Short Communication: The Belly--Tendon Derivation Yields Superior Ocular Vestibular Evoked Myogenic Potential Amplitudes in a Normal Pediatric Sample.

摘要

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.
