Description
Interpolate an explicit goal-anchor map without supplying a clinical scale.
Movement research distinguishes elapsed time, active time, cycle phase, measured force, and assessment-score conventions. Normalizing or remapping these quantities can help compare records when their units and definitions agree. A local arithmetic term does not by itself validate a functional assessment or an exercise program.
Interpolate an explicit goal-anchor map without supplying a clinical scale.
When to use this tool
Use Rehabilitation Goal Attainment Anchor Map when you need this motion, timing, force, annotation, or score-mapping component for supplied research records.
How to use the tool and how it works
- Enter score, anchors, mapped. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read mappedScore, interval. Use the output convention below.
Require aligned anchors and mapped arrays with at least two strictly increasing anchors and score within their range. Find the first interval whose upper anchor is at least score, interpolate mappedScore linearly, and return its zero-based interval.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| score | Score | Required. Finite number. |
| anchors | Anchors | Required. Array of finite number; maximum items 256. |
| mapped | Mapped | Required. Array of finite number; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| mappedScore | Mapped Score | Required. Finite number. |
| interval | Interval | Required. Safe integer. |

}Limitations and assumptions
- Mapped values need not be increasing and no extrapolation is allowed. The supplied anchor map does not establish a validated goal-attainment scale or interval-level clinical measurement.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use the intended assessment or motion-analysis protocol with verified timing, units, and event annotations. A complete interpretation needs the relevant measurement properties and task context beyond this local calculation.
