EYE-TRAC Advance: Technology Verification (ETA-TV) Cohort 2

Study Overview
=================
Brief Summary
-----------------
This is a prospective multi-center cohort feasibility and exploratory study.

Detailed Description
-----------------
Investigators propose to prospectively study a cohort of 18-25-year-old athletes to establish the reliability of EYE-SYNC data and the utility of the EYE-SYNC eye-tracking device as a sideline concussion assessment tool. The clinical research study will be conducted to 1) determine if eye-tracking, assessed on the sideline by EYE-SYNC eye-tracking device, is a potential marker of injury that can be used in conjunction with other sideline evaluations to inform decisions regarding removal of athletes from play and 2) to use the EYE-SYNC goggle data as a post- injury recovery monitor.

I. Double Leg Stance: At least 3 errors II. Single Leg Stance: At least 3 errors with either dominant or non-dominant foot III. Tandem Stance: At least 3 errors or more. Balance (Tandem Gait): FAIL on at least 2 of 4 trials: I. FAIL per trial: more than 14 seconds to complete a trial II. FAIL per trial, if one or more of the following errors are made If step off the line; Separation between heel and toe Touch/grab the examiner or an object D) Orientation: Score = 0 on any of the following 5 items Date: Score = 0 (any date different from current) Month: Score = 0 (any month different from current) Day of the week: Score = 0 (any different from current) Year: Score = 0 (any different from current) Time: Score = 0 AND answer is MORE than + or - 1 hour apart from the correct time. E) Immediate Memory Recall Total Score = less than 13 words recalled. Exclusion Criteria: Clinical diagnosis of a neurological condition including the following: Stroke, Multiple Sclerosis, Epilepsy, Brain Tumor/Cancer, Nystagmus and/or Other major neurological condition. Clinical diagnosis of any of the following eye-sight abnormalities: Uncorrected Amblyopia, Uncorrected Myopia, Uncorrected Presbyopia, Uncorrected Farsightedness, or Uncorrected Astigmatism. Psychiatric history with any of the following: Clinical diagnosis of a psychotic disorder, bipolar disorder - lifetime Clinical diagnosis of ADHD or ADD - Lifetime Clinical diagnosis of major depressive disorder - within last year Clinical diagnosis of substance abuse disorder - within last year Clinical diagnosis of major anxiety disorder - within last year MEDICATION Requires use of a psychotropic medication. Cannot have participated previously in any of the ETA-TV study visits (for instance, a subject that has completed any study visit as a control subject cannot participate as a concussed subject at a later time point).
