The EDSS score ranges from 0 to 10 and is based on your neurologist’s assessment of your ability and function. You are given a score when the initial diagnosis of MS is made, which is used as a reference for future evaluations.
Results may vary and are dependent on test conditions:
1-Day to day testing variability
2-Morning vs. afternoon testing
3-Doctor performing the test
4-Individual’s ability to walk on their own
5-The specific test performed in the doctor’s office (walking on heels, squeezing doctor’s hands, touching your nose while touching doctor’s finger, reflexes with hammer, etc.)
The EDSS score may also be used for medical insurance purposes to determine coverage for MS medications.
The course of MS is different for everyone; therefore, not everyone spends the same amount of time at each stage of the EDSS. As well, many people will remain at a certain level of ability without necessarily progressing to the next level.
