Driving frequency in older adults is linked to subtle motor and visual skills. Performance-based assessments can identify deficits impacting driving ability and independence in seniors.

Area of Science:

  • Gerontology
  • Ophthalmology
  • Neurology

Background:

  • Maintaining independence is crucial for older adults, with driving being a key factor.
  • Clinical determinants of driving status in the elderly population remain largely unknown.
  • Driving cessation significantly impacts autonomy and quality of life in later years.

Purpose of the Study:

  • To investigate clinical factors associated with driving frequency in aged male veterans.
  • To identify specific performance-based measures that predict driving status.
  • To understand the role of motor and visual functions in elderly driving behavior.

Main Methods:

  • 143 aged male veterans (mean age 70) were categorized by driving frequency: frequent, infrequent, and rare/non-drivers.
  • A comprehensive performance-based assessment was administered to 116 participants.

  • Stepwise ordinal logistic regression analyzed associations between clinical factors and driving frequency.

    • Main Results:

    • No significant differences were found in age, cognitive testing, or stroke history among driving groups.
    • Significant differences were observed in grip strength, reaction time, static and dynamic visual acuity, and peripheral vision.
    • Dynamic visual acuity, nondominant hand grip strength, and horizontal peripheral visual field predicted driving frequency, explaining 45% of the variance.

    Conclusions:

    • Subtle motor and visual deficits significantly influence driving frequency in the elderly.
    • Performance-based assessments can detect impairments relevant to driving ability.
    • Early identification of these deficits may help maintain driving independence and safety in older adults.
