Exploring the Differences Between an Immature and a Mature Human Auditory System Through Auditory Late Responses in Quiet and in Noise.

Children are disadvantaged compared to adults when they perceive speech in a noisy environment. Noise reduces their ability to extract and understand auditory information. Auditory-Evoked Late Responses (ALRs) offer insight into how the auditory system can process information in noise. This study investigated how noise, signal-to-noise ratio (SNR), and stimulus type affect ALRs in children and adults. Fifteen participants from each group with normal hearing were studied under various conditions. The findings revealed that both groups experienced delayed latencies and reduced amplitudes in noise but that children had fewer identifiable waves than adults. Babble noise had a significant impact on both groups, limiting the analysis to one condition: the /da/ stimulus at +10 dB SNR for the P1 wave. P1 amplitude was greater in quiet for children compared to adults, with no stimulus effect. Children generally exhibited longer latencies. N1 latency was longer in noise, with larger amplitudes in white noise compared to quiet for both groups. P2 latency was shorter with the verbal stimulus in quiet, with larger amplitudes in children than adults. N2 latency was shorter in quiet, with no amplitude differences between the groups. Overall, noise prolonged latencies and reduced amplitudes. Different noise types had varying impacts, with the eight-talker babble noise causing more disruption. Children's auditory system responded similarly to adults but may be more susceptible to noise. This research emphasizes the need to understand noise's impact on children's auditory development, given their exposure to noisy environments, requiring further exploration of noise parameters in children.

Screening for Auditory Processing Disorder in French-Speaking School-Age Children: A Pilot Study.

OBJECTIVES: A few clinical screening tools for auditory processing disorder (APD) are currently available. However, most of these tools are in English and cannot be used to screen individuals with a first language other than English. This study aimed to develop an APD screening test battery in French and to assess its psychometric properties in detecting school-age children at risk of APD. METHOD: Prior to their complete audiological APD assessment, 53 children (7-12 years old) were recruited from an audiology clinic. The APD assessment lasted between 2 and 3 hr, including 15-20 min for the screening test battery. The screening test battery was composed of four behavioral subtests and two questionnaires (parent and teacher). RESULTS: When combined, two among the four behavioral subtests showed a sensitivity of 100% and a specificity of 80%. CONCLUSION: The newly developed screening tool could help reduce the number of unnecessary APD assessments, therefore allowing early diagnosis in children with APD and increasing their chances of receiving adequate intervention.

Assessing Auditory Processing in Children with Listening Difficulties: A Pilot Study.

BACKGROUND: Auditory processing disorders (APD) may be one of the problems experienced by children with listening difficulties (LiD). The combination of auditory behavioural and electrophysiological tests could help to provide a better understanding of the abilities/disabilities of children with LiD. The current study aimed to quantify the auditory processing abilities and function in children with LiD. METHODS: Twenty children, ten with LiD (age = 8.46; SD = 1.39) and ten typically developing (TD) (age = 9.45; SD = 1.57) participated in this study. All children were evaluated with auditory processing tests as well as with attention and phonemic synthesis tasks. Electrophysiological measures were also conducted with click and speech auditory brainstem responses (ABR). RESULTS: Children with LiD performed significantly worse than TD children for most behavioural tasks, indicating shortcomings in functional auditory processing. Moreover, the click-ABR wave I amplitude was smaller, and the speech-ABR waves D and E latencies were longer for the LiD children compared to the results of TD children. No significant difference was found when evaluating neural correlates between groups. CONCLUSIONS: Combining behavioural testing with click-ABR and speech-ABR can highlight functional and neurophysiological deficiencies in children with learning and listening issues, especially at the brainstem level.

Traduction franco-canadienne de l'Assessment of Systematic Reviews Revised (AMSTAR 2) : validation transculturelle et fidélité interjuges.

Objective: Produce a French-Canadian translation of AMSTAR 2, affirm its content validity, and examine interrater reliability. Methods: Based on Vallerand's methodological approach, we conducted forward and parallel inverse-translations. Subsequently, an expert panel evaluated the translations to create a preliminary experimental French-Canadian version. A second expert panel examined this version and proposed additional modifications. Twenty future health professionals then rated the second experimental version for ambiguity on a scale (from 1 to 7). The principal co-investigators then reviewed the problematic elements and proposed a pre-official version. To ascertain content validity, a final back-translation was conducted resulting in the official version. Four judges evaluated 13 systematic reviews using the official French-Canadian version of AMSTAR 2. The Kappa coefficient was used to evaluate interrater reliability. Results: This rigorous adaptation enabled the development of a Franco-Canadian version of AMSTAR 2. Its application demonstrated low ambiguity (mean 1.15; SD 0.26) as well as good overall interrater reliability (total κ > 0.64) across all items. Conclusion: The French-Canadian version of AMSTAR 2 can now support francophone clinicians, educators, and managers in Canada as they undertake evidence-based practice.

The management of lower back pain using pilates method: assessment of content exercise reporting in RCTs.

PURPOSE: To evaluate the quality of the reporting of exercise interventions with Pilates method for the treatment of lower back pain (LBP) in adults. MATERIALS AND METHODS: Two independent evaluators selected randomized controlled trials (RCTs) of moderate and high methodological quality included in a Cochrane Systematic Review (SR) and from an additional updated search in the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, PEDro and SPORTDiscus. Three assessment tools (Consensus on Therapeutic Exercise Training (CONTENT) scale, Template for Intervention Description and Replication (TIDieR) checklist and Consensus on Exercise Reporting Template (CERT) checklist) were utilized by three pairs of two independent researchers trained. The scales' concordance was measured using the Kappa coefficient. RESULTS: Ten RCTs were included. The CONTENT scale score was 5.3 (± 1.33) out of 9 points; the TIDieR checklist was 8.5 (± 1.71) out of 12 points and the CERT checklist was 9.5 (± 3.62) out of 19 points. The CONTENT and CERT had moderate concordance, while there was fair concordance between the other tools. CONCLUSIONS: The overall reporting quality for the Pilates exercises in ten moderate-to-high quality RTCs for the management of LBP was low according to CONTENT scale and CERT checklist and high according to TIDieR checklist.Implications for RehabilitationReporting of Pilates exercise program in moderate-to-high quality RCTs for the management of lower back pain remains incomplete.Pilates exercise program should be personalized and contextualized to individual participants.There may be a need to consider adding to or combining the information available from various trials.
