Conclusions The Timed Up- and -Go test measure appears not to be a useful measure of physical functioning for the driving outcomes included here .
The Rapid Pace Walk may be useful in studies of driving ability and exposure .
Background Improving physical functioning may be a future intervention to keep older adults driving safely longer as it can help maintain both physical and cognitive health longer .
This systematic review assesses the evidence on the association between three physical functioning measures : the Short Physical Performance Battery , the Timed Up- and -Go test , and the Rapid Pace Walk with driving outcomes in older adults .
Physical Performance Measures as Predictors of Mortality in a Cohort of Community-dwelling Older French Women
This prospect i ve cohort study evaluate the predictive value of physical performance measures for mortality in older French women , in particular those with a high health status . The subjects were 7,250 community-dwelling non-disabled French women aged 75 years or older , enrolled in the Epidémiologie de l’ostéoporose ( EPIDOS ) study .  The short physical performance battery ( SPPB ) , including walking speed , repeated chair st and s , and balance tests , was administered and h and grip strength was measured . Anthropometric measurements , physical function , cognitive performance , sensory status , smoking , medical history , medication use , subjective self- assessment of health status , and physical activity level were assessed at the baseline visit . During a mean follow-up of 3.8 years , 754 ( 10.4 % ) participants died . Complementary analysis was performed on the 2,157 non-disabled healthiest participants ( no disease at baseline ) . The SPPB and h and grip strength distinguished a gradient of risk for mortality from a low to high functional spectrum . Risk of death was 2.04-fold higher in poor ( SPPB 0–6 ) than in good ( SPPB 10–12 ) performers and 1.56-fold higher in participants with lower tertile grip strength . Walking speed alone also distinguished a gradient of mortality risk . After adjustment for confounders , low SPPB , grip strength score and slow walking speed remained significantly associated with death . In the non-disabled healthiest women , no physical performance measure predicted death . In community-dwelling elderly French women , physical performance measures significantly and independently predicted mortality . Increased risk of death was partly explained by baseline health status and was absent in the healthiest elderly
