Ashworth Spasticity Scale Calculator
Bounded offline reference: ModifiedAshworthgrading includes a distinct1+category and is an ordinal description of resistance during an independently assessed passive movement. Source: ModifiedAshworthScalestandard descriptions. Resistance is not uniquely neural spasticity; no automatic examination, arithmetic averaging or diagnosis. Explicit topic keys: 0, 1, 1+, 2, 3, 4. Not a full/current corpus, diagnosis, treatment recommendation or safety certification.
Description
The Modified Ashworth Scale describes ordinal resistance findings during passive movement.
The Modified Ashworth Scale describes ordinal resistance findings during passive movement.1
Category 1+ is a distinct token rather than a decimal score for arithmetic averaging.
When to use Ashworth Spasticity 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 Ashworth Spasticity 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 increase in muscle tone. |
| 1 | Slight increase with catch/release or minimal resistance at end of range. |
| 2 | More marked increase through most range, but part easily moved. |
| 3 | Considerable increase; passive movement difficult. |
| 4 | Part rigid in flexion or extension. |
| 1+ | Catch followed by minimal resistance through less than half the remaining range. |
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 |

}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.
