Objectives
• Understand how impairments common to stroke impact driving
• Be familiar with guidelines and responsibilities related to driving
• Describe the approach to screening, assessment and remediation
• Become aware of local services• Be familiar with common vehicle adaptations to support
return to driving
3
Incidence of Stroke
50 000 Canadians suffer the effects of a stroke each year. (Heart and stroke)
70% of survivors will have residual perceptual and cognitive dysfunctions. (Heart and Stroke)
30% of stroke survivors with moderate to severe stroke will return to driving. (Marshall, S., et.al.)
87% of those returning to driving have not received any formal evaluation of driving ability. (Marshall, S., et.al.)
The crash rate for drivers post-stroke was nearly three times the risk of crash involvement compared to healthy, older drivers. (Perrier, M., Korner-
Bitensky, N., Petzold, A., and Mayo, N., 2009)

Impact of Stroke on Driving Performance
Language comprehension

Sensory and Motor Functions
7
Red flags• Forgetting familiar routes, getting lost
• Stopping in traffic when there is no need to stop due to demands on complex or fast cognitive processing
• Confusion between pedals in a stressful situation
• Failing to yield right-of-way appropriately
• Easily frustrated or confused while driving
• Drift across lane markings into other lanes
• Difficulty thinking clearly about the traffic around you

Whose Responsibility is it?
Driver’s license holder
A person who holds or applies for a driver’s license must immediately disclose to the Registrar a disease or disability that may interfere with the safe operation of a vehicle.
The presence of a related medical condition does not necessarily mean that a person’s ability to drive will be restricted.
9
Whose Responsibility is it?Driver Fitness and Monitoring
Is a program/service within the Government of Alberta’s Ministry of Transportation.
Responsible for reviewing driving privileges of individuals and assessing their ability to safely operate motor vehicles.
The final decision pertaining to whether a person loses the privilege to drive is up to Driver Fitness and Monitoring.
10
Whose Responsibility is it?
Health Care Professional
Identify
Advocate
Report
Assessment
Remediation “Why can’t you people get organized?” One day you take my license away and the next
day you ask to see it.”
11
CCMTA Licensing Guidelines
• Canadian Council of Motor Transport Administrators
• Guidelines relate to specific medical conditions for a class 5 license
• Cerebrovascular diseases start on page 19
For full guidelines see www.ccmta.ca
12
Stroke
Patients should not drive for at least one month.
Driving may resume if:
No significant motor, cognitive, perceptual or visual deficits. Where there is loss of function and ability, a road test is recommended.
Neurological assessment discloses no obvious risk of sudden recurrence.
Underlying cause has been appropriately treated.
No post stroke seizure has occurred.
13
Cerebral Aneurysm
• Symptomatic aneurysm is an absolute barrier to driving any vehicle.
• In case of an asymptomatic, incidentally discovered aneurysm, the driver may be eligible for any class of licensure upon receipt of a favourable opinion from a neurologist/neurosurgeon.
• Surgically treated cerebral aneurysm warrants a waiting period of 3 months private driving, 6 months commercial driving
14
Single or Recurrent TIA
Should not be permitted to drive until:
• A neurological assessment and appropriate investigations
are completed.
• May resume if the neurologic assessment shows no
residual loss of functional ability, discloses no obvious risk
of sudden re-occurrence and any underlying causes have
been addressed with appropriate treatment.
15
Seizures or Epilepsy
Class 5 or 6 if • free from seizures for six months, provided
medication prescribed does not cause significant side effects that would impair driving
AND• the physician believes the individual is being truthful
about the frequency of seizures, will take medication in the manner prescribed and is under regular medical supervision
16
Visual Acuity
• Not less than 20/50 both eyes open
and examined together
• Must at least be such that there is
time to detect and to react to
obstacles, pedestrians, other
vehicles and signs.
17
Visual Field Deficits
• If a visual field deficit is suspected, the patient should be referred to an ophthalmologist or optometrist for further testing
18
Visual Field Deficits
• Complete homonymous or bitemporal hemianopsia -
suspended from all driving privileges
• 120 continuous degrees along the horizontal meridian
and 15 continuous degrees above and below fixation
with both eyes open and examined together.
19
So…how do we screen and assess?
20
CCMTA Best Practice Strategy
• Individual assessment strategy for safe return to driving
• Specifically for vision loss, although process is similar post-stroke
• OT specific model for driving to be published in Jan/Feb 2011 (AJOT)
21
Approach to Driving Assessment
In house– Clinical based assessment usually focused on
assessment of cognitive, perceptual and other skills believed to impact on driving ability
On road– Actual driving assessment – Often seen as gold standard but issues exist related
to lack of structure, standardization, reliability and validity
22
MMSE
• MMSE Routinely used to assess driving ability with a cut off of 24/30
• Not designed for this application• Low specificity
– Proportion of clients who were predicted to pass an on road test based on a cut off of 24/30, who did pass, was low (Dobbs and Schopflocher, 2010).
23
SIMARD MD
• Paper and pencil screening tool for identifying cognitively impaired drivers
• Used by health care professionals and driver licensing agency personnel
• Composed of four subtests
• Early, but has some promising applications to predict on road performance in some situations…lacks adequate research!
24
Bottom Line
Nothing predicts on road performance but....
On road evaluation!

Compensatory Strategies
Adaptive equipment can compensate for some physical impairments in the absence of cognitive impairments

42
Impact of driving cessation
Negative psychological, social and functional implications associated with driving cessation
Driving represents freedom, control and independence. • Go where you want, when you want
Mobility is a right, driving is a privilege. What are the alternatives if driving cessation is necessary?
Process of acceptance and grieving for license loss is individual
43
Stay SHARP program• McGill University initiative – currently funded for a phase
1 pilot study
• Acronym Stay SHARP (See, Hear, Attend, Respond, Perform) (Korner-Bitensky, N. & Kua, A., 2010).
• Includes retraining focused on– Physical and behavioral skills– Visuo-spatial and cognitive skills– Driving specific knowledge.
Funded by CIHR/Candrive
