Description
Compare explicit device and limb sides while preserving unknown-side status.
Orthopedic measurements distinguish side, reference origin, image scale, device lots and mechanical test geometry. A two-point load/displacement slope is structural stiffness rather than a material modulus. Supplied matches, offsets and calibration factors need verified anatomy, devices and test conditions before clinical or design interpretation.
Compare explicit device and limb sides while preserving unknown-side status.
When to use this tool
Use Orthosis Device Side Match when you already have recordedLimbSide, deviceSide and need to compare explicit device and limb sides while preserving unknown-side status.
How to use the tool and how it works
- Enter recordedLimbSide, deviceSide. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read comparable, matches. Inspect comparable, matches before interpreting the associated values.
Require each side left, right or unspecified. comparable means neither is unspecified; matches additionally requires equality.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedLimbSide | Recorded Limb Side | Required. Text; one of "left", "right", "unspecified"; maximum UTF-16 length 8192. |
| deviceSide | Device Side | Required. Text; one of "left", "right", "unspecified"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| comparable | Comparable | Required. Boolean. |
| matches | False when either side is unspecified, including two unspecified sides. | Required. Boolean. |
{
"input": {
"recordedLimbSide": "left",
"deviceSide": "left"
},
"output": {
"comparable": true,
"matches": true
}
}Limitations and assumptions
- Two unspecified sides give matches=false, not a confirmed match; the tool does not establish device fit, identity or safe placement.
- 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.
Alternative or Complementary methods
Inspect actual device specifications, calibrated images and the full measurement or test setup. Use complete geometry and material/test information when relating a local scale, side match or structural secant slope to a physical or clinical question.
