About this study

Official title: Neural, Cognitive, and Biomechanical Determinants of Falls in Older Adults: A Two-Phase Multimodal Investigation With a Phenotype-Guided Rehabilitation Trial

The goal of this clinical trial with an embedded observational phase is to evaluate whether a phenotype-guided, personalized rehabilitation program can improve fall risk and underlying neural control mechanisms in older adults aged ≥65 years, including both high and low fall-risk individuals.

The main questions it aims to answer are:

Read more

Do older adults at high fall risk exhibit altered neural, neurocognitive, and biomechanical profiles compared with low/no fall-risk individuals? Does personalized rehabilitation guided by neurophysiological and neurocognitive profiles result in greater reductions in fall risk and improvements in motor control compared with conventional rehabilitation?

Researchers will compare personalized phenotype-guided rehabilitation to conventional evidence-based fall-prevention exercise to determine whether targeted, mechanism-based intervention leads to superior clinical and mechanistic outcomes.

Participants will:

Undergo a comprehensive multimodal assessment including neurophysiological (EEG, EMG), neurocognitive (fNIRS, dual-task testing), and biomechanical (gait and balance) measures Be classified into fall-risk and neurophysiological control profiles based on assessment results (Phase 2 - high fall-risk participants only) be randomly assigned to either personalized rehabilitation or conventional rehabilitation Attend supervised exercise sessions 2-3 times per week for 8-12 weeks Complete gait, balance, and cognitive-motor assessments before and after the intervention Record falls prospectively using monthly fall diaries and follow-up monitoring over 3-6 months

Read the detailed description

Background:

Falls among older adults are a leading cause of injury, disability, and loss of independence worldwide. Despite the availability of exercise-based and multifactorial interventions, their effectiveness remains inconsistent, partly because current approaches do not adequately address the underlying mechanisms of instability. Emerging evidence suggests that fall risk arises from complex interactions between neural, cognitive, and biomechanical systems, with substantial heterogeneity in control strategies across individuals. This study aims to develop and evaluate a mechanism-based framework that integrates these domains to improve fall-risk assessment and guide personalized rehabilitation.

Objectives:

The primary objectives are: (1) to compare neural, neurocognitive, and biomechanical determinants of fall risk between older adults with high and low fall risk; and (2) to evaluate whether a personalized rehabilitation program guided by individual neurophysiological and neurocognitive profiles leads to greater reductions in fall risk and improvements in motor control compared with conventional rehabilitation.

Methods:

This study adopts a two-phase multimodal design. Phase 1 is a cross-sectional causal-comparative study involving approximately 80 community-dwelling older adults aged 65 years and above, classified as high or low fall risk. Participants will undergo comprehensive assessment of neural control, neurocognitive load, and functional performance using electroencephalography and electromyography, functional near-infrared spectroscopy during dual-task conditions, and quantitative gait and balance analysis. Phase 2 is a pilot randomized controlled trial involving high fall-risk participants, who will be allocated to either a personalized rehabilitation program guided by individual neurophysiological and neurocognitive profiles or a conventional evidence-based fall-prevention program. Both groups will receive supervised training for 8-12 weeks. Primary outcomes include feasibility measures and prospective fall events over 3-6 months. Secondary outcomes include changes in neural control, cognitive-motor integration, and biomechanical stability.

Discussion:

This study proposes a novel phenotype-guided approach to fall prevention that targets the underlying neural control mechanisms rather than general physical impairments. By integrating multimodal assessments with personalized intervention, the study has the potential to improve the precision and effectiveness of rehabilitation strategies. Findings will provide important insights into the mechanisms of fall risk and inform the design of larger clinical trials and future clinical practice.

Secondary outcomes (10)
  1. Number of Falls per Participant

    Description The total number of falls experienced by each participant during the follow-up period will be prospectively recorded using monthly fall diaries, structured telephone follow-up, and caregiver confirmation when applicable. A fall is defined as "an unexpected event in which the participant comes to rest on the ground, floor, or lower level." Unit of Measure Number of falls

    Measured: During the 3- to 6-month follow-up period after completion of the intervention.

