Abstract
Purpose: To investigate the correlation between vestibular dysfunction and the risk of falls, and the impact of dizziness on the quality of life in older people.
Methods: Cross-sectional, observational, analytical study with a sample of 42 older adults of both sexes with vestibular dysfunction confirmed by vestibular evoked myogenic potential (VEMP) and the Video Head Impulse Test (v-HIT). Subjective balance assessment was also performed using dizziness scales and questionnaires: the Berg Balance Scale (BBS), which assesses the risk of falls; the visual analog scale (VAS), which assesses the degree of discomfort caused by dizziness; and the Dizziness Handicap Inventory (DHI), which assesses the impact of dizziness on quality of life. The examinations, scales, and questionnaire were performed on the same day.
Results: The gain of the semicircular canals was negatively correlated with VAS and positively correlated with BBS. The corrected cervical asymmetry index was negatively correlated with VAS.
Conclusion: Reduced semicircular canal gain and greater asymmetry of the lateral semicircular canals in the v-HIT examination were correlated with a higher risk of falls and greater self-reported discomfort due to dizziness.
