Worldwide longitudinal observational study of fatigue- related symptoms in patients with relapsing multiple sclerosis, daily assessment and 7-day lookback

Fatigue is one of the most common symptoms of multiple sclerosis (MS). Using MS-specific patient reported outcomes to characterize it would grant a better understanding of its impact on patients’ quality of life (QoL).
This observational longitudinal study aimed to measure fatigue in Relapsing MS (RMS) patients from multiple countries using the Fatigue Symptoms and its Impacts Questionnaire-RMS (FSIQ-RMS).
