Six-Minute Walk Test (6MWT) Reference Distances by Age and Sex Using a 12-Meter Pathway

Purpose:The Six-Minute Walk Test (6MWT) is a standardized measure of walking distance, widely used in rehabilitation across a variety of health conditions. Clinical space constraints frequently result in shortening the pathway, reducing the overall distance walked. A 12-meter pathway is a reliable, clinically feasible option; however, published reference values for comparison to predicted distance walked do not exist for a shortened pathway. The objective of this study was to establish reference values for a 12-meter 6MWT pathway in adults 20 years of age and older. Methods:Observational, cross-sectional study using a convenience sample of adults without mobility limitations. The 6MWT was performed using the 12-meter pathway. Descriptive statistics were calculated by sex and decade of life. A regression analysis was performed to determine the relationship between distance walked and age, rate of perceived exertion, and sex.Results:Overall, 238 participants performed the 6MWT. Mean distance walked ranged from 362.7 meters (≥80 years) to 528.1 meters (30-39 years) for women and 355.7 meters (≥80 years) to 540.4 meters (30-39 years) for men. Rating of perceived exertion and age significantly predicted walking distance (P <.0001).Conclusions:These findings provide reference values for a clinically feasible 12-meter 6MWT pathway for adults over 20 years of age.
