Performance on 6-minute walk test on a 15-m-long course. (a) As represented by SD from normal controls (refs. 19–23), only one individual performed within the normal range. (b) Average 6MWT distance (m) versus average predicted 6MWT distance (m) for subjects 4–19 years of age and for subjects 20–32 years of age. Average predicated values for subjects were calculated utilizing regression equations that take into account height and age.
