Feasibility and usability evaluation of a gamified fatigue management mobile application for persons with multiple sclerosis in everyday life.

Background: Fatigue is the most debilitating and prevalent symptom of multiple sclerosis (MS), affecting up to 80 % of patients and significantly impairing quality of life (QoL). Managing MS fatigue is challenging due to its multifactorial nature, encompassing physical, cognitive, and psychosocial components. Mobile health (mHealth) tools offer promising approaches for self-management, but most lack personalization and rigorous validation.
