Abstract

OBJECTIVE: To determine the relationship between assisted TUG performance and the PDQ-39, and to determine if adjusting the TUG score (adding time) improves the relationship between TUG performance and the PDQ-39 in person with PD that use assistive devices and/or push off.

DESIGN: Cross-sectional SETTING: 20 participating National Parkinson Foundation Centers of Excellence in the United States, Canada, the Netherlands, and Israel. PARTICIPANTS: Data were obtained from 6,624 participants without exclusion at 20 participating sites. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The relationship between the 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 was slightly lower (R2 = 0.384) compared to the correlation between non-assisted TUG scores and PDQ-39 mobility scores (R2 = 0.409). Adjusting assisted TUG performance scores for push off and for use of an assistive device resulted in a modest increase in correlation (R(2) = 0.399).

CONCLUSION: 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.
