EDSS scale...

The Kurtzke Expanded Disability Status Scale (EDSS) is a method of quantifying disability in multiple sclerosis.
The EDSS quantifies disability in eight Functional Systems (FS) and allows neurologists to assign a Functional System Score (FSS) in each of these.

0.0: Normal Neurological Exam

1.0: No disability, minimal signs on 1 FS

1.5: No disability, minimal signs on 2 of 7 FS

2.0: Minimal disability in 1 of 7 FS

2.5: Minimal disability in 2 FS

3.0: Moderate disability in 1 FS; or mild disability in 3 - 4 FS, though fully ambulatory

3.5: Fully ambulatory but with moderate disability in 1 FS and mild disability in 1 or 2 FS;
or moderate disability in 2 FS; or mild disability in 5 FS

4.0: Fully ambulatory without aid, up and about 12hrs a day despite relatively severe disability. Able to walk without aid 500 meters

4.5: Fully ambulatory without aid, up and about much of day, able to work a full day, may otherwise have some limitations of full
activity or require minimal assistance. Relatively severe disability. Able to walk without aid 300 meters

5.0: Ambulatory without aid for about 200 meters. Disability impairs full daily activities

5.5: Ambulatory for 100 meters, disability precludes full daily activities

6.0: Intermittent or unilateral constant assistance (cane, crutch or brace) required to walk 100 meters with or without resting

6.5: Constant bilateral support (cane, crutch or braces) required to walk 20 meters without resting

7.0: Unable to walk beyond 5 meters even with aid, essentially restricted to wheelchair, wheels self, transfers alone; active in
wheelchair about 12 hours a day

7.5: Unable to take more than a few steps, restricted to wheelchair, may need aid to transfer; wheels self, but may require
motorized chair for full day's activities

8.0: Essentially restricted to bed, chair, or wheelchair, but may be out of bed much of day; retains self care functions,
generally effective use of arms

8.5: Essentially restricted to bed much of day, some effective use of arms, retains some self care functions

9.0: Helpless bed patient, can communicate and eat

9.5: Unable to communicate effectively or eat/swallow
