Fingertip Floor Distance Screen
Screen fingertip-to-floor distance with a caller-provided flexibility limit.
Description
Fingertip-to-floor screening compares a signed reach gap with a maximum.
Fingertip-to-floor screening compares a signed reach gap with a maximum. Negative gaps can describe reaching below the floor reference.1
Screen fingertip-to-floor distance with a caller-provided flexibility limit.
When to use Fingertip Floor Distance Screen
Use this tool to screen fingertip-to-floor distance with a caller-provided flexibility limit.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Fingertip Floor Distance Screen and understand its results
- Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
- Enter fingertipFloorGapCm, maximumGapCm using the field table and calculation rules, then run the tool.
- Read marginCm, withinTarget. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| fingertipFloorGapCm | Fingertip floor gap cm | number | Required |
| maximumGapCm | Maximum gap cm | number | Required |
Enter finite signed gap and nonnegative maximum cm. Return margin and inclusive flag.
margin=maximum−gap; passes=gap≤maximum Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| marginCm | Margin cm | number |
| withinTarget | Within target | boolean |

}Limitations and assumptions
No landmark technique, joint-specific flexibility or clinical diagnosis is supplied.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
