OBJECTIVE: To identify the neuromuscular attributes that are associated with
self-reported mobility status among older primary care patients. DESIGN: Cohort
study. SETTING: Metropolitan-based health care system. PARTICIPANTS:
Community-dwelling primary care patients aged >/=65 years (N=430), with
self-reported modification of mobility tasks resulting from underlying health
conditions. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Basic and
Advanced Lower Extremity Function as measured by the Late Life Function and
Disability Instrument. RESULTS: We constructed multivariable linear regression
models evaluating both outcomes. For Basic Lower Extremity Function, leg
strength, leg velocity, trunk extensor muscle endurance, and ankle range of
motion (ROM) were statistically significant predictors (P<.001, R(2)=.21). For
Advanced Lower Extremity Function, leg strength, leg strength asymmetry, leg
velocity, trunk extensor muscle endurance, and knee flexion ROM were
statistically significant predictors (P<.001, R(2)=.39). Sensitivity analyses
conducted using multiple imputations to account for missing data confirmed these
findings. CONCLUSIONS: This analysis highlights the relevance and importance of 5
categories of neuromuscular attributes: strength, speed of movement, ROM,
asymmetry, and trunk stability. It identifies novel attributes (leg velocity and
trunk extensor muscle endurance) relevant to mobility and highlights that
impairment profiles vary by the level of mobility assessed. These findings will
inform the design of more thorough and potentially more effective disability
prevention strategies.
