Dynamic Visual Acuity test while walking or running on treadmill: reliability and normative data

Rapid head movements are part of everyday life during which gaze needs to be stabilized to ensure visual acuity (VA) [1 –3]. The vestibulo-ocular reflex (VOR) serves as the primary control system for gaze stabilization during head movements at or above 2 Hz by managing contractions of the extra-ocular muscles to keep the eyes fixed on the visual target [2,3]. These compensatory eye movements are essential for cor recting retinal slip, which is the degree of motion of the image across the retina causing decreased visual acuity [1–3].
