Short Physical Performance Battery, usual gait speed, grip strength and Vulnerable Elders Survey each predict functional decline among older women with breast cancer

SPPB, gait speed, grip strength and VES-13 all demonstrated excellent predictive abilities for functional decline. Larger studies are warranted to confirm the utility of these measures for identifying older adults with cancer at increased risk for functional decline, who may then be targeted for studies to explore the effects of interventions to improve function.
