Postural Control, Sleep Quality, and Body Composition in Patients With Ménière’s Disease: A Cross-sectional Study Using Dynamic Posturography

OBJECTIVE: To examine the relationship between postural control, sleep quality, and body composition in patients with Ménière's disease (MD) compared with controls, and identify predictors of balance. STUDY DESIGN: Cross-sectional case-control study conducted January to July 2024. SETTING: University research laboratories specializing in rehabilitation. PATIENTS: Forty-two adults (21 with MD, 21 age- and sex-matched controls). Exclusion criteria included multiple vestibular diagnoses, neurological or psychiatric disorders, and uncorrected visual impairment. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Postural control (Sensory Organization Test, Limits of Stability, Rhythmic Weight Shift), sleep quality (Pittsburgh Sleep Quality Index, Insomnia Severity Index), and body composition (bioimpedance: BMI, fat mass, fat percentage, visceral fat). RESULTS: MD patients showed significantly poorer sleep than controls (PSQI: 9.8 vs. 4.5; mean difference 5.3; P
