Ocular vestibular evoked myogenic potentials: a comparison of 500 Hz toneburst and narrowband CE-Chirp stimuli in older children

To compare ocular vestibular evoked myogenic potential (oVEMP) response parameters in children using a 500 Hz narrowband CE-Chirp stimulus versus a 500 Hz toneburst stimulus.

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

Clinicians using oVEMP testing in older children should note that stimulus type (500 Hz CE-Chirp vs. toneburst) may affect response parameters; verify local normative data before adopting the CE-Chirp in paediatric protocols.

✦ Why It Matters ✦

Establishing whether CE-Chirp stimuli are interchangeable with tonebursts for oVEMP in children is necessary before labs can safely switch protocols or pool data across studies.

✦ Key Points ✦

01oVEMP response parameters were compared between 500 Hz narrowband CE-Chirp and 500 Hz toneburst stimuli in older children.
02CE-Chirp stimuli are newer and may offer different neural synchrony advantages over tonebursts.
03Published ahead of print in International Journal of Audiology.
04Results will inform whether stimulus types are interchangeable in paediatric vestibular assessment.
05Normative paediatric oVEMP data for CE-Chirp stimuli remain limited.
