Summary
This study establishes normal cervical vestibular evoked myogenic potential (cVEMP) values for children aged 8-13. These findings provide essential benchmarks for assessing vestibular function in pediatric neurotology.
Area of Science:
- Neuroscience
- Audiology
- Pediatric Medicine
Background:
- Cervical vestibular evoked myogenic potential (cVEMP) assesses vestibular function via acoustic stimulation.
- Established adult standards exist, but pediatric data is limited.
- cVEMP activation involves the saccular macula and muscular response.
Purpose of the Study:
- To determine normative standards for cVEMP in children.
- To provide reference values for pediatric neurotological examinations.
- To aid in the diagnosis of vestibular disorders in children.
Main Methods:
- Cross-sectional analysis of 30 healthy children (15 male, 15 female).
- Age range of participants: 8-13 years.
- Data collected on P1 and N2 peak latencies and amplitudes.
Main Results:
- Mean P1 latency: 17.26 ms; Mean N2 latency: 24.78 ms.
- Mean P1 amplitude: 49.34 μV; Mean N2 amplitude: 66.23 μV.
- Mean P1-N2 amplitude: 115.6 μV; no significant gender or laterality differences.
Conclusions:
- Normal cVEMP values for children aged 8-13 years were established.
- These values serve as a reference for neurotological assessments in this age group.
- The study contributes essential normative data for pediatric vestibular function testing.

01:29The Vestibular System
45.2K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:15Equilibrium and Balance
8.1K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
