“…Therefore, one can conclude that all the procedures used in the present study including the SVINT were safe and had no adverse effect on the children or their devices. Similar safety concerns were addressed and dissipated in the previous literature [ 14 ].…”

“…A negative SVINT result was observed in the remaining 117 children (97.5%) according to the criteria defined in Table 2 . Among these children with negative SVINT, 94 children did not have any nystagmus, and 23 children had nonclinically significant nystagmus (For more details, please review the full data published in SVINT as a screening tool in children [ 14 ]). In children, SVINT can detect unilateral vestibular deficit in a very high frequency with a sensitivity of 86% and a specificity of 96%.…”

Correlation of SVINT and Sensory Organization Test in Children with Hearing Loss

Objective: The skull vibration-induced-nystagmus test (SVINT) is a noninvasive and effective screening tool for the function of the otolith and canal structures in children. It can instantaneously assess vestibular asymmetry. This study aimed to analyze the SVINT results of healthy children vs. children with hearing loss (HL) and to correlate it with sensory organization test (SOT) results as a functional balance evaluation tool. Design: This case-controlled study compared the results of SVINT to the results of the SOT of the computerized dynamic posturography (CDP) in a control group of 120 healthy normal-hearing children (i.e., NH group) vs. hearing loss (HL) group of 60 children, including 30 children with hearing aids (HAs) and 30 children with a unilateral cochlear implant (CI). The SVINT results were compared to the caloric test (CaT) and video head impulse test (vHIT) and associated with SOT scores. Results: Thirty-one children in the HL group had normal SVINT and normal SOT results. A total of 21 children in the HL group had SVINT-negative and abnormal results in the SOT (possibly due to bilateral vestibular loss (BVL)). Eight children in the HL group had positive SVINT and abnormal SOT results. However, none of the children had only positive SVINT with normal SOT findings. Moreover, 52% of children had a normal result on both the SOT and CaT, whereas 27% had abnormal results on both tests (17% bilateral weakness and 10% unilateral), and 22% had the only result of the SOT suggesting a functional abnormality. Similarly, when associating the result to vHIT, 51% had normal results on both tests, and 25% had abnormal results (13% bilateral and 12% unilateral weakness). Conclusion: SVINT findings can be correlated with SOT findings in the case of the unilateral vestibular lesion (UVL), which adds a diagnostic value in these pediatric cases but may differ in the case of the bilateral vestibular lesion (BVL). However, SVINT findings need to be cautiously interpreted in light of other test findings such as the SOT, CaT, and vHIT.

This review reports on recent advances in understanding nystagmus and other involuntary eye movements. Advances in quantitative evaluations of eye movements using oculography, computational model simulations, genetics, and imaging technologies have markedly improved our understanding of the pathophysiology of involuntary eye movements, as well as their diagnosis and management. Patient-initiated capture of eye movements, especially when paroxysmal, and the online transfer of these data to clinicians would further enhance the ability to diagnose involuntary eye movements.

“…Responses were more frequently observed on the vertex than in patients with SUVL or TUVL (where they were mainly obtained on the mastoid process) at 100 Hz [ 1 ]. Sinno et al highlighted the importance of the test as a screening tool in children with hearing loss (amplified with hearing aid or cochlear implant) [ 43 ]. In 2021, Dumas et al found that SVINT results in a human model of horizontal SCC plugging used for disabling an MD patient correlated with vestibular tests exploring horizontal canal function but not with cVEMP [ 44 ].…”

This review enumerates most of the studies on the Skull Vibration-Induced Nystagmus Test (SVINT) in the past 50 years from different research groups around the world. It is an attempt to demonstrate the evolution of this test and its increased interest around the globe. It explores clinical studies and animal studies, both permitting a better understanding of the importance of SVINT and its pathophysiology.
