
Change in Fall Risk
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

Change in fall risk indicators based on clinical assessment (falls history and gait impairment).

Minimum value: 0 Maximum value: Not applicable (composite clinical indicator; upper bound not fixed) Interpretation: Higher values indicate worse outcome (greater fall risk)
Baseline (T0) and post-intervention (8-12 weeks)
Change in Instrumented Balance: Center of Pressure (CoP) Sway Area
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

-Change in Center of Pressure (CoP) Sway Area

Change in postural sway area measured using a pressure platform. The Center of Pressure (CoP) sway area represents the area covered by the CoP trajectory during quiet standing.

Unit of measure: square millimeters (mm²). Higher values indicate worse postural stability.

Minimum value: 0 mm² Maximum value: Not applicable (no fixed upper limit) Interpretation: Higher values indicate worse postural stability
Baseline (T0) and post-intervention (8-12 weeks)
Change in Instrumented Balance: Center of Pressure (CoP) Velocity
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

Change in Center of Pressure (CoP) Velocity Change in mean velocity of center of pressure displacement.

• Unit of measure: mm/s

Minimum value: 0 mm/s Maximum value: Not applicable (no fixed upper limit) Interpretation: Higher values indicate worse postural stability

Časové okno
Functional Performance: Change in Timed Up and Go (TUG) Test
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

Time required to stand up, walk 3 meters, turn, return, and sit down.

  • Unit of measure: Seconds
  • Interpretation: Lower values indicate better performance

The interpretation of TUG results depends on the population (healthy adults, older adults, clinical populations), but general reference thresholds are as follows:

  • Older Adults (Community-Dwelling) < 12 seconds: Normal functional mobility 12-20 seconds: Mild impairment / increased risk of functional decline > 20 seconds: Significant mobility impairment
  • Fall Risk Interpretation > 13.5 seconds: Increased risk of falls (commonly used cut-off)

Clinical Populations (frail patients) 20-30 seconds: Moderate functional limitation > 30 seconds: Severe dependency in mobility

A change of approximately ≥ 2-3 seconds is often considered clinically meaningful, depending on the population studied.
Baseline (T0) and post-intervention (8-12 weeks)
Functional Performance: Change in Gait Speed (4-Meter Walk Test)
Časové okno: Baseline (T0) and post-intervention (8-12 weeks)

Only gait speed is reported as the outcome measure. Unit of measure: meters per second (m/s). Higher values indicate better functional performance.

Minimum value: 0 m/s Maximum value: Not applicable (no fixed upper limit; typically < 2.5 m/s in adults) Interpretation: Higher values indicate better functional performance
