Influence of bone conduction transducer type and placement on ocular and cervical vestibular evoked myogenic potentials

Abstract Evaluating the effectiveness of different bone conduction (BC) transducers with controlled coupling force to elicit cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) in healthy subjects by comparing response rates, amplitudes, latencies, thresholds and asymmetry rat...
