Observational study finds dual-task exacerbates postural instability in women with multiple sclerosis, suggesting fatigue influences balance performance.
Key Points
Fatigue and dual-task conditions significantly increased postural instability in women with MS.
MS patients exhibited higher medial-lateral COP displacements during dual-task compared to controls.
Weakened ankle plantar flexors' strength correlated with poorer balance performance only in fatigued MS patients.
Further investigation is needed to understand interactions between fatigue, attentional demands, and muscle strength.
