ObjectivesTo determine whether a performance battery and its components aid in predicting injurious falls. DesignLongitudinal analysis; prospective cohort study. SettingClinical site. ParticipantsBoston-area community-dwelling adults (N=755; mean ageSD 78.15.4, 64.1% female, 77.6% white). MeasurementsBaseline functional performance was determined according to the Short Physical Performance Battery (SPPB), measuring balance, gait speed, and five repeated chair stands. Fall history (past year) and efficacy in performing 10 daily activities without falling were assessed. Falls were assessed using a daily calendar over 4years. Injurious falls were defined as resulting in fractures, sprains, dislocations, pulled or torn muscles, ligaments, or tendons or seeking medical attention. ResultsPoorest chair stand performance (16.7seconds) was associated with greater hazard of injurious falls than in all other chair stand performance groups (hazard ratio (HR)=1.96, 95% confidence interval (CI)=1.18-3.26 for 16.7vs. 13.7-16.6seconds; HR=1.65, 95% CI=1.07-2.55 for 16.7vs. 11.2-13.6seconds, HR= 1.60, 95% CI=1.03-2.48 for 16.7vs. <11.2seconds). SPPB did not predict injurious falls. Fall history predicted injurious falls (HR=1.82, 95% CI=1.39-2.39); falls efficacy did not. Fall history and a slow chair stand (<16.7seconds) had a 2-year cumulative incidence rate of an injurious fall of 46% (95% CI=0.34-0.58), nearly the combined rate of a positive fall history (0.29, 95% CI=0.25-0.34) and a slow chair stand alone (0.21, 95% CI=0.13-0.30). ConclusionAn easily administered chair stand test may be sufficient for evaluating performance as part of a risk stratification strategy for injurious falls.
