Our aim is to compare short tone burst (STB)-and clicks-stimuli to evoke vestibular-evoked myogenic potentials (VEMPs) in healthy controls. A cross-sectional study in which VEMPs were measured in two sets of 185 and 55 normal volunteers by an air-conducted 500 Hz STBs and clicks, respectively. The test-retest reliability between different sessions was assessed in two subsets of 35 individuals. Moreover, 53 individuals were examined with both stimuli within the same session. Intraclass correlation coefficients (ICC) were used to assess reliability for P1 and N1 latencies, corrected amplitude and asymmetry ratio (AR). The results included that STBs produced a reliable response between different sessions (N = 35; [ICC] = 0.61-0.94, all p < 0.0001). Although clicks produced a reliable response for P1 and N1 latencies and corrected amplitudes (ICC = 0.62-0.74, all p < 0.0001), the amplitude ratio showed a lower reliability [ICC = 0.32 (-0.10 to 0.59)]. The amplitude of VEMP was consistently larger with 500 Hz STBs than clicks for a given sound pressure level. Within the same session, STBs evoked a response in 52/53 subjects (98%) whereas clicks evoked VEMPs only in 44/53 individuals (83%). Conclusions revealed that a 500 Hz STBs elicited consistently larger amplitudes, better reliability across recording sessions and fewer missing responses compared with click-induced VEMPs.
