Objective: To examine the relationship between Timed Up and Go (TUG) performance, verbal executive function (EF) performance, and quality-of-life (QOL) measures in Parkinson's disease (PD).
Design: Cross-sectional.
Setting: Sixteen movement disorder centers from across the United States.
Participants: Patients with PD (N=1964).
Interventions: Not applicable.
Main Outcome Measures: TUG test, immediate and delayed 5-word recall, verbal fluency, PD QOL Questionnaire.
Results: TUG performance and verbal EF performance were significantly associated with, and predictors of, QOL measures, having the greatest association and predictability with the mobility domain of the QOL measures.
Conclusions: The TUG test and verbal EF tests have QOL correlates, making the combined evaluation of mobility, cognitive, and QOL decline a potential examination tool to evaluate the sequelae of PD.
