Benefits of Parent Training in the Rehabilitation of Deaf or Hard of Hearing Children of Hearing Parents: A Systematic Review

Coalition for Global Hearing Health Hearing Care Pathways Working Group: Guidelines for Clinical Guidance for Readiness and Development of Evidence-Based Early Hearing Detection and Intervention Programs

Editor's Note: The following article discusses the timely topic Clinical Guidance in the areas of Evidence-Based Early Hearing Detection and Intervention Programs. This article aims to discuss areas of services needed, guidance to countries/organizations attempting to initiate early hearing detection and intervention systems. Expert consensus and systematic/scoping reviews were combined to produce recommendations for evidence-based clinical practice. In Ear and Hearing, our long-term goal for the Point of View article is to stimulate the field's interest in and to enhance the appreciation of the author's area of expertise. Hearing is an important sense for children to develop cognitive, speech, language, and psychosocial skills. The goal of universal newborn hearing screening is to enable the detection of hearing loss in infants so that timely health and educational/therapeutic intervention can be provided as early as possible to improve outcomes. While many countries have implemented universal newborn hearing screening programs, many others are yet to start. As hearing screening is only the first step to identify children with hearing loss, many follow-up services are needed to help them thrive. However, not all of these services are universally available, even in high-income countries. The purposes of this article are (1) to discuss the areas of services needed in an integrated care system to support children with hearing loss and their families; (2) to provide guidance to countries/organizations attempting to initiate early hearing detection and intervention systems with the goal of meeting measurable benchmarks to assure quality; and (3) to help established programs expand and improve their services to support children with hearing loss to develop their full potential. Multiple databases were interrogated including PubMed, Medline (OVIDSP), Cochrane library, Google Scholar, Web of Science and One Search, ERIC, PsychInfo. Expert consensus and systematic/scoping reviews were combined to produce recommendations for evidence-based clinical practice. Eight essential areas were identified to be central to the integrated care: (1) hearing screening, (2) audiologic diagnosis and management, (3) amplification, (4) medical evaluation and management, (5) early intervention services, (6) family-to-family support, (7) D/deaf/hard of hearing leadership, and (8) data management. Checklists are provided to support the assessment of a country/organization's readiness and development in each area as well as to suggest alternative strategies for situations with limited resources. A three-tiered system (i.e., Basic, Intermediate, and Advanced) is proposed to help countries/organizations at all resource levels assess their readiness to provide the needed services and to improve their integrated care system. Future directions and policy implications are also discussed.

Videofeedback-guided teleintervention for the family of a child with a cochlear implant: a case study

Interventions for parental training for families of hard of hearing children, including cochlear implant users, are identified as optimizing their developmental outcomes. In this single-case intervention study, we aim to describe the use of videofeedback in a remote environment, as well as to identify its effectiveness, based on the analysis of mother-child interaction, both for the mother's communicative behaviors and for the behaviors of the mother, receptive and expressive language of the child. Pre- and post-intervention measurements were performed, based on video analysis of the mother's interaction with the child, by blind judges, as well as through the application of assessment instruments for the child and the mother. There were 13 sessions, 3 of which were for evaluation before and after the intervention and 10 of teleconsultation sessions in which the videofeedback tool was used with the mother. Data were analyzed descriptively and inferentially, using the JT method, which determined the Reliable Change Index (BMI) and Clinical Significance. There was reliable positive change in the child's receptive and expressive language, as well as reliable positive change and clinically significant change in mother-child interaction after the 10 sessions of remote videofeedback intervention. Based on the reliable changes observed in this study, we present this model (televideofeedback) as a potential to optimize resources and efforts for therapeutic success in children's auditory rehabilitation, which should be studied in research with a rigorous method, for the broad recommendation of its use.

