Select Physical Performance Measures and Driving Outcomes in Older Adults

Select Physical Performance Measures and Driving Outcomes in Older AdultsThis systematic review assesses the evidence in the research literature on the association between three well-validated lower extremity physical functioning measures with driving outcomes in older adults.

In current aging research, only one well-validated and reliable physical functioning battery (the Short Physical Performance Battery [SPPB]) is being used consistently, although there are multiple stand-alone measures that are regularly employed, including the Timed Up and Go Test (TUG) and the Rapid Pace Walk (RPW).   Lower SPPB scores are associated with reduced driving exposure and increased cessation, poorer RPW scores are associated with decreased driving ability in some studies and reduced driving exposure in one study, and TUG scores are not associated with any driving outcomes. The TUG measure does not appear to be a useful measure of physical functioning for the driving outcomes that were included here, although the studies were limited. The RPW may be useful in studies related to driving ability and exposure.

More driving studies should consider using the SPPB to determine if there is an association between SPPB scores and driving outcomes that have not been studied with this battery, and the SPPB may be useful as a risk factor assessment for identifying individuals at risk of reducing their driving exposure and driving cessation.
