This observational study aims to investigate the validity and reliability of the Figure-of-8 Walk Test (8FWT) in individuals with Motoric Cognitive Risk Syndrome (MCRS). The study will evaluate test-retest reliability, measurement error (SEM, MDC), and construct validity by examining the relationship between 8FWT performance and functional mobility measures. The findings are expected to provide evidence for the clinical applicability of 8FWT in assessing dynamic balance, gait performance, and cognitive-motor interaction in older adults.
