Interconnected Pathways: Postural Stability and Vocabulary Skills in Preschool-Aged Children.

Previous research has highlighted an interplay between postural abilities and linguistic skills during infancy. However, this relationship could undergo further radical transformations in other periods of development. This current study explored a plausible network of relationships among postural abilities and vocabulary skills in a substantial cohort (N = 222) of preschoolers aged between 2 and 5 years-a developmental phase critical for refining both language and motor competencies. Here, postural stability was measured in terms of balance duration and accuracy, alongside an assessment of comprehension and expressive vocabulary skills. Employing a diverse set of techniques, i.e., data and missing data visualization and multilevel regression analysis, task complexity and age emerged as crucial factors explaining our data. In addition, network analysis indicates that language production plays a central role within postural and language interdomain networks. The resulting discussion focuses on the useful implications of this study for the assessment of typical preschool development, which would benefit from tailored methodological inspections guided by developmental theories that are framed in inter-domain approaches.

Benefits of bone conduction hearing aid in children with unilateral aural atresia.

Objective: To assess the hearing benefit with a unilateral bone conduction hearing aid in a cohort of children with unilateral aural atresia. Methods: Cross-sectional case series pilot study involving 7 children (median age: 10 years, range 6-11). All patients underwent pure-tone, speech, aided sound field and aided speech audiometry and Simplified Italian Matrix Test (SIMT) with and without bone conduction hearing aid (Baha 5® CochlearTM). Cognitive abilities were assessed in 5 patients. Results: The mean air conduction pure-tone average (PTA) of the atretic ear was 63.2 ± 6.9 dB, while the bone conduction PTA was 12.6 ± 4.7 dB. Speech discrimination score of the atretic ear was 88.6 ± 3.8 dB, while with the hearing aid it was 52.8 ± 1.9 dB. In the contralateral ear, there was no significant air-bone gap, and PTAs for air and bone conduction thresholds were within normal range (PTA ≤ 25 dB). The mean aided air conduction hearing threshold was 26.2 ± 7.97. Mean speech recognition threshold without the hearing aid was -5.1 ± 1.9 dB, and -6.0 ± 1.7 dB with the hearing aid tested with the SIMT. The mean score of the cognitive test was 46.8 ± 42.8. Conclusions: These preliminary findings should encourage clinicians in proposing a unilateral bone conduction hearing aid in children with unilateral atresia.

Improving Auditory Perception in Pediatric Single-Sided Deafness: Use of Cochlear Implants' Direct Connection for Remote Speech Perception Rehabilitation.

PURPOSE: Unilateral cochlear implants (CIs) can restore binaural hearing in single-sided deafness (SSD). Direct stimulation of the CI can be obtained via the Bluetooth connection of a device to the CI, thus excluding the typical-hearing ear. This study aims to investigate the use of CI connectivity features as a rehabilitative strategy in a small cohort of children affected by SSD. METHOD: A newly developed training protocol was presented to children with SSD who have less than 2 years of experience with CI. We developed a user-friendly and short-term (six sessions within 20 days) training protocol for speech perception that patients themselves can manage independently at home using CI connectivity systems. Children were telematically tested before and after the training by trained speech and language therapists. RESULTS: Four patients met the inclusion criteria. They all showed better results in the final online assessment, when compared with the initial one. CONCLUSIONS: To our knowledge, this is the first clinical focus article presenting an auditory training protocol for SSD patients with CI using the Bluetooth connectivity systems for teletherapy. The results, although preliminary, support the efficacy of this rehabilitative strategy. Further research is needed to support our findings.
