“…In agreement with our study, Mallinson et al [30] also found that cVEMP and oVEMP abnormalities do not correlate with CDP findings. CDP measures dynamic sway and VEMPs are related to activities involving head movement and are not a measure of body sway [30].…”

Introduction: In migraine, there is no anatomical correlate of vertigo and no structural abnormality is evident in conventional imaging. Cervical vestibular-evoked myogenic potential (cVEMP) is an uncrossed inhibitory vestibulo-spinal reflex (VSR), while ocular VEMP (oVEMP) represents a crossed excitatory vestibulo-ocular reflex (VOR).Objective: This study aims at functional evaluation of the findings of cVEMP and oVEMP in migraine patients. Material and methods:This was a cross-sectional case-control study that included 20 migraine patients as the case group and 30 healthy adult subjects as a control group. All participants were subjected to history taking, otological examination, basic audiological evaluation, bedside examination of the dizzy patient, cVEMP, oVEMP, and posturography tests.Results: 35% of migraine patients showed delayed cVEMP latency and 40% showed abnormal oVEMP in the form of statistically significant delayed right oVEMP P1 (p = 0.050) and left oVEMP N1 latency (p = 0.038) compared with controls. cVEMP parameters were not correlated to posturography results. The majority of migraine patients (70%) had normal equilibrium pattern and normal sensory analyses ratios (65%). Only 30% had vestibular dysfunction.Conclusions: VSR and VOR are affected in migraine patients. We recommend the use of cVEMP and oVEMP in migraine patients for functional assessment of brainstem pathways.

“…a normal BMI had a mean vestibular ratio score of 51.14 compared with 45.64 in overweight children and 46.99 in obese children. A similar observation was noted in children aged 9 to 11 years; a mean vestibular ratio score of53.71 was found in children with a normal BMI compared with 34.12 in obese children. No significant differences in mean visual preference ratio scores were found across age groups (p ¼ 0.403) or gender (p ¼ 0.661).…”

“…Although the relationship between CDP and VEMP is not clear, the authors acknowledge that the inclusion of VEMP testing would have provided further evidence of vestibular status. 53,54 If undetected vertical canal or otolithic disorders were present in children, this could potentially have affected the findings of the study. Finally, little information is available in the literature about postural control changes in individuals transitioning to adulthood (i.e., ages [17][18][19][20].…”

“…This could have been performed by assessing all subjects by video head impulse test and VEMPs. Mallinson et al 53 showed that CDP assessment does not correlate with oVEMP and cVEMP results. However, Jacobson et al 54 showed that patients with abnormal unilateral saccular or inferior vestibular nerve function (i.e., abnormal cVEMP) demonstrated significantly impaired postural control.…”

Changes in the Sensory Weighting Strategies in Balance Control Throughout Maturation in Children

et al. 2020

Background The central nervous system integrates information from different sensory inputs (vestibular, visual, and somatosensory) to maintain balance. However, strategies for weighing sensory information change as maturation occurs. Purpose The purpose of this study was to: (1) evaluate postural control development in a large sample of healthy children aged 5 to 17 years old, (2) analyze changes in sensory weighting strategies as maturation occurs, and (3) determine the extent to which anthropometric characteristics (height, weight, body mass index [BMI]) influence postural control. Sample Size This study recruited 120 healthy children, equally distributed in gender and number, into four age groups (5–8 years, 9–11 years, 12–14 years, and 15–17 years) and compared them to a control group of 20 healthy adults (aged 20–25 years). Research Design The sensory organization test (SOT) was used to assess overall balance and the use of specific sensory inputs to maintain postural control. All children underwent the six SOT conditions: (1) eyes open, surround and platform stable, (2) eyes closed, surround and platform stable, (3) eyes open, sway-referenced surround, platform stable, (4) eyes open, sway-referenced platform, (5) eyes closed, sway-referenced platform, and (6) eyes open, sway-referenced surround and platform. Data Analysis Condition-specific equilibrium scores (ES), composite equilibrium scores (CES), and sensory analysis ratios were analyzed to determine whether the performance was related to age, gender, or specific anthropometric characteristics (height, weight, and BMI). Results Data showed a significant age-associated improvement in ES for all 6 conditions (p < 0.05) and in CES (p = 0.001). For both genders, (1) somatosensory function was adult-like by age 5 to 8 years, (2) visual function peaked around age 12 years, and (3) vestibular function reached maturity by age 15 to 17 years (p < 0.05). A moderate positive correlation (r(140) = 0.684, p = 0.01; two-tailed) between height and CES was found and a weak positive correlation (r(140) = 0.198, p = 0.01) between height and somatosensory ratio was noted. Lower vestibular ratio scores were observed in children who had a higher BMI (p = 0.001). Conclusion The efficient use of individual sensory system input to maintain balance does not occur at the same age. Age and gender affect the changes in sensory weighting strategies, while height and BMI influence postural control in children. These factors need to be accounted for in child assessment.

“…The accurate determination of the location of lesions is useful for studying the pathophysiology of vestibular diseases (18). The analysis of 180 patients with vestibular complaints examined with a full battery of vestibular assessments including VEMP testing and comput-erized dynamic posturography establishes the same rate of VEMP abnormalities in patients with normal and those with abnormal computerized dynamic posturography (19). However, these modalities measure different things and are all important in the diagnostic armamentarium.…”

In the present concise review of the recent literature, the new interdisciplinary paradigm of audiovestibular medicine as a challenge to theory and clinical practice is presented. Most common symptoms include dizziness, vertigo, tinnitus, nystagmus, and hearing loss. Several conventional and newly-introduced methods for the precise diagnosis of audiovestibular disorders and their applications are illustrated. The need for further interdisciplinary research by national and international teams of otologists, neurootologists and specialists of verstibulogy is emphasized.
