Abstract

The purpose was to determine the test-retest reliability and establish reliable change indices for measures of visual and sensory performance in healthy college students. Participants were administered several clinical and research tests of static and dynamic visual acuity, gaze stability, and visual-motor sensory performance 14 days apart. The test-retest ranged from 0.08 to 0.81 across all measures, and some demonstrated significant practice effects. Clinicians should recognize employing reliable change indices is but one method to manage concussed patients, and should consider employing other tools to assess those tests demonstrating the lowest reliability. A secondary purpose was to explore if visual deficits exist in college athletes who have been cleared to return to play following concussion. We were unable to sufficiently power these exploratory analyses. Therefore, subsequent studies should evaluate the sensitivity, specificity, and predictive values of visual performance testing in the context of concussion diagnosis and management.
