Summary

Whiplash survivors with abnormal eye movements show impaired driving performance. These visual disturbances, linked to posture control issues, may affect daily functions like driving safety.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Human Factors

Background:

  • Previous research indicates altered eye movements in individuals with chronic whiplash-associated disorders.
  • These oculomotor changes are hypothesized to stem from disruptions in the postural control system.

Purpose of the Study:

  • To investigate if disturbances in eye movements, following whiplash injury, impact daily life functions, specifically car driving.
  • To assess driving performance in individuals with whiplash-related eye movement abnormalities using a driving simulator.

Main Methods:

  • A cohort of 23 individuals with whiplash-induced eye movement disturbances was compared to a matched control group.
  • Participants completed a driving simulation task assessing response times, sign identification, and steering precision.

Main Results:

  • Significant differences were observed between groups in response times to traffic signs and identification accuracy.
  • Steering precision was notably reduced in the whiplash group when attention was focused on sign identification.
  • While controlling for factors like pain and medication, these performance deficits persisted.

Conclusions:

  • Disturbances in the posture control system, leading to abnormal eye movements, are likely primary contributors to impaired driving skills after whiplash.
  • Reduced attentional capacity may act as a secondary mediating factor.
  • Oculomotor assessments could serve as a valuable diagnostic tool for evaluating driving competence post-whiplash.
