When to use
Standard outcome measure in stroke care and trials.
How it works
0 no symptoms … 5 severe disability … 6 dead. 0–2 = functional independence.
Key points
- 0–2 is a favourable, independent outcome.
- Use a structured interview for reliability.
- The primary endpoint in many stroke trials.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Disability level | 0 — No symptoms |
|---|
→mRS0/6
- Functional outcome：Functionally independent (favourable outcome).
| Disability level | 6 — Dead |
|---|
→mRS6/6
- Functional outcome：Dependent or worse.
