Estimate functional walking performance with adult reference options. Compare distance, symptoms, oxygen change, and pace. Clear outputs support reviews, follow up, counseling, and documentation.
Male: Predicted 6MWD = (7.57 × height cm) − (5.02 × age) − (1.76 × weight kg) − 309
Female: Predicted 6MWD = (2.11 × height cm) − (2.29 × weight kg) − (5.78 × age) + 667
Lower limit of normal: Male LLN = predicted − 153. Female LLN = predicted − 139.
Male: Predicted 6MWD = 164.08 + 78.06 − (1.90 × age) + (1.95 × height cm)
Female: Predicted 6MWD = 164.08 − (1.90 × age) + (1.95 × height cm)
Derived metrics: % predicted = actual distance ÷ predicted distance × 100. Average speed = distance ÷ total seconds.
A lower percent predicted or a result below LLN can support functional review, but this tool does not diagnose a cause.
| Case | Reference | Sex | Age | Height | Weight | Distance | Predicted | % Predicted | Example note |
|---|---|---|---|---|---|---|---|---|---|
| A | Adult | Male | 58 | 175 cm | 78 kg | 420 m | 587.31 m | 71.52% | Below predicted adult reference. |
| B | Adult | Female | 64 | 162 cm | 68 kg | 360 m | 483.18 m | 74.51% | Reduced relative to predicted value. |
| C | Pakistani | Male | 38 | 172 cm | 74 kg | 510 m | 505.34 m | 100.92% | Near expected distance for selected model. |
It estimates walking distance performance, percent predicted, pace, and selected change measures from a six-minute walk entry. It also compares the observed result with a reference equation and, when available, the lower limit of normal.
Choose the reference that best matches your patient population and testing context. Adult reference equations and local population equations can give different percent predicted values, so the chosen model should stay consistent across serial comparisons.
Each equation was derived from a different population and uses different predictors. A result can look stronger or weaker depending on the model. That is why repeated follow-up should usually keep the same equation.
You can enter a shorter duration, and the calculator will still show pace. However, comparison with standard six-minute references becomes less direct, so interpret the result very cautiously.
No. Entered saturation changes can highlight a possible concern, but they do not explain the cause. Sensor quality, effort, oxygen setup, and clinical condition all matter when reviewing desaturation.
Some users document the final measured distance directly, while others record corridor laps and a final partial segment. Exact distance takes priority because it usually reflects the official measured result.
Sometimes not. People often do better after becoming familiar with the test. Standardized repeat testing can reduce that learning effect and make follow-up comparisons more useful.
No. This tool organizes values and reference comparisons, but real interpretation also depends on symptoms, diagnosis, medications, oxygen use, safety factors, and test conditions.
