Background and Objective ZThe aim of this study was to investigate and compare the incidence and the characteristics of parameters of cervical vestibular-evoked myogenic potentials (cVEMPs) using air-conducted (AC) and bone-conducted (BC) stimulations in normal subjects. Subjects and Method Twenty-four normal subjects (48 ears) with normal hearing and no previous history of dizziness were included. cVEMP responses were recorded by surface el-ectrodes on sternocleidomastiod muscles in response to AC and BC stimuli sequentially. Variances of parameters, including thresholds, amplitudes and interaural amplitude difference ra-tios (IADR), were analyzed and compared. Results cVEMP responses were clearly observed in all 48 ears in both AC and BC cVE-MP tests. There was no significant difference in latencies (p1 and n1). However, the thresholds in BC cVEMP testing were significantly lower than those in AC cVEMP testing, when compared to the maximum stimulation level. Interaural amplitude difference ratios showed no sig-nificant difference in between the two tests, although amplitudes at maximum stimulation in-tensity in BC cVEMP testing were significantly larger than those in AC cVEMP testing. Conclusion This study shows that BC cVEMP testing shows lower thresholds compared to AC cVEMP testing in normal subjects, suggesting that the threshold value can be used as a parameter in detecting vestibular dysfunction in the clinic. Further studies in patients with vari ous vestibular disorders are needed.
