Optimizing Ocular Vestibular Evoked Myogenic Potentials With Narrow Band CE-Chirps

Objectives:

To evaluate the effects of narrow band CE-Chirp (NB CE-Chirp) on the amplitudes and latencies in ocular vestibular evoked myogenic potentials (oVEMPs) at 500 and 1000 Hz in comparison with tone burst (TB).

Design:

Twenty-one healthy volunteers were included in the study and tested in air conduction with a “belly-tendon” montage. Recording conditions were randomized for each participant and each modality was tested twice to check the reproducibility of the procedure.

Results:

NB CE-Chirps at 500 Hz revealed larger n1-p1 amplitudes than 500 Hz TBs (p = .001), which were also larger than NB CE-Chirps and TBs at 1000 Hz (p = .022, p
