“…Patients with bilateral vestibular loss score similarly to control groups (Tabak et al, 1997 ; Guerraz et al, 2001 ), although a closer examination of their SVV reveals greater inter-trial variability (Funabashi et al, 2012 ). Much of the research to date has focused on visual vertical perception in adults, yet Brodsky et al ( 2016 ) have recently demonstrated that the evaluation of SVV in pediatric patients is, in fact, feasible. Furthermore, the use of a smartphone application increases participant compliance without sacrificing the sensitivity of the test to peripheral vestibular loss (Brodsky et al, 2015 ).…”

Vestibular end organ impairment is highly prevalent in children who have sensorineural hearing loss (SNHL) rehabilitated with cochlear implants (CIs). As a result, spatial perception is likely to be impacted in this population. Of particular interest is the perception of visual vertical because it reflects a perceptual tilt in the roll axis and is sensitive to an imbalance in otolith function. The objectives of the present study were thus to identify abnormalities in perception of the vertical plane in children with SNHL and determine whether such abnormalities could be resolved with stimulation from the CI. Participants included 53 children (15.2 ± 4.0 years of age) with SNHL and vestibular loss, confirmed with vestibular evoked myogenic potential (VEMP) testing. Testing protocol was validated in a sample of nine young adults with normal hearing (28.8 ± 7.7 years). Perception of visual vertical was assessed using the static Subjective Visual Vertical (SVV) test performed with and without stimulation in the participants with cochleovestibular loss. Trains of electrical pulses were delivered by an electrode in the left and/or right ear. Asymmetric spatial orientation deficits were found in nearly half of the participants with CIs (24/53 [45%]). The abnormal perception in this cohort was exacerbated by visual tilts in the direction of their deficit. Electric pulse trains delivered using the CI shifted this abnormal perception towards center (i.e., normal; p = 0.007). Importantly, this benefit was realized regardless of which ear was stimulated. These results suggest a role for CI stimulation beyond the auditory system, in particular, for improving vestibular/balance function.

“…43,46 All of these tests have been included in studies involving child participants, but not in children with CP. 43,44,[46][47][48] The perception of upright (i.e., true vertical and horizontal) is thought to be mediated by the utricle, central utricular pathways, and vestibular cortex. 49 This function is measured using the test of SVV.…”

“…50 Recent studies have determined normative values and age/gender effects of SVV for children. 47,48 Brodsky et al 48 tested 33 children aged 7 to 18 years, n ¼ 12 typically developing and n ¼ 21 with dizziness. Typically developing children (mean age ¼ 13.9, SD ¼ 2.8) had a mean SVV of 0.7 (SD ¼ 0.5) and a score of more than 2 degrees identified children with peripheral vestibular impairment (100% sensitivity and 75% specificity).…”

“…Typically developing children (mean age ¼ 13.9, SD ¼ 2.8) had a mean SVV of 0.7 (SD ¼ 0.5) and a score of more than 2 degrees identified children with peripheral vestibular impairment (100% sensitivity and 75% specificity). 48 Toupet et al 47 reported SVV tilt and results of vestibular diagnostic tests in 492 children aged 4 to 19 years with various vestibular disorders (n ¼ 73 with normal vestibular function). Although the mean SVV tilt was within accepted ranges for adults, À0.02 AE 1.64, all children perceived vertical as tilted toward the side of initial presentation, which was noted significantly more in children aged 4 to 7 years than in children 15 to 17 years.…”

“…Christy et al 50 tested SVV in children aged 6 to 12 (mean age ¼ 9.8, SD ¼ 1.8) with severe to profound sensorineural hearing loss. The children without vestibular hypofunction as measured with rotary chair and cVEMP (n ¼ 11) had a mean SVV of 2.15 (SD ¼ 1.5), which would have been considered abnormal if using the cutoff score suggested by Brodsky et al 48 More studies are needed to determine reliabi-lity, normative values, cutoff scores, and the age at which children of all ages are able to reliably complete the test. No study has examined SVV in children with CP.…”

Vestibular and Oculomotor Function in Children with Cerebral Palsy: A Scoping Review

2018

View full text Add to dashboard Cite

Cerebral palsy (CP) is a nonprogressive permanent brain injury that causes an impairment of movement and posture. This scoping review aimed to answer the following questions: (1) "What is the status of oculomotor function in children with CP?" (2) "What is the status of vestibular function (i.e., gaze stability, perception of vertical, vestibular-related balance abilities) in children with CP?" Using Arksey's and O'Malley's five-stage framework, we searched six online databases for relevant articles. The inclusion criteria were: (1) participants of the studies included individuals with CP; (2) a primary outcome in the studies was measurement of oculomotor, vestibular, and/or balance; (3) studies were published within the past 20 years; and (4) the participants in the studies were between 0 and 21 years of age. Twenty-one articles were found that described impairments in oculomotor function ( = 9), vestibular function ( = 1), and oculomotor and vestibular integration ( = 11) in children with CP. The evidence suggests that children with CP may have altered saccadic and smooth pursuit eye movements, abnormal saccular function, poor eye-hand coordination, and abnormal use of vestibular information for balance. Future studies should explore peripheral and central vestibular function using reliable and valid methods for this population. This scoping review demonstrated a paucity of rigorous and objective research to describe the status of oculomotor and vestibular function in children with CP. However, preliminary studies suggest that more research is warranted.

Different studies have tried to establish a relationship between dyslexia and the vestibular system function. Subjective Visual Vertical/Horizontal (SVV and SVH) and Video Head Impulse Test (VHIT) are useful for studying the vestibular system and can be easily performed in children. Our aim was to evaluate the vestibular function in dyslexic children by SVV/SVH and VHIT. We enrolled 18 dyslexic children (10M/8F; mean age 10.7 ± 2.3 years; range 7–14 years) and 18 age‐matched children with typical development of learning abilities. All children performed VHIT, SVV and SVH. We found normal gain and symmetry of vestibulo‐ocular‐reflex both in dyslexic and typically developing children. Fifteen out of 18 dyslexic children (83.3%) showed a difference of at least one amongst SVV or SVH. The mean value of SVV was 2.3° and the mean value of SVH was 2.6°. Statistical analysis showed a significant difference between typically developing and dyslexic children for both SVV and SVH. We confirm a relationship between dyslexia and the alteration of SVV and SVH. Our results could be related to the pathogenetic hypothesis of a visual processing impairment related to a dysfunction of the magnocellular pathway or to a general deficit related to a multimodal cortical network.
