The vestibulo-ocular reflex (VOR) stabilizes the image on the retina when the head moves: the eyes turn in the opposite direction at the same speed. The image remains clear even during a sprint.
These sensors project to the vestibular nuclei, then to the oculomotor nuclei via the MLF. Latency: < 10 ms.
Gain = eye speed / head speed.
VOR exercises (x1, x2) and prismatic glasses can recalibrate gain in just a few days.
Utricle triggers microsaccades to keep the horizon stable during translation (e.g., running).
Without VOR, blurred vision occurs as soon as you walk; posture compensated by rigidity → fatigue. Rehabilitating VOR reduces postural sway by 50% in 6 weeks.
Sixty seconds on one foot, eyes closed, on a foam cushion. The pelvis stays stable, the ankle works finely, the athlete could hold for another minute. Ten minutes later, during a change of direction with a ball and an opponent in contact, the same support slips and the same athlete falls to the ground. Same ankle, same person, same session.
