Purpose The purpose of the investigation was to determine whether the “belly–tendon” electrode derivation produced ocular vestibular evoked myogenic potentials (oVEMPs) in children that were superior to those recorded with the infraorbital–chin electrode derivation. Method This was a prospective observational study using a sample of convenience at a tertiary care medical center. Subjects were 13 children between the ages of 5 and 12 years. We compared the latency of the N1 wave and the N1–P1 peak-to-peak amplitude for the belly–tendon electrode derivation to the infraorbital–chin electrode derivation. Results The belly–tendon electrode derivation was associated with superior N1–P1 amplitudes compared to the infraorbital–chin electrode derivation. However, the large amplitude was also associated with greater variability compared to the infraorbital–chin derivation. There were no significant electrode derivation–based differences in N1 latency. Additionally, there was no predictable relationship between age and oVEMP amplitude. Conclusion As shown previously in adults, the belly–tendon electrode derivation produces significantly larger oVEMP amplitudes compared to the infraorbital–chin electrode derivation.
