What is the ranking system for the EDSS scale for multiple sclerosis?

ANSWER

It ranges from 0 to 10. Lower numbers mean less disability, and higher numbers mean more.

  • 0: Normal
  • 1-1.5: No disability; abnormal neurological signs
  • 2-2.5: Minimal disability
  • 3-4.5: Moderate, but you can walk
  • 5-8: More severe, needing help walking
  • 8.5-9.5: Very severe, restricting you to bed
  • 10: Death

A 1-point change at the scale’s lower end reflects subtler changes than at the upper end. A one-point change between 2 and 3 is not as great a change in disability as between 8 and 9.
