How accurate is the 6 minute walk test?
The correlation of the 6MWT to peak VO2 is moderate to good, with 6MWT being between 83% and 91% accurate in predicting peak VO2 if distance walked is less than 450 to 490 meters, respectively.
How reliable is the 6-minute walk test?
The 6MWD showed excellent test-retest reliability (ICC2,1: 0.91). The mean change in 6MWD after the second 6MWT was 18m (95%CI 11–24m), with 73% of the patients walking further in the second test. The SEM and MDC95% for the 6MWT were 35 m and 98 m, respectively.
What is a good distance for a 6-minute walk test?
Moreover, the 6MWT better reflects activities of daily living than other walk tests. Recently, the American Thoracic Society developed guidelines for the 6MWT in clinical settings. In healthy subjects, the 6-min walk distance (6MWD) ranges from 400 to 700 m, the main predictor variables being gender, age and height.
What is a disadvantage of the 6-minute walk test?
The 6MWT is not without limitations. The test does not provide insight into the mechanisms of exercise limitation. Its results can be affected by a variety of factors unrelated to cardiopulmonary status, including age, sex, height, and weight.
Is the 6-minute walk test in a cardiac rehabilitation population valid and reliable?
Conclusions: The 6-minute walk is a valid and reliable method of assessing functional ability in a Phase II/III CR population. A learning effect of 6% was observed over the three walks; however, it is unknown if this learning effect will be retained over time.
What does it mean if you fail the 6 minute walk test?
What the scores mean. The higher a person's score, the better their exercise tolerance. A low score correlates with lower function. The results of the 6MWT can help doctors evaluate the effectiveness of therapeutic intervention to increase exercise tolerance.
Is the 6 minute walk test done without oxygen?
The test can be performed with or without the use of supplemental oxygen. You may be asked to use supplemental oxygen during the test, if you normally use it when walking. Before the test begins, your healthcare provider will measure your heart rate, blood pressure, and oxygen saturation level.

What is the difference between the 6 minute walk test and the 12 minute walk test?
The 6MWT is a supervised test that measures the distance a patient can walk on a hard, flat surface over a six-minute period, whereas the 12MWT prolongs the evaluation to 12 minutes. The American Thoracic Society (ATS) provides guidelines for the standardization of this test in order to maximize reliability.
