Inputs
0 of 4SexUsed by the equation
years
Actual (total) body weight
Optional
Patient values are shared with every calculator.
When to use
- Interpreting a 6-minute walk test in adults (derived in healthy adults aged 40 to 80).
Pearls and pitfalls
- Follow standardized test instructions (30 m corridor, standardized encouragement).
- Outside ages 40 to 80 the equations extrapolate.
Why use
Predicted distance, lower limit of normal and percent predicted in one place.
Men: 7.57 × height(cm) − 5.02 × age − 1.76 × weight(kg) − 309 m (LLN: −153 m). Women: 2.11 × height(cm) − 2.29 × weight(kg) − 5.78 × age + 667 m (LLN: −139 m)
