Initial Vestibular Function May Be Associated with Future Postural Instability in Parkinson’s Disease

Backgrounds: We aimed to understand the association between initial vestibular function examination and postural instability (PI) development in Parkinson’s disease (PD). Methods: After screening 51 PD patients, we divided 31 patients into 2 groups based on the presence of PI at the follow-up visit...

Sumario:Backgrounds: We aimed to understand the association between initial vestibular function examination and postural instability (PI) development in Parkinson’s disease (PD). Methods: After screening 51 PD patients, we divided 31 patients into 2 groups based on the presence of PI at the follow-up visit and compared the clinical features and vestibular-evoked myogenic potential (VEMP) variables. Results: The mean values of Hoehn and Yahr stage, Unified Parkinson’s Disease Rating Scale (UPDRS) part III, and item 30 (postural stability) of UPDRS were larger in patients with PI at a follow-up visit (p = 0.000, 0.006, 0.048, respectively). In VEMP analyses, the onset latencies of left and right cervical VEMPs were significantly reduced in patients with PI (p = 0.013, 0.040, respectively). Conclusion: We found that the initial VEMP test may be associated with later postural imbalance in PD, suggesting the baseline evaluation may help predict future PI occurrence. A more significant number of patients and more long-term follow-ups are likely to be required for confirmation.
