After suffering a stroke, driving a car may be challenging due to vision problems, weakness and loss of coordination. But a study finds that three simple tests done in a doctor's office could be effective at deciding who's going to be safe behind the wheel.
The study was a meta-analysis of 30 studies involving 1,728 men and women, average age 61. Among those, 54% passed an on-road evaluation.
After analyzing the studies, researchers found that three simple tests done in a doctor's office may be used to determine how well someone does behind the wheel following a stroke. Those three tests are a road-sign recognition test, which examines traffic knowledge and visual comprehension; a compass task that tests visual-perceptual and visual-spatial skills and mental speed; and the Trail Making Test B, which assesses visual-motor tracking and visual scanning aptitude.
Each test correctly identified 80% to 85% of unsafe drivers, and the authors wrote that a combination of the three tests would offer a better model to determine how stroke victims perform on the road.
