Sintesi	The EDSS is the most widely used clinical disability rating scale in multiple sclerosis research and practice. Developed by John Kurtzke in 1983, it provides a 0-10 ordinal scale capturing disease severity across eight neurological functional systems and functional status. The EDSS remains the primary endpoint in MS clinical trials and longitudinal cohort studies, with decades of prognostic and comparative data worldwide.	The Multiple Sclerosis Functional Composite (MSFC) is an objective, performance-based assessment of MS-related disability capturing three key functional domains: lower extremity mobility, upper extremity coordination, and cognitive/processing speed. Developed in 1999 by the National MS Society and adopted widely in clinical trials, the MSFC provides quantifiable endpoints complementing the Expanded Disability Status Scale (EDSS). The three-component design addresses EDSS limitations by including cognition and standardizing measurement via timed tasks.	The NIHSS is the standard acute stroke severity assessment tool used in emergency departments, stroke centers, and clinical trials worldwide. Developed by the NIH Stroke Study Group in 1989, the 15-item scale provides rapid, reproducible quantification of acute neurological deficit from ischemic or hemorrhagic stroke. NIHSS scores inform thrombolytic and thrombectomy eligibility, predict outcomes, and serve as primary endpoint in stroke intervention trials.	The Rivermead Mobility Index (RMI) is a brief, clinician-observed performance test of basic mobility abilities developed for assessing stroke and neurological rehabilitation outcomes. Published in 1991 by Frank Collen and colleagues at Rivermead Rehabilitation Centre (Oxford, UK), the 15-item index measures bed mobility, sitting/standing balance, transfers, and ambulation. The RMI is widely used in stroke units and rehabilitation settings to track functional recovery and predict discharge outcomes.
