The association between poor performance on SPPB and all-cause mortality remained highly consistent independent of follow-up length , subsets of participants , geographic area , and age of the population .
Conclusions An SPPB score lower than 10 is predictive of all-cause mortality .
The systematic implementation of the SPPB in clinical practice setting s may provide useful prognostic information about the risk of all-cause mortality .
Background The Short Physical Performance Battery ( SPPB ) is a well-established tool to assess lower extremity physical performance status .
Its predictive ability for all-cause mortality has been sparsely reported , but with conflicting results in different subsets of participants .
The aim of this study was to perform a meta- analysis investigating the relationship between SPPB score and all-cause mortality  .
Mobility stress test approach to predicting frailty, disability, and mortality in high-functioning older adults.
OBJECTIVES To examine the validity of the Walking While Talking Test ( WWT ) , a mobility stress test , to predict frailty , disability , and death in high-functioning older adults . DESIGN Prospect i ve cohort study . SETTING Community sample . PARTICIPANTS Six hundred thirty-one community-residing adults aged 70 and older participating in the Einstein Aging Study ( mean follow-up 32 months ) . High-functioning status at baseline was defined as absence of disability and dementia and normal walking speeds . MEASUREMENTS Hazard ratios ( HRs ) for frailty , disability , and all-cause mortality . Frailty was defined as presence of three out of the following five attributes : weight loss , weakness , exhaustion , low physical activity , and slow gait . The predictive validity of the WWT was also compared with that of the Short Physical Performance Battery ( SPPB ) for study outcomes . RESULTS Two hundred eighteen participants developed frailty  , 88 developed disability , and 49 died . Each 10-cm/s decrease in WWT speed was associated with greater risk of frailty ( HR = 1.12 , 95 % confidence interval ( CI ) = 1.06 - 1.18 ) , disability ( HR = 1.13 , 95 % CI = 1.03 - 1.23 ) , and mortality ( HR = 1.13 , 95 % CI = 1.01 - 1.27 ) . Most associations remained robust even after accounting for potential confounders and gait speed . Comparisons of HRs and model fit suggest that the WWT may better predict frailty whereas SPPB may better predict disability . CONCLUSION Mobility stress tests such as the WWT are robust predictors of risk of frailty , disability , and mortality in high-functioning older adults
