PURPOSE: The purpose of this study was to evaluate postural control in adults with age-related hearing loss (ARHL) by adding a variation of a 30° lateral head tilt for each measure. METHOD: Individuals between the ages of 50 and 70 years were recruited (10 with normal hearing, 32 with ARHL) and evaluated using pure-tone audiometry, vestibular function assessments, and postural control measures. Vestibular function assessments used were video head impulse test (vHIT), cervical vestibular evoked myogenic potentials (VEMPs), and ocular VEMPs. Postural control measures used were single leg stance (SLS), Romberg on foam (RF), and tandem walking (TW). Pearson correlation and linear regression were used to evaluate the relationship between pure-tone average, vestibular function assessments, and postural control measures. RESULTS: Results revealed significant correlations between ARHL and cervical VEMPs and ocular VEMPs. As ARHL increased, amplitude of cervical and ocular VEMPs decreased. There were no significant correlations for ARHL and vHIT gain. SLS with lateral head tilt was significantly associated with ARHL. As ARHL increased, the time for SLS with lateral head tilt decreased. There were no significant findings for ARHL and SLS without lateral head tilt, TW with and without lateral head tilt, or RF with and without lateral head tilt. CONCLUSIONS: The results of this study described the decreased postural control with lateral head tilt present as ARHL increased. Furthermore, this study supported the previously documented vestibular degradation that is present in the ARHL population compared to normal hearing. This study suggested that the postural control measure most sensitive to detecting reduced postural control in individuals with ARHL was SLS with lateral head tilt. Further study is needed to hone the specific parameters of using SLS with lateral head tilt as a screening measure to assess risk of falls in the ARHL population.
