Who Can Drive After a Stroke? Tests Can Help Decide

21.02.2011
Many people want to keep driving after having a stroke, and many can do so safely. Simple tests in the office can help doctors determine who is more likely to be a safe driver after a stroke, according to research published in the February 22, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology.

The research analyzed all of the available studies on driving after a stroke. In all of the studies, participants’ driving skills were tested in an on-road evaluation.

A total of 30 studies were analyzed. There were 1,728 participants with an average age of 61 in the studies. Of those, 938, or 54 percent, passed the on-road evaluation. The average amount of time between the stroke occurring and the on-road evaluation was about nine months.

Three tests can be used to identify those people who are most at risk of failing the on-road driving test.

“These are simple tests that can be done in the doctor’s office, which is important because on-road tests are time-consuming and expensive,” said study author Hannes Devos, MSc, of Catholic University of Leuven in Belgium. “These tests are readily available and can be administered within 15 minutes.”

The tests are a Road Sign Recognition test that assesses traffic knowledge and visual comprehension, a Compass task that examines visual-perceptual and visual-spatial abilities and mental speed, and the Trail Making Test B, which measures visual-motor tracking and visual scanning abilities.

People who score below 8.5 out of 12 on the road sign test, below 25 out of 32 on the compass test and take more than 90 seconds to finish the trail making test are more likely to fail the on-road evaluation. The tests correctly classified 80 to 85 percent of the unsafe drivers.

The results also showed that participants’ fitness to drive could not be predicted by their motor symptoms. “This is not surprising considering the wide range of adaptive devices that are available, such as steering knobs that can be operated by one hand and left-foot accelerator pedals for people with limited use of the right leg,” Devos said.

In addition, the analysis found that three out of four studies showed no increased risk of accidents for people cleared to drive after a stroke.

The American Academy of Neurology, an association of more than 22,500 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
