Graded Cognitive Load and How It Affects Mobility in Older Adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study examines dose-response and phase-specific effects of graded cognitive load on functional mobility in older adults. Using a dual-task cognitive loading protocol, researchers will observe how increasing cognitive demand during movement impacts gait and mobility metrics. Participants will be adults aged 60 years or older who can ambulate independently, have normal cognitive screening, and meet functional independence criteria. The study will employ kinematic analysis to quantify movement performance under varying cognitive loads. The goal is to understand whether higher cognitive demands produce graded deterioration in motor performance, informing rehabilitation and fall-risk assessment.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Age ≥ 60 years
* Ability to ambulate independently without assistive devices
* Ability to follow verbal instructions and perform dual-task activities
* Medically stable and capable of participating in functional mobility assessment Cognitive function within normal range, defined as Mini-Mental State Examination (MMSE) score ≥ 24 out of 30, indicating absence of significant cognitive impairment .
* Functionqal independence in basic activities of daily living, defined as Barthel Index score ≥ 90 out of 100
* Body Mass Index (BMI) between 18.5 and 29.9 kg/m², as values ≥ 30 kg/m² (obesity) may adversely affect gait and balance performance.

Exclusion Criteria:

* Any neurological disease that affects walking or balance, such as stroke or Parkinson's disease
* Any musculoskeletal condition that limits lower-limb movement or affects normal walking patterns
* Severe cognitive impairment defined as Mini-Mental State Examination (MMSE) score \< 24
* Visual, vestibular, or hearing problems that affect safe walking or balance control
* History of lower-limb injury or surgery within the last 6 months
* Serious medical conditions that make participation unsafe, such as unstable cardiac or respiratory disease
