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 (more than or equal to80 years) to 528.1 meters (30–39 years) for women and 355.7 meters (more than or equal to 80 years) to 540.4 meters (30–39 years) for men. Rating of perceived exertion and age significantly predicted walking distance (P less than .0001). Conclusions: These findings provide reference values for a clinically feasible 12-meter 6MWT pathway for adults over 20 years of age.
