Agreement, Reliability, and Measurement Error of Cervical Vestibular Evoked Myogenic Potentials in Patients: II. Meta-Analysis and Reliability of Latency and Amplitude

OBJECTIVES: This study assessed the reliability and measurement error of cervical vestibular evoked myogenic potential (cVEMP) latency and amplitude parameters in cochlear implant candidates and synthesized previous reliability evidence through an embedded meta-analysis....

Discussion

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

cVEMP reliability data from this meta-analysis can inform audiologists about expected measurement error ranges when using cVEMP latency and amplitude in cochlear implant candidate evaluations, but practice changes should await local validation of these benchmarks.

✦ Why It Matters ✦

Establishing the reliability and measurement error of cVEMP parameters is foundational for using this vestibular test as a meaningful clinical outcome measure in cochlear implant candidates.

✦ Key Points ✦

01Meta-analysis pooling reliability data for cVEMP latency and amplitude across multiple studies.
02Focused on cochlear implant candidates, a population where vestibular assessment is increasingly important.
03Quantifies agreement and measurement error, providing benchmarks for clinical interpretation.
04Published in Ear & Hearing (2026), a high-impact peer-reviewed audiology journal.
05Findings inform how much change in cVEMP values represents a real clinical difference vs. normal test variability.

✦ Claims & Evidence ✦
