Test-retest reliability and responsiveness of gaze stability and dynamic visual acuity in high school and college football players.

Objectives: The purpose of this study was to establish reliability and responsiveness of the dynamic visual acuity test (DVAT) at head speeds of 150-200 degrees per second (deg/s) and the gaze stabilization test (GST) in high school and college football players.

Design: Reliability design.

Participants: Fifty high school and college football athletes completed the DVAT and GST in both the yaw (horizontal) and pitch (vertical) planes twice within two weeks.
