“…Regarding the general characteristics of the articles included in the systematic review, 6 articles carried out their research using a control group compared to those implanted ( 23 , 34 , 41 , 42 , 49 ), while the remaining 32 studies compared the results of their patients before and after cochlear implant ( Supplementary Table 1 ).…”

“…Among all the 38 articles, after judgment based on the risk of bias analysis (JBI), analytic cross-sectional studies, and according to each study type, 25 studies showed a low risk of bias ( 9 , 14 , 16 , 24 , 27 , 31 , 33 , 35 , 36 , 38 , 39 , 42 – 44 , 46 , 48 – 55 ), 10 articles ( 15 , 23 , 25 , 26 , 28 – 30 , 32 , 34 , 47 ) showed a moderate risk of bias, and 3 articles ( 21 , 40 , 45 ) had a high risk of bias.…”

“…Due to the different opinions and studies, authors disagree with their findings. Between authors who describe that CI can improve body balance ( 8 , 10 – 12 ), those who believe that CI negatively interferes with vestibular function ( 9 , 13 – 19 ), and authors who maintain that CI has no effect in this regard ( 16 , 20 – 23 ), there are many different studies and evaluation methodologies.…”

IssueThe findings in literature indicate inconsistency in the complications caused by the implant of electrodes in the cochlea; vestibular alterations and balance disorders are mentioned as the most likely.PurposeTo evaluate, in literature, through the results of multiple vestibular function tests, the effects of cochlear implant surgery on postural stability in adult patients and to analyze.HypothesisFrom the PICO strategy, where the Population focuses on adults, Intervention is cochlear implant surgery, Comparisons are between implanted patients, and Outcomes are the results of the assessment of cochlear function, the research question was formulated: Are there deficits in vestibular function in adults undergoing cochlear implant placement?MethodSystematic review based on cohort, case–control, and cross-sectional observational studies. Information sources: Databases between 1980 and 2021, namely, PubMed, Cinahl, Web Of Science, Cochrane, and Scopus. Search strategy using Mesh terms: “Adult,” “Cochlear Implant,” “Postural Balance,” “Posturography,” “Cochlear Implant,” “Dizziness,” “Vertigo,” “Vestibular Functional Tests,”and “Caloric Tests.” Populational inclusion criteria: studies with adult patients; intervention: cochlear implant placement surgery; comparison: analysis of a vestibular function with vestibular test results and pre- and postoperative symptoms; outcome: studies with at least one of the vestibular function tests, such as computerized vectoelectronystagmography (VENG), vestibular-evoked myogenic potentials (VEMPs), caloric test, video head impulse test (VHIT), head impulse test (HIT), videonystagmography, (VNG) and static and dynamic posturography. Exclusion criteria: studies without records of pre- and postoperative data collection and studies with populations under 18 years of age. Screening based on the reading of abstracts and titles was performed independently by two reviewers. In the end, with the intermediation of a third reviewer, manuscripts were included. Risk of bias analysis, performed by two other authors, occurred using the JBI “Critical Appraisal Checklist.”ResultsOf the 757 studies, 38 articles met the inclusion criteria. VEMP was the most commonly used test by the studies (44.7%), followed by the caloric test (36.8%) and vHIT (23.6%). Most studies performed more than one test to assess vestibular function.ConclusionAmong all vestibular tests investigated, the deleterious effects on vestibular function after cochlear implant surgery were detected with statistical significance (P < 0.05) using VEMP and caloric test. Comparing abnormal and normal results after implant surgery, the vestibular apparatus was evaluated as having abnormal results after cochlear implant surgery only in the VEMP test. The other tests analyzed maintained a percentage mostly considered normal results.Systematic review registrationidentifier: CRD42020198872.

“…Frente a este hallazgo, no fue posible encontrar literatura en niños, sin embargo, (Bujang, 2013) refieren que en adultos usuarios de Implante Coclear frente a controles sanos, no presentaron diferencias significativas en estas variables de Límites de Estabilidad (LOS), lo que era atribuible a una respuesta de adaptación vestibular frente a la novedad del implante por parte del grupo en estudio, lo que estaría en oposición a lo reportado con anterioridad que podría ser explicado por la diferencia de edad de los sujetos y por ende, diferentes habilidades adquiridas.…”

La posturografía permite evaluar la integración de los tres sistemas sensoriales que intervienen en el control postural y del equilibrio: el vestibular, el visual y el somatosensorial (Ronda, Galvañ, Monerris y Ballester, 2002). La presente investigación busca describir y analizar los resultados de la posturografía en niños entre seis y once años con pérdida auditiva quienes no han compensado su edad auditiva con respecto a su edad cronológica. Fueron evaluados dos grupos: el grupo control conformado por 32 niños con sensibilidad auditiva periférica normal y el grupo de estudio, conformado por 16 niños con pérdida auditiva, quienes usan amplificación auditiva y asisten a la Fundación CINDA para terapia auditiva con el fin de cerrar el GAP existente entre su edad cronológica y su edad auditiva. En la evaluación audiológica se aplicó anamnesis, revisión de historia clínica, audiometría tonal para la verificación de la sensibilidad auditiva periférica y posturografía, con un equipo de la marca NeuroCom, realizándose las siguientes pruebas: Integración sensorial en balance-modificado (CTSIB), límites de estabilidad (LOS) y distribución de peso (WHT). En los resultados se encontraron diferencias estadísticamente significativas entre los dos grupos de estudio para las tres pruebas en distintas variables. Como conclusión se pudo determinar que existen diferencias estadísticamente significativas entre el grupo control y el grupo de estudio. La intervención con terapia ocupacional influenció positivamente los resultados en la posturografía, sobre todo en el grupo de 10 a 11 años. Se observaron diferencias sucesivas en los tres grupos de edad, indicando un componente de neuromaduración.

Many disorders, such as nervous system disorders, can affect orientation of the body segments in 3D space negatively. Patients with these disorders often show body segments instability during stance tasks. Nowadays, 3-axis gyroscopes are about to be used to measure postural stability. The main objective of the paper is to describe a method which would be suitable for quantifying postural stability and 3D movement as a whole using a cheap 3-axis gyroscope. New method based on the volume of a 3D convex hull (CH) obtained by plotting pitch, roll and yaw angles versus each other was proposed for quantitative evaluation of 3D trunk sway. The sway was measured while patients with degenerative cerebellar disorder (Pts) and eleven healthy subjects (HSs) performed quiet stance on a firm surface (FiS) and foam surface (FoS) with open eyes (OE) and closed eyes (CE). The CH was used to identify differences in balance control, and there were significant differences found between the two groups. The median (Mdn) of the volume of Pts with OE on FiS is four times larger than the Mdn of the volume of HS with OE on FiS. The Mdn of the volume of Pts with CE on FoS is 80 times larger than the Mdn of the volume of HS with CE on FoS. It was therefore found that the volume of CH is suitable for quantifying postural sway and identifying differences in balance control.
