Linear Model–Based Meansa

  • a The model likelihood ratio chi square <.001 for all models. Models include the following design variables and covariate adjustments: sex (categorical, 2 levels), time (categorical, 4 levels), group × time interactions (6 dummy variables), levodopa equivalents (continuous). The control group participated in a home-based program of exercises recommended by the National Parkinson Foundation,18 the AE group participated in a standard aerobic endurance program, and the FBF group participated in a flexibility/balance/function program specifically designed for people with Parkinson disease (PD). UPDRS=United Parkinson's Disease Rating Scale, ADL=activities of daily living, CS-PFP=Continuous Scale—Physical Functional Performance Test, FRT=Functional Reach Test, V̇o2=oxygen uptake, PDQ-39=39-item Parkinson's Disease Questionnaire, SE=standard error.
