Description
Signed bench preload correction and supplied reference comparison.
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.
Signed bench preload correction and supplied reference comparison.
When to use this tool
Use Physio Bench Preload Force Gap 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 force, preload, expectedIncrement. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read netForce, residual. Use the output convention below.
Return netForce=force-preload and residual=netForce-expectedIncrement.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| force | Force in the chosen signed direction and unit. | Required. Finite number. |
| preload | Preload | Required. Finite number. |
| expectedIncrement | Expected Increment | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| netForce | Net Force | Required. Finite number. |
| residual | Signed observed-minus-implied discrepancy under the stated formula. | Required. Finite number. |

}Limitations and assumptions
- All inputs need one force unit and sign convention. The supplied preload and expected increment are not verified; this bench calculation does not assess strength or treatment response.
- 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.
