Interventions and Outcome Measures

Arms

experimental: Newly designed computer monitor

Participants will read a short story and then watch moving images for 30 minutes or until any of their persisting concussion symptoms arise. The number and severity of symptoms will be assessed by completing SCAT -III pre- and post-study tasks.

sham comparator: Standard computer monitor

Same participants will read a short story and watch moving images for 30 minutes or until any of their persisting concussion symptoms arise on the standard computer screen.The number and severity of symptoms will be assessed by completing SCAT -III pre- and post-study tasks.

Interventions

New computer monitor

The device to be studied is a newly designed computer monitor and will be compared with the standard computer monitor.

Primary outcome measure

  • The investigators believe that patients will subjectively perceive the new monitor to be a more effective reading device than the standard monitor. [ Time Frame: Two visits 7 to 10 days apart ]
