  1. Prediction of Return to Driving Post-CVA: An Evidence-Based Review Presented by Melissa Arakelian

  2. Introduction… • Currently CVA is the most frequently encountered diagnosis by occupational therapists in the adult setting • Leading cause of disability in the U.S. • Driving is relatively new problem faced by clinicians • Identified as one of top 10 emerging practice areas by The American Occupational Therapy Association (AOTA)

  3. Impact of Driving… • Clients often identify driving as the most important IADL • Viewed, within our culture, as a symbol of independence and adulthood • Greater incidence of depression noted in non-drivers • Decreased participation in social activities

  4. Defining OT Roles… Occupational Therapy Generalist: Possess general knowledge and understanding of performance and processing skills related to driving. Occupational Therapist with Advanced Training: Further educated to evaluate the integration of sub-skills associated with driving, and provide specific sub-skill training. Occupational Therapist with Specialized Training:Received specialized education, examination, and/or certification.

  5. Occupational Therapy Generalist… • Expected to have greatest knowledge of expertise among team members • Responsible for clinical evaluation of sub-skills necessary for driving • Knowledgeable of driving programs and resources available

  6. Physical Abilities Perceptual skills Cognitive abilities Vision Attention Emotion Reaction Time Mobility Hearing Visual Attention Planning/Problem Solving Physical and Mental Endurance Information Processing Speed Visual Memory Visuocognitive abilities Visual Attention Visuomotor coordination In order to Drive…

Trail Making Test (Part A) Visual Form Recognition Test Single and Double-Letter Cancellation Cognitive Behavioral Driver’s Inventory (CBDI) Dynavision Assessment Battery (DPAB) Bells Test Motor-Free Visual Perception Test TMT-A and TMT-B UFOV (useful field of vision) Complex Reaction Timer Money Road Map of Direction Test Charron Test Assessments Currently Employed…

  8. Where to Focus… Currently there are no universally accepted clinical guidelines defining what constitutes a complete assessment battery for determining the ability to return to driving General clinical evaluation should consist of • Vision • Perceptual skills • Cognitive skills

  9. Vision… • An estimated 90% of informational input received during driving is visual • Necessary to evaluate basic visual skills first…

  11. Vision… In a study by Fisk, G. D., Owsely, C., & Mennemeier, M. (2002), impairment of visual attention measured by the UFOV indicated greater impairment among post-stroke non-drivers versus post-stroke drivers Useful Field of Vision (UFOV) : Test of visual attention, measuring information processing, ability to divide attention, and the speed of processing

  12. Perceptual Skills… Mazer, B., Korner-Bitensky, N. A. & Sofer, S. (1998) assessed the ability of the following perceptual tests to predict on-road driving outcomes: • The Complex-Reaction Timer • Motor-Free Visual Perception Test (MVPT) • Single & Double Letter Cancellation Tests • Money Road Map Test of Direction Sense • Trail Making Test A and B • Bells Test • Charron Test

  13. Perceptual Skills… Findings by Mazer, B., Korner-Bitensky, N. A. & Sofer, S. (1998): • MVPT found to have the highest positive and negative predictive ability • Logistic model found best at predicting on-road driving outcomes included use of the MVPT and Trail Making B tests • Reaction time noted as near significance in prediction

  14. Cognitive Skills… • Research indicates neuropsychological testing of executive functions should be included in pre-driving assessment • Klavora, P., Heslegrave, R. J., & Young, M. (2000) compared the effectiveness of Cognitive Behavioral Driver’s Inventory (CBDI) and the Dynavision Performance Assessment Battery (DPAB) • Only the Endurance Dynavision Task (EDT) and the CBDI were found significant in predicting on-road outcomes

  15. Additional Off-Road Tests… • Implementation of simulators in clinical evaluation • Able to provide face-valid context for observing driving behaviors • Study by Lee, H. C., Lee, A. H., & Cameron, D. (2003) validated the use of the STISIM Driving Simulator for assessing visual attention

  16. Impact of Off-Road Tests… • Cost Effective • Less intimidating to client • Safer form of evaluation • Allow for task break down, assessing performance of driving sub-skills

  17. In Summary… • Driving is an IADL, and within the scope of practice for occupational therapists • General clinical evaluations of driving should include standardized assessment of visual, perceptual, and cognitive skills • Impossible to determine ability to return to driving using one assessment tool • Clinical evaluation should be followed by on-road testing prior to judgment of driving ability