  2. Time to First Fall

    Time from completion of the intervention to the first prospectively recorded fall will be measured using monthly fall diaries, structured telephone follow-up, and caregiver confirmation when applicable. A fall is defined as "an unexpected event in which the participant comes to rest on the ground, floor, or lower level." Unit of Measure Days (or Months, depending on your planned statistical analysis)

    Measured: During the 3- to 6-month follow-up period after completion of the intervention.

  3. Neurophysiological Outcomes (Corticomuscular Coherence (CMC))

    Primary metric:

    ΔCMCβ = CMCFoam EC - CMCFirm EO

    Outcomes:

    • Change in ΔCMCβ from baseline to post-intervention
    • Normalization of task-dependent cortical modulation Interpretation: Reflects changes in cortical involvement and neural efficiency in postural control.

    Measured: Phase 1 at baseline, post phase 2 intervention 8-12 weeks, and follow up 3-6 month

  4. Neurophysiological Outcomes (Intermuscular Coherence (IMC))

    Coordination of shared neural input between muscles assessed using intermuscular coherence.

    Primary metric:

    ΔIMCLF = IMCFoam EC - IMCFirm EO

    Outcomes:

    • Change in low-frequency IMC modulation
    • Improvement in coordination patterns Interpretation: Reflects reorganization of subcortical and intermuscular coordination mechanisms.

  5. Change in Prefrontal Oxygenated Hemoglobin Concentration During Dual-Task Walking

    Prefrontal cortical activation will be assessed using functional near-infrared spectroscopy. Oxygenated hemoglobin concentration will be recorded during single-task walking and dual-task walking. The outcome will be the dual-task-related change in oxygenated hemoglobin concentration, calculated as the mean oxygenated hemoglobin concentration during dual-task walking minus the mean oxygenated hemoglobin concentration during single-task walking. Results will be reported in micromoles per liter (µmol/L). A reduction in excessive dual-task-related prefrontal oxygenation after the intervention will be interpreted as improved neural efficiency, provided that walking and cognitive-task performance are maintained or improved.

    Measured: Baseline, immediately after completion of the 8-12-week intervention, and at the 3-6-month follow-up.

  6. Change in Global Walk Quality Index

    Overall gait quality will be assessed using the Global Walk Quality Index obtained from the Gait \& Balance App. The Global Walk Quality Index is a single unitless composite indicator integrating walking speed, step length, step time, gait symmetry, and gait variability. These gait parameters will be combined according to the predefined Global Walk Quality Index calculation method, and only the resulting composite score will be reported under this outcome measure. Change will be calculated from baseline to each post-baseline assessment.

    Measured: Baseline, immediately after completion of the 8-12-week intervention, and at the 3-6-month follow-up.

  7. Change in Overall Balance Stability Index

    Overall postural stability will be assessed using the ProKin Balance Platform under the foam eyes-closed condition. The Overall Balance Stability Index, generated by the ProKin software, will be used as the primary balance outcome. This composite index integrates anteroposterior and mediolateral postural sway into a single measure of overall balance performance. Lower values indicate better postural stability.

    Measured: Baseline, immediately after the 8-12-week intervention, and at the 3-6-month follow-up.

  8. Timed Up and Go Test Completion Time

    Functional mobility will be assessed using the Timed Up and Go (TUG) test. The time required to stand from a standard chair, walk 3 meters, turn, return, and sit down will be recorded.

    Unit Seconds

    Measured: Baseline, post-intervention, and 3-6-month follow-up.

  9. Berg Balance Scale Total Score

    Balance performance will be assessed using the Berg Balance Scale (BBS). The total score ranges from 0 to 56, with higher scores indicating better balance performance.

    Unit Total score (0-56)

    Measured: Baseline, post-intervention, and 3-6-month follow-up.

  10. Functional Reach Test Distance

    Dynamic balance will be assessed using the Functional Reach Test (FRT). The maximum forward reach distance while maintaining a fixed base of support will be measured.

    Unit Centimeters

    Measured: Baseline, post-intervention, and 3-6-month follow-up.
