Each metric in a completed assessment is assigned a grade based on its value relative to documented thresholds.
Grade levels
- Green — the value is within the expected range.
- Yellow — the value is borderline. May warrant monitoring or attention.
- Red — the value is outside the expected range.
Grades are produced per metric, then aggregated to an overall grade for the module using a worst-case rule: if any metric is red, the overall is red; if any is yellow, the overall is yellow; otherwise green.
What grades mean
A grade is a descriptive observation of how the value compares to a reference threshold. It is not:
- A diagnosis
- A statement of clinical significance
- A prediction of injury risk
- A validated clinical cutoff
See our Disclaimer for the full intended use statement.
What grades do not mean
- Red ≠ injured. A red grade means the value is outside the reference band. Many factors cause this, including measurement error, lighting, pacing, or genuine movement quality.
- Green ≠ healthy. A green grade means the single metric is within the reference band. It does not clear the subject for any activity.
- Grades across metrics are not comparable. A red gait speed and a red knee valgus reflect very different things.
How to use grades
- Treat grades as prompts for closer review, not conclusions.
- Cross-check grades against what you observed during the capture.
- Compare the subject to themselves across sessions rather than to the threshold alone.
- Consider grade changes over time more meaningful than absolute grades at one point in time.
Threshold provenance
Every threshold used in grading has a documented source type. See How thresholds were chosen for details.
