OBJECTIVES: To determine whether @entity1 with poorer lower extremity functioning have reduced physical activity levels. DESIGN: Cross-sectional. SETTING: Three Chicago-area medical centers. @entity1 : Two hundred twenty-five @entity1 with @entity3657 ( @entity3657 ) and 121 individuals without @entity3657 . MEASUREMENTS: The summary performance score (SPS) was determined for all @entity1 . The SPS combines data on walking velocity, time for five repeated chair rises, and standing balance. Each test is scored on a 0 to 4 scale (4 = best). Scores are summed to create the SPS (0-12 scale, 12 = best). All @entity1 wore a vertical accelerometer for 7 days to measure physical activity. RESULTS: The SPS was associated linearly with 7-day physical activity levels of @entity1 with (P< .0001) and without @entity3657 (P< .0001). This relationship was maintained even after restricting analyses to subsets of @entity1 who reported that they could walk a quarter of a mile and up and down stairs without difficulty (P< .001) and were able to walk for 6-minutes without stopping (P< .001). In multiple linear regression analyses, the SPS was associated with physical activity in @entity1 with (P< .01) and without @entity3657 (P< .001), adjusting for age, sex, race, comorbidities, ankle brachial index, @entity16 , and leg symptoms. CONCLUSION: In @entity1 with and without @entity3657 who have impaired lower extremity performance, reduced physical activity levels may contribute to subsequent disability. Future study is needed to determine whether interventions to increase physical activity can prevent functional decline in @entity1 with a low SPS.

Lower extremity performance is associated with daily life physical activity in individuals with and without XXXX .
