Resilience of visually guided weight shifting to a proprioceptive perturbation depends on the complexity of the guidance stimulus.

Background: Whole-body tracking of visual motion cues is used in balance training to improve weight shifting ability in old age and sports.

Research Question: How tracking of a complex (pink noise) and a periodic visual target motion during anteroposterior weight shifting affects postural and muscle responses to unilateral hip vibration.

Methods: Twenty-six participants performed 160 anteroposterior weight shifting cycles while tracking the vertical motion of a visual target, concurrently receiving Center of Pressure (CoP) feedback.
