Speech perception in patients submitted to cochlear reimplantation.

Purpose: To analyze the performance of auditory speech perception (PF) after cochlear implant (CI) replacement surgery and associations with age, times of use of the first CI, deprivation, recovery and use of the second device.

Methods: The retrospective study analyzed the medical records of 68 participants reimplanted from 1990 to 2016, and evaluated with PF performance tests, considering as a reference, the greater auditory capacity identified during the use of the first CI. Also analyzed were: Etiology of hearing loss; the reasons for the reimplantation; device brands; age range; sex; affected ear; age at first implant; time of use of the first CI, deprivation, recovery and use of the second device.

Analysis of aided thresholds in children who have undergone cochlear reimplantation: a ten-year follow-up.

Purpose: To characterize hearing thresholds at frequencies of 500, 1000, 2000 and 4000 Hz in children undergoing reimplantation with a follow-up of at least 10 years.

Methods: Retrospective review of medical records of children who underwent reimplantation surgery for at least 10 years. The auditory thresholds obtained in free-field pure tone audiometry with the cochlear implant were evaluated at frequencies of 500, 1000, 2000 and 4000 Hz at four different times: 1 (before failure), 2 (activation), 3 (five years after reimplantation) and 4 (ten years after reimplantation, regardless of the time of use of the 2nd CI) in patients with a follow-up of at least 10 years.

Effects of Sequential Bilateral Cochlear Implantation in Children: Evidence from Speech-Evoked Cortical Potentials and Tests of Speech Perception.

Introduction: Benefits of bilateral cochlear implants (CI) may be compromised by delays to implantation of either ear. This study aimed to evaluate the effects of sequential bilateral CI use in children who received their first CI at young ages, using a clinical set-up.

Methods: One-channel cortical auditory evoked potentials and speech perception in quiet and noise were evoked at repeated times (0, 3, 6, 12 months of bilateral CI use) by unilateral and bilateral stimulation in 28 children with early-onset deafness.

Auditory sentence comprehension in children with cochlear implants after simple visual discrimination training with specific auditory-visual consequences.

The present study evaluated the effects of simple discrimination training with specific consequences on auditory comprehension in children with cochlear implants (CIs). Demonstration of auditory comprehension was based on derived conditional relations and the formation of equivalence relations. Participants learned two sets of three simple visual discriminations in which the positive stimulus (S) was a written pseudo-sentence (C1, C2, or C3) or a compound abstract picture (D1, D2, or D3), displayed in the correct orientation.

Glendonald Auditory Screening Procedure (GASP): clinical markers of the development of auditory recognition and comprehension abilities in children using cochlear implants.

Purpose: To verify the influence of the age of implantation in the development of closed-set auditory recognition and auditory comprehension abilities in children using unilateral cochlear implants (CI), comparing distinct groups and determining clinical markers.

Methods: Participants were 180 children operated and activated until 36 months of age and who used a CI for at least 60 months. Abilities of auditory recognition in closed-set and auditory comprehension were analyzed through the GASP Tests 5 and 6.

Multiple exemplar instruction and integration of listening and speaking behaviors with substantive-adjective syntactic units in children with ANSD and CI.

Purpose: To verify the effect of the multiple exemplar instruction at the acquisition and integration of listening and speaking behaviors, with substantives and substantive-adjective combinations, in children with Auditory Neuropathy Spectrum Disorder (ANSD) and cochlear implant (CI).

Methods: Participants were two children with ANSD that were users of CI. We adopted dictated stimulus and pictures that corresponded to words (substantive) and substantive-adjective syntactic units.

Improving oral sentence production in children with cochlear implants: effects of equivalence-based instruction and matrix training.

ᅟ: Children who use cochlear implants (CI) and who are readers usually produce more accurate speech in response to text than to pictures. Equivalence-based instruction (EBI) can be a route to establish functional interdependence between these verbal operants. The present study investigated whether children with CI who read would improve speech accuracy when tacting pictures of scenes after EBI that included dictated sentences, pictures of scenes, and printed sentences.

Outcomes of cochlear implanted children with cerebral palsy: A holistic approach.

Objective: Analyze the progress of hearing and language in a group of children with cerebral palsy (CP) who have received cochlear implants (CI) and compare their progress in the clinical and functional domains.

Methods: This is a prospective transdisciplinary study developed within a tertiary referral center, with a group of nine cochlear-implanted children with CP, two- to seven-year-old. The assessments undertaken included audiological, language, and communication assessments complemented by the assessment of functional abilities and the level of independence as evaluated by the Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Classification System (GMFCS).

Global developmental abilities of cochlear implanted children with spastic cerebral palsy: two experimental groups.

Purpose: To analyze gross motor, fine motor-adaptive, language, social function performance, and communicative behaviors among cochlear-implanted children with spastic cerebral palsy (CP) and children with CP without hearing loss (HL) and to compare them with children with normal development.

Methods: Prospective cross-sectional study involving 12 children with mean age of 63 months, distributed into two experimental groups: G1-4 children with CP and cochlear implant (CI) users and G2-4 children with CP without HL. A third group (G3) was the control group with four typically developing children.
