-Summary
This study aims to investigate the effects of cognitive load on gait and balance performance in individuals with Motoric Cognitive Risk Syndrome (MCRS). Participants will perform Timed Up and Go (TUG) and tandem walking tests under single-task and dual-task conditions. The study evaluates cognitive-motor interference and dual-task cost to better understand early markers of cognitive decline and fall risk.

| Motoric Cognitive Risk Syndrome Group | | Other: Assessment Protocol | Community-dwelling older adults aged 65 years and above diagnosed with Motoric Cognitive Risk Syndrome will be included. Participants will perform Timed Up and Go (TUG) and tandem walking tests under single-task and dual-task conditions. No intervention will be applied. |
- Assessment Protocol (Other): Participants will undergo standardized Timed Up and Go (TUG) and tandem walking assessments under single-task and dual-task conditions. Cognitive dual-task conditions will include serial subtraction while performing the motor task. No therapeutic intervention, exercise training, or treatment will be applied.
+Outcome measures
Primary outcomes
- Timed Up and Go (TUG) performance [Baseline (single session assessment)]: Functional mobility will be assessed using the Timed Up and Go (TUG) test. Participants will stand up from a standard chair (approximately 46 cm), walk 3 meters, turn around a marker, return, and sit down. Performance time will be recorded in seconds under three conditions:
single-task (baseline), physical dual-task (carrying a cup of water), and cognitive dual-task (serial subtraction task).
Secondary outcomes
- Tandem walking test performance [Baseline]: Static and dynamic balance will be assessed using tandem walking. Participants will walk in a heel-to-toe position under two conditions:
single-task, cognitive dual-task (serial subtraction). Performance time will be recorded in seconds.
- Dual-task cost (%) [Baseline]: Dual-task cost will be calculated to quantify the decline in performance under dual-task conditions compared to single-task performance. It will be expressed as a percentage using standard formulas for both TUG and tandem tests.
- Gait speed [Baseline]: Walking speed will be derived from the TUG test and expressed in meters per second (m/s) under single and dual-task conditions.
- Cognitive-motor interference [Baseline]: Performance deterioration during dual-task conditions will be evaluated to assess cognitive-motor interference effects in individuals with Motoric Cognitive Risk Syndrome.
