Issue Date: | 2024 | Publisher: | WILEY | Source: | Otolaryngology and head and neck surgery, | Status: | Early view | Abstract: | ObjectiveChronic dizziness after acute unilateral vestibulopathy (AUVP) causes significant social and economic burdens. This study aims to identify predictors of chronic dizziness. Study DesignProspective, longitudinal cohort study. SettingENT departments from secondary and tertiary hospitals. MethodsParticipants meeting the Barany Society's diagnostic criteria for AUVP were included. Evaluations occurred within 0 to 21 days (T1), and at 4 (T2) and 10 weeks (T3) postonset. The primary outcome measure was the Dizziness Handicap Inventory (DHI) at 6 months, with a score >30 indicating chronic dizziness. Five clusters of predictors were assessed at T1-3: central vestibular compensation, visual dependence, movement exposure, psychological factors, and balance performance. Separate linear regression models for T1, T2, and T3 were constructed to explain the variability in the 6-month DHI score. Receiver operating characteristics analyses were conducted to predict chronic dizziness. ResultsFrom June 2021 to January 2024, 103 participants (55.2 +/- 16.6 years old, 49 women) were included. The regression models explained the variability in the 6-month DHI score by 33.0% at T1, 47.6% at T2, and 64.0% at T3 (P < .001), including psychological factors (T1, T2, T3), visual dependence (T2, T3), and static balance performance (T3). Cutoff values for the Vestibular Activities Avoidance Instrument (23/54), Visual Vertigo Analog Scale (33.5/100), and Hospital Anxiety and Depression Scale-Anxiety (7.5/21) at 10 weeks postonset predicted chronic dizziness. ConclusionHigher psychological burden, increased visual dependence, and poorer static balance performance were associated with chronic dizziness. Cutoff values were determined to identify individuals with AUVP at risk for chronic dizziness. | Notes: | Van Laer, L (corresponding author), Univ Antwerp, Fac Med & Hlth Sci, Dept Rehabil Sci & Physiotherapy Movant, Antwerp, Belgium. lien.vanlaer@uantwerpen.be |
