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 .
Can high-risk older drivers be identified through performance-based measures in a Department of Motor Vehicles setting?
OBJECTIVES To evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision ( MVC ) involvement in a cohort of older drivers . DESIGN Prospect i ve cohort study . SETTING Motor Vehicle Administration ( MVA ) field sites in Maryl and . PARTICIPANTS Of the 4,173 older drivers invited to participate in the study , 2,114 individuals aged 55 to 96 agreed to do so . These analyses focus on 1,910 individuals recruited through MVA field sites . MEASUREMENTS  Gross Impairment Screening Battery  , which included  Rapid Pace Walk , Head/Neck Rotation , Foot Tap , Arm Reach , Cued Recall , Symbol Scan , Visual Closure subtest of the Motor Free Visual Perception Test ( MVPT ) , Delayed Recall , and Trail Making Test with an Abbreviated Part A and  st  and ard Part B ; Useful Field of View ( UFOV ) subtest 2 ; a Mobility Question naire ; and MVC occurrence . RESULTS In drivers aged 55 and older with intact vision ( 20/70 far visual acuity and 140 degrees visual field ) , age , sex , history of falls , and poorer cognitive performance , as measured using Trails B , MVPT , and UFOV subtest 2 , were predictive of future at-fault MVC involvement . After adjusting for annual mileage , participants aged 78 and older were 2.11 as more likely to be involved in an at-fault MVC , those who made four or more errors on the MVPT were 2.10 times as likely to crash , those who took 147 seconds or longer to complete Trails B were 2.01 times as likely to crash , and those who took 353 ms or longer on subtest 2 of the UFOV were 2.02 times as likely to incur an at-fault MVC . Older adults , men , and individuals with a history of falls were more likely to be involved in subsequent at-fault MVCs . CONCLUSION Performance-based cognitive measures are predictive of future at-fault MVCs in older adults . Cognitive performance , in particular , is a salient predictor of subsequent crash involvement in older adults . High-risk older drivers can be identified through brief , performance-based measures administered in a MVA setting
