Abstract

Background/Objectives: Persistent Postural Perceptual Dizziness (3PD) is a syndrome unifying related chronic dizziness disorders. Our research aims to understand how changes in visual stimuli affect standing postural control or balance strategies of participants. Methods: Three patients with 3PD and four controls participated in this study. An external perturbation device was utilized to perturb standing posture during various visual perceptual conditions while an instrumented force platform recorded Center of Pressure (CoP) data. Results: Greater peak posterior COP displacement was recorded with eyes closed for those with 3PD. Conclusion and Discussion/Implications: Those living with 3PD may have reduced postural control
