Normal values, as well as determining factors, for the 6-minute walk test are
available for nondisabled adults, but less is known about individuals with
Parkinson disease (PD). This study created a PD-specific reference equation and
identified unique factors associated with 6-minute walk distance (6MWD). Eighty
individuals (mean +/- standard deviation [SD] age: 66.3 +/- 9.8 yr) with mild to
moderate PD underwent a neurological examination and completed a small battery of
tests to assess their balance confidence, fall risk, mobility, and balance. Their
mean +/- SD 6MWD was 394.1 +/- 98.4 m (95% confidence interval: 370.0-418.1).
Stepwise multiple regression analysis demonstrated that timed up-and-go (TUG)
test, one-leg stance (OLS) test, and sex were significant independent
contributors to 6MWD and accounted for 56.6% of the variance. The resulting
PD-specific regression equation is 6MWD pred = 543.06 + (-10.83 degrees TUG) +
(2.04 degrees OLS) + (-44.44 degrees sex). (For sex, 0 = female, 1 = male.)
Future interpretation of 6MWD in individuals with PD may be enhanced if expressed
as a percentage of the value predicted utilizing this reference equation.
