Relationship Between Single- and Dual-Task Obstacle Crossing Performance and Fatigue and Disability Levels in Patients With Relapsing-Remitting Multiple Sclerosis
This cross-sectional observational study aims to investigate the relationship between obstacle crossing performance under single-task and dual-task conditions and the levels of fatigue and disability in individuals with Relapsing-Remitting Multiple Sclerosis (RRMS). Walking performance will be assessed under standard walking and obstacle crossing conditions with and without a concurrent cognitive task. The study will examine how increased task complexity affects walking performance and its association with fatigue, disability, cognition, and functional mobility.
