Limited Interaction Between Vision and Proprioception on Centre of Pressure, Pelvis and Head Positions During Ankle or Neck Vibration in Walking: An Experimental Study

This study investigated the influence of vision and proprioception during walking by manipulating visual information (eyes open, dim light and eyes closed) and proprioceptive information (neck and ankle vibration). Under these specific experimental conditions, no clear interactive effects between vision and proprioception were observed. Instead, their contributions appeared at distinct moments of the stance phase: both modalities influenced gait control at heel contact, neck proprioception effects were more pronounced at midstance, and vision contributed more strongly at toe-off. These findings enhance understanding of sensory contributions during walking and support further exploration of vibration application protocols.
