The EDSS is a scoring system for quantifying the impairment brought on by MS. It includes measurements assessing weakness of limbs, tremor, speech and swallowing difficulties, numbness, bowel and bladder function and visual function amongst others. It is a scale from 0 to 10, where 0 = no impairment, 10 = the greatest severity.
