1. What is the Six Minute Walk Test?

The Six Minute Walk Test (6MWT) is a submaximal exercise test that assesses functional capacity by measuring the distance a patient can walk quickly on a flat, hard surface in six minutes. It is commonly used to evaluate cardiopulmonary function and exercise tolerance.

2. How Does the Calculator Work?

The calculator uses age and sex adjusted formulas to predict the expected distance:

Where:

• \( Age \) — Age in years
• \( Sex \) — Male or Female
• Different coefficients apply based on gender and age ranges

Explanation: The equation accounts for normal age-related decline in exercise capacity and physiological differences between genders.

3. Importance of Predicted Distance Calculation

Details: Calculating predicted distance helps establish baseline expectations, monitor disease progression, assess treatment effectiveness, and evaluate functional status in various clinical conditions.

4. Using the Calculator

Tips: Enter age in years and select gender. The calculator will provide the predicted distance based on established reference equations.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal Six Minute Walk Distance?
A: Normal values vary by age, sex, and height. Generally, healthy adults walk 400-700 meters, with predicted values decreasing with age.

Q2: How is the test performed?
A: Patients walk back and forth along a measured corridor for 6 minutes while standardized encouragement is provided.

Q3: What conditions affect Six Minute Walk Distance?
A: Cardiopulmonary diseases, musculoskeletal disorders, neurological conditions, and general deconditioning can significantly reduce walking distance.

Q4: What is considered a clinically significant change?
A: A change of 30-50 meters is generally considered clinically meaningful in most patient populations.

Q5: Are there contraindications for the test?
A: Yes, including unstable angina, recent myocardial infarction, resting tachycardia, and uncontrolled hypertension.
