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 .
Examination of cognitive and instrumental functional performance as indicators for driving cessation risk across 3 years.
PURPOSE The purpose of this study was to prospect ively examine the role of cognitive and instrumental functional performance in driving cessation while simultaneously accounting for any contributions of demographics , vision , physical performance , and health among a sample of older adults without dementia . DESIGN AND METHODS Included in the analyses were 1,838 participants from the Advanced Cognitive Training for Independent and Vital Elderly ( ACTIVE ) study who were drivers at baseline and completed the third-year assessment . Participants completed baseline assessment s of sociodemographic characteristics , health , sensory function , physical function , cognitive abilities , instrumental functional performance , and depressive symptoms . Driving status was again ascertained 3 years later . RESULTS We used Cox proportional hazard analyses to examine prospect i ve predictors of driving cessation over a 3-year period . The final model indicated four significant risk factors for driving cessation : older age ( hazard ratio [ HR ] = 1.06 , p = .009 ) , poorer balance as measured by the Turn 360 degrees test ( HR = 1.17 , p = .002 ) , slower cognitive speed of processing as measured by the Useful Field of View test ( HR = 1.37 , p = .004 ) , and poorer instrumental functional performance as assessed by the Everyday Problems Test ( HR = 1.59 , p < .001 ) . IMPLICATION S Although vision , health , and physical abilities are commonly considered when determining driving capacity , cognitive speed of processing and instrumental functional performance may be better indicators of subsequent likelihood of driving cessation across 3 years among older adults . Poor health and vision may only impact driving cessation to the extent that cognitive speed of processing and instrumental functioning are affected
