Some studies have suggested that hearing loss is a risk factor for postural instability and falls. To explore this association, Korean researchers conducted this study of nearly 4000 participants (age, ≥40; mean, 58) in a cross-sectional, population-based health survey. Each participant underwent pure-tone audiometry and a modified Romberg postural instability test. The latter test involves standing first with eyes open, and then with eyes closed, on a thick polyurethane foam pad; postural instability — defined as inability to maintain balance while standing on the pad for at least 20 seconds with eyes closed — was identified in 3.3% of participants.
After adjustment for age and sex, participants who had at least moderate hearing loss in one…
