Modified Rankin Scale Calculator
Bounded offline reference: ModifiedRankinScalegrades describe global functional disability within a specified clinical assessment, not a summative item questionnaire. Source: ModifiedRankinScalestandard descriptions. Definition lookup does not assign a grade, validate interview reliability or predict outcome. Explicit topic keys: 0, 1, 2, 3, 4, 5, 6. Not a full/current corpus, diagnosis, treatment recommendation or safety certification.
Description
The modified Rankin scale describes recorded functional disability categories.
The modified Rankin scale describes recorded functional disability categories.1
Looking up a category definition does not determine a person's category.
When to use Modified Rankin Scale Calculator
Use this tool to read a bounded explanation for an exact reference topic. Establish the assessment or recording protocol, units, instrument version and independently applicable reference or calibration.
How to use Modified Rankin Scale Calculator and understand its results
- Establish the assessment or recording protocol, units, instrument version and independently applicable reference or calibration.
- Enter topic, using the field meanings and rules below, then run the tool.
- Read result.text. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| topic | Topic | string | Required |
Choose one exact topic token from the table. The implementation looks up the stored value and returns it in the documented output field. Matching is case-sensitive; unrecognized tokens fail. This is an offline bounded reference, not a live catalogue or independent attribution.
| Topic token | Stored value |
|---|---|
| 0 | No symptoms. |
| 1 | No significant disability despite symptoms; able to carry out usual duties/activities. |
| 2 | Slight disability; unable to carry out all previous activities but able to look after own affairs without assistance. |
| 3 | Moderate disability; requiring some help but able to walk without assistance. |
| 4 | Moderately severe disability; unable to walk or attend bodily needs without assistance. |
| 5 | Severe disability; bedridden, incontinent and requiring constant nursing care/attention. |
| 6 | Death recorded under the stated scale, not determined by this lookup. |
value=referenceTable[exactToken] Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.text | Text | string |
{
"input": {
"topic": "0"
},
"output": {
"result": {
"text": "No symptoms."
}
}
}Limitations and assumptions
Actual acquisition, assessment protocol, instrument version and calibration determine applicability. The tool does not examine a person, classify images, administer a questionnaire or choose diagnostic cutoffs.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use UPDRS Total Calculator: An UPDRS total combines independently coded section totals from a declared version. For a complementary comparison, use Expanded Disability Status Scale Calculator: EDSS interpretation depends on the applicable disability-assessment framework and recorded examination.
