Clinical Disease Activity With Long Term Natalizumab Treatment
Relapsing-Remitting Multiple SclerosisThe primary objective of the study is to retrospectively investigate the proportion of participants free of new or enlarging fluid-attenuated inversion recovery (FLAIR) lesions over time in approximately 300 Relapsing-Remitting Multiple Sclerosis (RRMS) participants with regular MRI follow-up, who have received natalizumab ≥24 month from two different observational cohorts: 1) approximately 230 participants from the Czech Republic; and 2) approximately 70 participants from Belgium. The secondary objectives of this study are as follows: Brain volume change by various measures; Changes in the number and volume of magnetic resonance imaging (MRI) lesions; No evidence of disease activity (NEDA) with and without brain volume change.

Role of Neuromuscular Junction Function in Motor Fatigue in Multiple Sclerosis
Multiple SclerosisThis pilot study will evaluate for the presence of neuromuscular junction (NMJ) defect in women with motor fatigue in multiple sclerosis by Single Fiber Electromyography (SFEMG) using the concentric needle electrode.

Multicenter Validation of The Evergreen Myometric Strength Test for Lower Extremities (EMST-LE)...
Multiple SclerosisA Cross- Sectional study; To assess the intra-rater and inter-rater reliability of a hand-held dynamometer (HHD) in the assessment of lower extremity strength in patients with multiple sclerosis

Characterizing Upper Extremity Function in Individuals With Multiple Sclerosis
Multiple SclerosisUpper extremity (UE) function is critical to maintaining independence. Better understanding of UE involvement in MS will provide necessary information to prioritize the design and selection of future interventions. The goal of the proposed project is to characterize UE involvement in a population of community-based persons with MS across the International Classification of Functioning, Disability & Health (ICF) domains and constructs.

Improved Detection of Multiple Sclerosis Plaques in Inversion Recovery by Optimization of Sequence...
Multiple SclerosisThis study evaluates different optimized MRI sequences for the detection of brain lesions in patients with multiple sclerosis in comparison with the recommended FLAIR sequence

Electrophysiological Study of Spatiotemporal Gait Parameters in Patients in Early Stage of Multiple...
Multiple Sclerosis35 patients with multiple sclerosis have been enrolled in a previous study to record and analyze gait parameters. This study aims to enroll gender and and matched healthy subjects for a control group, to compare patients' gait parameters with healthy subjects'.

Non-interventional Study to Assess Adherence to Treatment for Patients With RMS (MAIN-MS)
Relapsing Multiple Sclerosis (RMS)This is an open label, non randomized, uncontrolled, multicenter, single arm observational study. In this study, the enrolled subjects will be treated with Rebif human serum albumin (HSA)-free formulation (with or without RebiSmart) 44 microgram (mcg), subcutaneous (sc), thrice in a week (tiw) for 24 months.

Rehabilitation in Multiple Sclerosis - Sometimes Too Much?
Multiple SclerosisThe primary objective is to evaluate changes in fatigue and physical activity (step counts) before and after rehabilitation in patients with MS (EDSS 3-6.5). The association of changes in fatigue and physical activity will also be analyzed for disease severity (EDSS), age, emotional status (depression) of the participants.

BETAEVAL Global - The New BETACONNECT Auto-injector : Adherence and EVALuation of Multiple Sclerosis...
Multiple SclerosisRelapsing RemittingConsidering the significance of an early and consequent Multiple Sclerosis (MS) treatment as well as the challenge to achieve high adherence to treatment, evaluating the benefits of any new measure to improve adherence is important. The data storage capabilities of the BETACONNECT device, including the automated recording of injections, will facilitate the collection of reliable data on patient's injection behavior and adherence, which should be unaffected by recall bias or reporting bias. To better understand the utilities of the new BETACONNECT device and characterize its contribution to adherence, we plan to prospectively follow-up MS patients using this device for 24 weeks. The study will take place in a real-life setting in Neurology centers across Europe.

An Observational, Retrospective, UK & Ireland Audit of Patient Adherence to Rebif® Injections Using...
Relapsing Multiple SclerosisThis is an observational, retrospective, UK & Ireland audit measuring patient adherence to Rebif® injections with the RebiSmart™ injection device. Data will be collected from Multiple Sclerosis (MS) patients who have been prescribed Rebif® and have been using the RebiSmart™ device for injection for a minimum of 24 months.
