Equations of Selman et al for Estimating the 2-Minute Walking Distance (2MWD) of a Healthy Adult

Patient selection: healthy adult from 18 to 89 years of age

Parameters:

(1) age in years

(2) gender (female 0, male 1)

distance in meters from multiple linear regression analysis =

= (26.955 * (points for gender)) - (0.954 * (age)) + 243.262

reference equation for the distance in meters =

= (19.987 * (points for gender)) - (1.165 * (age)) + 252.583

lower limit of the normal range =

= (distance from the reference equation) - 44
