Outcome Measures

Primary Outcomes (1)

  • Stability of Fixation

    The ability to keep eye position fixed on a visual target, measured by the distance between the target and eye fixation point averaged over 20 sec.

    During eye movement recording session (20 sec).

Study Arms (2)

Control

Control subjects with no Mild Traumatic Brain Injury (MTBI) and no Post-Traumatic Stress Disorder (PTSD)

MTBI

Subject with a diagnosis for Mild Traumatic Brain Injury (MTBI)

Eligibility Criteria

Age18 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Adult betwenn 18 and 55 years old with and without a diagnosis of MTBI

You may qualify if:

  • OIF/OEF Veteran;
  • Neuropsych diagnosis of MTBI

You may not qualify if:

  • chronically abusing alcohol or illicit drugs.
  • uncorrected vision prevents subject from effectively viewing the stimuli, unless they can wear contact lenses during the recording session.
  • inability to make normal eye movements (i.e.: saccades, smooth pursuit) required by study paradigms. Note: Deficit can be caused by taking medications that can potentially affect eye movements or any neurological condition that can interfere with making normal eye movement.
  • psychological or psychiatric conditions that preclude sustained concentration or ability to perform the tasks.
