Clinical Assessments as Predictors of Primary On-Road Outcomes in Parkinson’s Disease

Classen, S., Holmes, J., Alvarez, L., Loew, K., Mulvagh, A., Rienas, K., Walton V., & He, W. (2015). Clinical assessments as predictors of primary on-road outcomes in Parkinson’s disease. OTJR: Occupation, Participation and Health, 35 (4), 5-13. DOI: 10.1177/1539449215601118


Clinical predictors of fitness-to-drive in Parkinson’s disease have previously been dichotomized into pass/fail categories. On road assessments, however, may result in two other classifications: pass with remediation or fail-remediable. Results from this study indicated that Trails B, Left Finger to Nose Test, and contrast sensitivity measures were significant predictors for the two passing subgroups.
