研究概览
简要总结
This study will assess the effects of exercise and non-concussive bodily contact on eye-tracking scores collected by the EYE-SYNC eye-tracking device.
详细描述
The investigators propose to prospectively study a cohort of 18-25-year-old athletes. Athletes will be tested with the EYE-SYNC eye-tracking device prior to the start of an athletic practice or competition (pre-test) and then after the conclusion of the practice/competition (post-test). The investigators hope to understand if eye-tracking scores are effected by exercise and non-concussive bodily contact commonly incurred during athletic play.

结局指标
主要结局
Changes in the Eye-tracking Score Before and After Practice or Game: Tangential and Radial Error
时间窗: Up to 6 hours
The EYE-SYNC test was performed before and after practice to analyze the effect of exercise and sub-concussive impact. The movement of eye was tracked using EYE-SYNC. The data were recorded in a surface tablet connected to EYE-SYNC. Tangential and radial error are defined as degrees of variation in eye tracking along a circular path (tangential) and at 90 degrees to the tangential path (radial). Positive values indicate the eye is ahead of the target; negative values indicate the eye is behind the target.
Changes in the Eye-tracking Score Before and After Practice or Game: Vertical and Horizontal Gain
时间窗: Up to 6 hours
The EYE-SYNC test was performed before and after practice to analyze the effect of exercise and sub-concussive impact. The movement of eye was tracked using EYE-SYNC. The data were recorded in a surface tablet connected to EYE-SYNC. Vertical and horizontal gain are defined as the ratio of velocity (velocity of the eye:velocity of the target). Positive values indicate the eye is ahead of the target; negative values indicate the eye is behind the target.
Changes in the Eye-tracking Score Before and After Practice or Game: Phase Error
时间窗: Up to 6 hours
The EYE-SYNC test was performed before and after practice to analyze the effect of exercise and sub-concussive impact. The movement of eye was tracked using EYE-SYNC. The data were recorded in a surface tablet connected to EYE-SYNC. Phase error is defined as the difference in degrees between movement of the target and the movement of the eye. Positive values indicate the eye is ahead of the target; negative values indicate the eye is behind the target.
