  1. Measurements will be performed in three different conditions: Sitting, Standing, and Walking. Passive = head movement made by examiner. Active = head movement made by subject (important while standing and walking, as the examiner should not influence the subjects balance and gait). VOR = vestibulo-ocular reflex. Smooth eye-head tracking = vestibulo-ocular reflex suppression test with head-fixed target. “natural” walking = treadmill walking without presentation of visual stimuli (control task). Fixation-/no-fixation = standing or walking 30 s. without fixation of a visual target, standing or walking 30 s. while fixation of a visual target. Rapid eye-head gaze shifts = vestibulo-ocular reflex suppression test while rapid gaze shifts
