Balance performance when responding to visual stimuli in patients with Benign Paroxysmal Positional Vertigo (BPPV)

Research output: Contribution to journalArticlepeer-review

Abstract

BACKGROUND: Patients with Benign Paroxysmal Positional Vertigo (BPPV) often report a sensation of disequilibrium before treatment with the canalith repositioning maneuvers. Apart from vestibular information, visual input also contributes to balance control. How visual stimuli influence balance control in BPPV patients is unclear. OBJECTIVE: To investigate the influence of visual stimuli on balance performance in BPPV patients. METHODS: Three groups of participants, patients with BPPV, and healthy young and older adults, were instructed to stand under three conditions: 1) eyes open (EO); 2) while watching a static picture via a video display; and 3) while watching a rotating visual scene. Antero-posterior (AP), lateral (ML), and total sway path during standing were analyzed. RESULTS: In all conditions, patients with BPPV showed significantly larger AP, ML and total sway path than young, whereas older adults only showed significantly larger AP and total sway path than young adults. During the visual stimuli, all participants exhibited significantly increased AP and total sway while watching a static image and a moving scene as compared with the EO condition. CONCLUSIONS: Patients with BPPV have similar balance control to older adults, but poorer balance control than young adults. The reduced lack of standing balance control in the coronal plane of patients with BPPV, might affect balance strategy after external perturbations.
