MSFC: Multiple Sclerosis Functional Composite

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.
