6 Minute Walk Test Calculator - 6MWT

The 6 Minute Walk Test Calculator is a simple and effective tool used to assess a person's functional capacity and endurance by measuring the distance they can walk in six minutes.

 

It is commonly used in medical evaluations and research studies to evaluate cardiovascular and pulmonary health.

 

What is a 6 Minute Walk Test (6MWT)?

The 6MWT is a simple and commonly used exercise test to assess the functional capacity and exercise tolerance of an individual.

• It involves walking at a comfortable pace for six minutes in a straight path or along a designated course.
• The distance covered in six minutes is recorded as the primary outcome, reflecting the person's aerobic and cardiovascular endurance.
• The test is frequently employed in clinical settings to evaluate the functional status of patients with various medical conditions, such as heart and lung diseases.
• It provides valuable information about a person's exercise capacity, response to treatment, and overall physical fitness.

 

Advantages of the 6-minute walk test:

• Simplicity
• Low cost
• Easy to standardize
• Low patient burden (feasible even for elderly and frail patients)

 

Steps to Calculate 6-Minute Walk Test

Here are the Steps to Calculate 6-Minute Walk Test.

• Enter Gender & Age
• Enter Height & Weight
• Enter Distance Walked (meters)
• Calculate Expect Distance

 

 

6-Minute Walk Test Formula predicted distance equations

The 6 minute walk test (6MWT) predicted distance equations.

For MEN:

6MWD = (7.57 * height in cm) – (5.02 * age in years) – (1.76 * weight in kg) – 309

 

For WOMEN:

• 6MWD = (2.11 * height in cm) – (2.29 * weight in kg) – (5.78 * age in years) + 667

 

6MWD represents the predicted 6-minute walk distance in meters.

• Height should be entered in centimeters (cm).
• Weight should be entered in kilograms (kg).
• Age should be entered in years.

The calculator provided by our 6-minute walk test tool includes a built-in converter to handle different units for ease of use.

 

6 minute walk test - norms

The equations provided by the authors predict the distance that a patient should walk in the 6 minute walk test (6MWT) based on their height, weight, age, and gender.

 

Additionally, they have determined the lower limits of the norm for both men and women, which can be calculated using the following formulas:

For MEN: Lower Limit = 6MWD - 153

For WOMEN: Lower Limit = 6MWD - 139

 

In both cases, 6MWD represents the 6 minute walk distance expressed in meters. These lower limits can be used as reference values to assess a patient's performance in the 6MWT and compare it with the expected norm for their gender.

 

It can be particularly useful to identify individuals who may have reduced functional capacity or potential health concerns based on their 6MWT results.

 

Factors the decrease and increase the 6MWT result:

Here are Factors the decrease and increase the 6MWT result:

Decreasing	Increasing
shorter height	taller height
female sex	male sex
older age	increased motivation
higher body weight	higher muscle mass
cardiovascular or pulmonary disease	past performance of the test

 

6 Minute Walk Test Example

In this practical example, the 6 minute walk test (6MWT) calculator was used to evaluate an exemplary patient's performance. Let's summarize the results:

1. We need to start by calculating 6 minute walk test predicted distance:

• 6MWD = (7.57 * height) – (5.02 * age) – (1.76 * weight) – 309
• 6MWD = (7.57 * 177 cm) – (5.02 * 72 yo) – (1.76 * 80 kg) – 309
• 6MWD = 1340 – 361 – 141 – 309
• 6MWD = 529 meters

2. Now we can check if this result falls into 6 minute walk test norm:

• lower limit = 6MWD - 153
• lower limit = 529 - 153
• lower limit = 376 meters

The patient result of 432 meters is above the lower limit.

 

3. Finally, we can calculate percentage our patient managed compared to the expected distance of a healthy patient**:

• % expected = 423 / 529 * 100%
• % expected = 0.82 * 100%
• % expected = 82%

 

Overall, the patient's 6MWT result is encouraging, as it surpasses the lower limit of the norm and reflects a reasonably good functional capacity compared to the expected distance for his age, height, and weight. However, the 6MWT is just one part of a comprehensive evaluation of an individual's physical fitness and health, and other factors should also be considered in the clinical context.
