OBJECTIVES: To determine (1) the relationship between assisted timed Up and Go
(TUG) performance and the Parkinson's Disease Questionnaire-39 (PDQ-39), and (2)
whether adjusting the TUG score (adding time) improves the relationship between
TUG performance and the PDQ-39 in persons with Parkinson disease (PD) who use
assistive devices or push off, or both. DESIGN: Cross-sectional. SETTING: Twenty
participating National Parkinson Foundation Centers of Excellence. PARTICIPANTS:
Data were obtained from participants (N=6624) without exclusion at the 20
participating sites. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The relationship between TUG scores and PDQ-39 mobility scores was determined using
the method of linear least squares. Adjusted scores were determined through
minimizing the sum of the squared error. RESULTS: The correlation between
assisted TUG scores and PDQ-39 mobility scores was slightly lower (R(2)=.384)
compared with the correlation between nonassisted TUG scores and PDQ-39 mobility
scores (R(2)=.409). Adjusting assisted TUG performance scores for push off and
for use of an assistive device resulted in a modest increase in correlation
(R(2)=.399). CONCLUSIONS: Applying adjustments to assisted TUG may provide
clinically important information for evaluating balance, mobility, and falls, and
for determining the most effective therapeutic strategies for persons with PD.
