BACKGROUND Diffuse and focal traumatic brain injury (TBI) can result in perceptual, cognitive, and motor dysfunction possibly leading to activity limitations in driving. Characteristic dysfunctions for severe diffuse TBI are confronted with function requirements derived from the hierarchical task analysis of driving skill. OBJECTIVE Specifically, we focus(More)
Multi-component models of visual hemi-neglect have postulated that visual hemi-neglect is characterised by various attentional deficits. A grey scales task has been developed to quantify the early, automatic, (perhaps obligatory) ipsilesional orienting of visual attention, frequently assumed as the first of these attentional deficits. Explanations for this(More)
Aims. Homonymous hemianopia (HH), a severe visual consequence of stroke, causes difficulties in detecting obstacles on the nonseeing (blind) side. We conducted a pilot study to evaluate the effects of oblique peripheral prisms, a novel development in optical treatments for HH, on detection of unexpected hazards when driving. Methods. Twelve people with(More)
OBJECTIVES To identify the most accurate clinical predictors of fitness to drive (FTDr) in Huntington disease (HD). METHODS This cross-sectional study included 60 active drivers: 30 patients with manifest HD (8 women) and 30 age- and gender-matched healthy controls. Mean (SD) age of the HD group was 50 (12) years and median (Q1-Q3) disease duration was 24(More)
Parkinson's disease (PD) affects driving ability. We aimed to determine the most critical impairments in specific road skills and in clinical characteristics leading to failure on a road test in PD. In this cross-sectional study, certified driving assessment experts evaluated specific driving skills in 104 active, licensed drivers with PD using a(More)
BACKGROUND No long-term studies have been reported on the effect of training programs on driving after stroke. OBJECTIVES The authors' primary aim was to determine the effect of simulator versus cognitive rehabilitation therapy on fitness-to-drive at 5 years poststroke. A second aim was to investigate differences in clinical characteristics between stroke(More)
BACKGROUND Several driving retraining programs have been developed to improve driving skills after stroke. Those programs rely on different rehabilitation concepts. OBJECTIVES The current study sought to examine the specific carryover effect of driving skills of a comprehensive training program in a driving simulator when compared with a cognitive(More)
OBJECTIVE To determine the driving skill impairments and underlying visual, motor, and cognitive deficits that lead to failure on road testing in manifest Huntington disease (HD). METHODS Certified driving assessment experts scored performance on 13 specific on-road driving skills in 30 persons with HD and 30 controls and issued a pass/fail decision based(More)
BACKGROUND Stroke presents with heterogeneous recovery periods, severity, and manifestation of deficits, all of which may adversely impact fitness-to-drive. Little is known about the association between site of lesion and driving performance after stroke. OBJECTIVE To investigate the association between site of stroke lesion and driving performance.

Previous studies have shown that comorbidities have an impact on driving performance in older adults. No study has established the relationships between comorbidities and driving in persons with Parkinson disease (PD). The aims of this study were (1) to report the types of comorbidity in a group of 111 drivers with PD and (2) to identify whether the(More)
