Percent Fatigue
Fatigue is determined as the difference in the distance walked during the first and last test minute expressed as a percent change, where a positive value represents fatigue.

Percent Predicted 6MWT Distance
The percent of the predicted distance on the 6MWT can be computed from normative values. The predicted distance for their gender, age, height, and weight, can provide a comparison to the healthy population and represent a varied range of walking impairment and/or diminished walking ability. This calculator uses predicted equations from the 1000 Norms Project.
