“…The current results support and expand the previous findings that reproducible cVEMPs can be recorded in very young children. 3 5 6 7 8 9 10 11 All cVEMPs measures, in the present study, exhibited fairly normal distributions regarding side, age, and sex subgrouping.…”

“…There is ample literature addressing cVEMPs recording in children as young as 2–16 days during natural sleep, 7 9 4 weeks, 10 1–12 months, 5 and ≥ 3 years. 3 6 8 11 To our knowledge, no studies are concerned with cVEMPs recording during the age range of 1 to 3 years, the period in which walking difficulties appear in children. In a trial to overcome the difficulty in cVEMPs recording in very young children who cannot follow the instructions of the examiner, the current study was designed to test the producibility of cVEMPs under sedation, while assuming a head position that maintains the SCM contracted and to set the normative values of the latencies, the amplitude, and the amplitude ratio.…”

“…These findings are in agreement with the earlier cVEMPs research outcomes. 3 8 11 The vestibulo-collic reflex generating the cVEMPs response originates from the lower brainstem, which has a little laterality effect. Consequently, the symmetry of the data indicates the coordinated activity of the vestibular system on both sides.…”

Introduction Cervical vestibular-evoked myogenic potentials (cVEMPs) are difficult to test in toddlers who cannot follow instructions or stay calm. Objective Due to the growing need for vestibular testing in very young children as a part of a delayed walking assessment battery, this study aimed to provide a solution to this problem by recording the cVEMPs in toddlers during sedation. Method The cVEMPs measures were assessed in 30 toddlers aged 12 to 36 months with normal motor milestones. They were sedated with chloral hydrate. Then, the head was retracted ∼ 30° backward with a pillow under the shoulders, and turned 45° contralateral to the side of stimulation to put the sternocleidomastoid (SCM) muscle in a state of tension. Results The P13 and N23 waves of the cVEMPs were recordable in all sedated toddlers. The cVEMPs measures resulted in the following: P13 latency of 17.5 ± 1.41 milliseconds, N23 latency of 25.58 ± 2.02 milliseconds, and peak-to-peak amplitude of 15.39 ± 3.45 µV. One-sample t -test revealed statistically significant longer latencies and smaller amplitude of the toddlers' cVEMPs relative to the normative data for adults. Conclusions The difficulty of cVEMPs testing in toddlers can be overcome by sedating them and attaining a position that contracts the SCM muscle. However, the toddlers' recordings revealed delayed latencies and smaller amplitudes than those of adults.

“…In contrast to this study, some investigators demonstrate different values as in Akin et al [32] , Cheng, Huang, and Young [33] , Said [2] , and El-Danasoury, El Sirafy et, al. [34] . They explained the earlier recording in children might be due to changes in dimensions of the head and neck in younger children which make the recording electrodes closer to the generator sites resulting in shorter latencies.…”

Background: Combined hearing and vestibular loss in children pose potentially significant problems. Children and infants with vestibular problems are faced with motor problems that could limit their normal development. Objectives: the aim of the study is to assess the relationship between the vestibular disorders and the delayed motor development in hearing impaired children as well as to assess the integrity of the vestibular system through clinical testing and radiological imaging in those children with delayed motor development. Methods: Thirty hearing impaired children with history of delayed motor milestones, and a control group of 10 hearing impaired children with normal motor development were included with variable degree of hearing loss. Each child was subjected to careful history taking, general examination, otoscopic examination, motor and balance questionnaires were answered by the parents or caregivers, audiological evaluation either through conditioned play audiometry or conventional audiometry, speech audiometry and Immittancemetry. Vestibular evaluation through cVEMP and caloric tests and finally the radiological studies through CT and MRI of the petrous bone. Results: There were variable degrees of hearing loss among both groups. In the control group (10 HI children, 20 ears), 18 ears (90%) had VEMP response, while two ears (10%) had absent VEMP, while in the study group (30 HI children, 60 ears), 48 ears (80%) had VEMP response, while 12 ears (20%) had absent VEMP. All children in the control group had normal caloric response, while in the study group, 23 children (77%) had normal response, and seven children (23%) had abnormal caloric response, 4 children had bilateral weakness and 3 had unilateral weakness. CT and MRI study of petrous bone was done for the control group and revealed normal radiology, while in the study group, 21 children had normal imaging (70%) and the last 9 children (30%) had abnormal findings, the most common abnormalities was enlarged vestibular aqueduct (13%), followed by common cavity (7%). Conclusion: Children with hearing loss, irrespective of the degree of hearing loss, the vestibular system should be screened, assessed as it may be responsible for co-morbidities in fine and gross motor difficulties. Early intervention and effective therapy will be the proper way to get good outcome.
