Description
Subtract supplied bench preload and compare to a reference; no fitting or therapeutic force recommendation.
Orthopedic bench and imaging records combine force, displacement, geometric dimensions, coordinate frames, weights, and reference measurements. An ideal material term or dimensional margin depends on its model and units. It does not by itself establish implant compatibility, tissue behavior, or safe clinical loading.
Subtract supplied bench preload and compare to a reference; no fitting or therapeutic force recommendation.
When to use this tool
Use Orthosis Preload Reference Force when you need this bench, geometry, reference, score-denominator, or measurement term from supplied data.
How to use the tool and how it works
- Enter measuredForce, preloadForce, referenceForce. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read incrementalForce, referenceGap. Use the output convention below.
Return incrementalForce=measuredForce-preloadForce and referenceGap=incrementalForce-referenceForce.1

| referenceForce | Reference Force | Required. Finite number. |
| Output field | Interpretation | Returned shape |

| incrementalForce | Incremental Force | Required. Finite number. |
| referenceGap | Reference Gap | Required. Finite number. |

}Limitations and assumptions
- All inputs need one force unit and sign convention. Negative increments are allowed; preload, calibration, orthosis behavior, safe loading, and clinical suitability are not verified.
- 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 a complete material, imaging, or assessment model for the intended question. Verify measurement units, calibration, load conditions, geometry, missingness, and reference assumptions before combining terms.
