Sprint Shin Angle Screen
Compare the measured value with caller-supplied bounds for sprint shin angle screen.
Description
Sprint shin-angle screening compares a measured angle with a caller-selected interval.
Sprint shin-angle screening compares a measured angle with a caller-selected interval. Signed margins identify deviations beyond either edge.1
Compare the measured value with caller-supplied bounds for sprint shin angle screen.
When to use Sprint Shin Angle Screen
Use this tool to compare the measured value with caller-supplied bounds for sprint shin angle screen.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Sprint Shin Angle 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 shinAngleDegrees, minimumAngleDegrees, maximumAngleDegrees using the field table and calculation rules, then run the tool.
- Read marginToMaximum, marginToMinimum, withinRange. 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 |
|---|---|---|---|
| shinAngleDegrees | Shin angle (°) | number | Required |
| minimumAngleDegrees | Minimum angle (°) | number | Required |
| maximumAngleDegrees | Maximum angle (°) | number | Required |
Enter finite angles with minimum≤maximum. Return both margins and inclusive within-range flag. Equal bounds admit only their exact angle.
minMargin=value−minimum; maxMargin=maximum−value Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| marginToMaximum | Margin to maximum (°) | number |
| marginToMinimum | Margin to minimum (°) | number |
| withinRange | Within range | boolean |

}Limitations and assumptions
No anatomical angle convention, sprint technique model or coaching target is embedded.
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.
Alternative or Complementary methods
Use Triple Extension Sequence Check: Check hip, knee, and ankle peak timing against caller-defined sequencing criteria. For a complementary task, use Dynamic Valgus Angle Screen: Compare the measured value with caller-supplied bounds for dynamic valgus angle screen.
