Classen, S., Brumback, B., Monahan, M., Malaty, I.I., Rodriguez, R.L., Okun, M.S., McFarland, N.R. (2014). Driving errors in Parkinson’s Disease: Moving closer to predicting on-road outcomes. American Journal of Occupational Therapy, 68:77-85; doi:10.5014/ajot.2014.008698
In this study, the authors examined and quantified the on-road driving errors that may predict passing or failing an on-road assessment for drivers with Parkinson’s as well as healthy controls. More drivers with PD failed the on-road assessment than the healthy controls. Errors predicting on-road pass or fail outcomes were visual scanning, signaling, vehicle positioning and speeding.
