In Brief:
The goal of this study was to examine age-related changes in multiple vestibular function tests. Eighty subjects (18-80 years) were subjected to an extensive test battery, consisting of sinusoidal harmonic acceleration tests (SHAT), pseudorandom rotation tests (PRRT), velocity step tests (VST), caloric tests, and vestibular evoked myogenic potentials (VEMP). No significant age trends could be demonstrated with the SHAT and VST, compared to subtle gain decreases with increasing age for the PRRT. Increasing slow component velocity values were measured with the caloric test. Largest age changes were detected with the VEMP, where decreasing amplitudes, increasing thresholds and decreasing N1 latencies were most prominent.
