mEGOS (GBS walking-outcome score)
Modified Erasmus GBS Outcome Score (Walgaard 2011): predicts the probability of being unable to walk unaided at 4 and 26 weeks, from age, preceding diarrhea, and the MRC sum score, scored at admission (0-9) or day 7 (0-12).

Example
- Age band
- Over 60 (+2)
- Preceding diarrhea
- Yes
- Assessment time point
- At day 7 / week 1 (MRC band weighted 0/3/6/9)
- MRC sum score band
- 30 or below
Result: mEGOS 12/12 (at day 7): a high score within the published 0-12 range; a higher score means a higher probability of being unable to walk unaided at 4 and 26 weeks.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Outcome
- a higher score means a higher probability of being unable to walk unaided at 4 and 26 weeks; the per-score probability is published only as curves, so this tool reports a relative reading.
What you enter
- Age band (<=40 / 41-60 / >60)
- Preceding diarrhea
- Assessment time point
- MRC sum score band
How this is calculated
- Components
- age (<= 40 0, 41-60 1, > 60 2), preceding diarrhea (+1), and MRC sum-score band weighted by timing (admission 0/2/4/6 -> 0-9; day 7 0/3/6/9 -> 0-12).
