Expanded Disability Status Scale

From WikiMD's Food, Medicine & Wellnesspedia

Expanded Disability Status Scale (EDSS) is a method of quantifying disability in Multiple Sclerosis and monitoring changes in the level of disability over time. It is widely used in clinical trials and in the assessment of people with MS.

Overview[edit | edit source]

The EDSS scale ranges from 0 to 10 in 0.5 unit increments that represent higher levels of disability. Scoring is based on an examination by a neurologist.

Scale[edit | edit source]
