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 .
Ten years down the road: predictors of driving cessation.
PURPOSE Recent prospect i ve studies have found that cognition is a more salient predictor of driving cessation than physical performance or demographic factors among community-dwelling older adults . However , these studies have been limited to 5 years of follow-up . The current study used data from the Maryl and Older Drivers Project to examine predictors of  driving cessation in older adults over a 10-year period . DESIGN AND METHODS Participants ( N = 1,248 ) completed baseline and 5-year assessment s of physical and cognitive abilities .  Driving status was ascertained at baseline and annually thereafter . RESULTS Cox proportional hazard models were used to examine the risk of driving cessation as a function of demographic , physical , and cognitive predictors . The final model indicated three significant predictors of driving cessation , older age at baseline ( hazard ratio [ HR ] = 1.12 , p < .001 ) , days driven per week ( HR = 0.83 , p = .05 ) , and slower speed of processing as measured by the Useful Field of View Test ( HR = 1.76 , p < .01 ) . IMPLICATION S These results underscore the importance of cognitive speed of processing to the maintenance of driving . Brief cognitive assessment can be conducted in the field to potentially identify older adults at increased risk for driving cessation . Further research is needed to determine the costs and potential benefits of such screening
