Objectives

Narrative objectives1

We measure the eye movement tracking of healthy and cerebral concussion patients, and clarify the method of quantitatively assessing and diagnosing the degree of disability. In this research we will obtain knowledge of disability by cerebral concussion, and of the safety return to competition.

Assessment

Primary outcomes

Eye movement tracking during recovery process after cerebral concussion


1. Athlete
Registration1-1; Register and measure before the season begins
Registration1-2; Registration and measurement during season
Register1-3I; Register and measure after the end of the season

2. Patient
Registration 2-1; Within 3 days of injury, registration and measurement
Registration 2-2; 1-2 weeks after injury symptom hearing and measurement
Registration 2-3; symptom hearing and measurement 1 to 2 months after injury

Key secondary outcomes

1. Eye movement tracking individual differences at non-cerebral concussion
2. Changes in eye movement tracking accompanying cerebral concussion symptomatic transition
3. Verification of validity of stepwise competition return after cerebral concussion
4. Verification of association between cerebral concussion symptoms and eye movement tracking
5. Other adverse events

Interventions/Control_1

LTOG (Limbus Tracking Oculography)
LTOG optically measures the positions of the black eyes by measuring the amount of reflected light by irradiating infrared rays on the white eye and the black eye, and saves the result as a digital data format. LTOG shows a rotation index that makes a constant rotation to make the eyeball perform a parachute (follow-up movement), a method to make the eyeball alternately turn on the LEDs at a distance to make a saccade (leaping movement), stop one point Let the fixation microtremor, which is the fluctuation of the eyeball occurred in the case of the eye movement.
The LTOG device is installed in the darkroom of the sports medicine practice room at St. Marianna University School Gymnasium and in the heart sound room (darkroom) on the 2nd floor of St. Maryanna Medical University Hospital. Measure eye movement by wearing goggles and tracking movement of light by LED lighting. The time required for measurement alone is about 20 seconds per person. It is estimated that it takes about 10 minutes to wear goggles and set up personal computers before and after.

Results

Ocular motility examinations were conducted, and participants were assigned to either the good improvement group (improvement rate over 15%) or the minor improvement group (improvement rate under 15%). SCAT 5 was measured at two points, involving 13 men: eight in the good improvement group and five in the minor improvement group. Symptom number, symptom severity, single-leg stance, tandem stance, and total errors worsened in the minor improvement group.