Long-term speech perception and morphosyntactic outcomes in adolescents and young adults implanted in childhood

BACKGROUND

Long-term assessments of children with cochlear implants (CI) are important inputs to help guide families and professionals in therapeutic and counselling processes. Based on these premises, the primary aim of the present study was to assess the long-term speech and language outcomes in a sample of prelingually deaf or hard of hearing (DHH) adolescents and young adults with unilateral or bilateral implantation in childhood. The secondary aim was to investigate the correlations of age at implantation with long-term speech and language outcomes.

MATERIALS AND METHODS

Retrospective observational study on 54 long-term CI users, 33 unilateral and 21 bilateral (mean age at CI surgery 38.1 ± 24.6 months; mean age at last follow-up assessment 19.1 ± 4.3 years of age and mean follow-up time 16 ± 3.7 years). Means and standards were used to describe speech perception (in quiet, in fixed noise and in adaptive noise using It-Matrix) and morphosyntactic comprehension (TROG-2) outcomes. A univariate analysis was used to evaluate outcome differences between unilateral and bilateral patients. Bivariate analysis was performed to investigate the relationships between age at CI, audiological variables, and language outcomes. Finally, multivariate analysis was performed to quantify the relationship between It-Matrix, sentence recognition in quiet and at SNR+10 and TROG-2.

RESULTS

The participants showed good speech recognition performance in quiet (94% for words and 89% for sentences) whilst their speech-in-noise scores decreased significantly. For the It-Matrix, only 9.2% of the participants showed scores within the normative range. This value was 60% for TROG-2 performance. For both auditory and language skills, group differences for unilateral versus bilateral CI users were not statistically significant (p > 0.05). Bivariate analysis showed that age at CI correlated significantly with overall results at TROG-2 (r = -0.6; p < 0.001) and with It-Matrix (r = 0.5; p < 0.001). TROG-2 was negatively correlated with results for It-Matrix (r = -0.5; p < 0.001). In the multivariate analysis with It-Matrix as a dependent variable, the model explained 63% of the variance, of which 60% was related to sentence recognition and 3% to morphosyntax.

CONCLUSIONS

These data contribute to the definition of average long-term outcomes expected in subjects implanted during childhood whilst increasing our knowledge of the effects of variables such as age at CI and morphosyntactic comprehension on speech perception. Although the majority of this prelingually DHH cohort did not achieve scores within a normative range, remarkably better It-Matrix scores were observed when compared to those from postlingually deafened adult CI users.

Symbolic and deictic gestures as a tool to promote parent-child communication in the context of hearing loss: A systematic review

BACKGROUND

Language and communication outcomes in children with congenital sensorineural hearing loss (cSNHL) are highly variable, and some of this variance can be attributed to the quantity and quality of language input. In this paper, we build from the evidence that human language is inherently multimodal and positive scaffolding of children's linguistic, cognitive, and social-relational development can be supported by Parent Centered Early Interventions (PCEI), to suggest that the use of gestures in these interventions could be a beneficial approach, yet scarcely explored.

AIMS AND METHODS

This systematic review aimed to examine the literature on PCEI focused on gestures (symbolic and deictic) used to enhance the caregiver-child relationship and infant's language development, in both typically and atypically developing populations. The systematic review was conducted following the PRISMA guidelines for systematic reviews and meta-analyses. From 246 identified studies, 8 met PICO inclusion criteria and were eligible for inclusion. Two reviewers screened papers before completing data extraction and risk of bias assessment using the RoB2 Cochrane scale.

RESULTS

Included studies measured the effect of implementing symbolic or deictic gestures in daily communication on the relational aspects of mother/parent-child interaction or on language skills in infants. The studies indicate that gesture-oriented PCEI may benefit deprived populations such as atypically developing children, children from low-income families, and children who, for individual reasons, lag behind their peers in communication.

CONCLUSIONS

Although gesture-oriented PCEI appear to be beneficial in the early intervention for atypically developing populations, this approach has been so far scarcely explored directly in the context of hearing loss. Yet, symbolic gestures being a natural part of early vocabulary acquisition that emerges spontaneously regardless of hearing status, this approach could represent a promising line of intervention in infants with cSNHL, especially those with a worse head start.
