Hearing Intervention Effects on Brain and Language Development in Children With Bilateral Mild Hearing Loss (HBD-RCT)

17 augusti 2026 uppdaterad av: Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University

Effects of Hearing Aid Intervention on Brain and Language Development in Children With Bilateral Mild Hearing Loss: A Multicenter Randomized Controlled Trial

This is a multicenter, prospective, randomized controlled clinical trial to evaluate the effects of hearing aid intervention on brain and language development in children with bilateral mild sensorineural hearing loss. Eligible participants will be randomly assigned (1:1) to either the hearing aid intervention group or the control group. The primary outcome is the general developmental quotient of the Griffiths Development Scales-Chinese Edition (GDS-C) at 12 months. Secondary outcomes include auditory and speech development, language development, adaptive behavior, and brain structure and function assessed by MRI. Follow-up assessments will be conducted at baseline, 6 months, and 12 months.

Intervention / Behandling
Experimentell: Hearing-aid intervention
Participants in the hearing-aid intervention group will receive standardized bilateral fitting of behind-the-ear (BTE) hearing aids, and their parents will be instructed to ensure consistent daily use for 12 months and be provided with essential knowledge regarding hearing aid maintenance and proper usage. In addition, the same hearing-care education sessions will also be delivered to this group.
Enhet: Behind-the-ear (BTE) hearing aids
Bilateral BTE hearing aids will be uniformly provided by the project team and fitted and verified by experienced audiologists at participating sites, with settings adjusted to achieve optimal hearing status according to individual needs. The devices will be selected from mainstream BTE hearing aid brands and models that are already commercially available in China and widely used in pediatric populations.
Övrig: Hearing-care educational sessions
Standardized educational sessions covering children hearing and speech development, pediatric hearing care, routine monitoring and detection, and appropriate family support and parent-child interaction delivered by trained researchers during each follow-up visit.
Övrig: Hearing-care education
Participants in the hearing-care education control group will not receive hearing aids, but will receive standardized hearing-care educational sessions at each follow-up visit.
Övrig: Hearing-care educational sessions
Standardized educational sessions covering children hearing and speech development, pediatric hearing care, routine monitoring and detection, and appropriate family support and parent-child interaction delivered by trained researchers during each follow-up visit.

Åtgärdsbeskrivning
Tidsram
Children overall development, as measured by General Developmental Quotient (GDQ) from the Griffiths Development Scales - Chinese Edition (GDS-C)
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
The GDS-C was adapted from the 2006 Griffiths Mental Development Scales - Extended Revised (GMDS-ER) and standardized with Chinese norms for children aged 0-8 years. It evaluates six subdomains: (A) Locomotor, (B) Personal-Social, (C) Language, (D) Eye & Hand Coordination, (E) Performance, and (F) Practical Reasoning. The General Developmental Quotient (GDQ) is derived as:(developmental age ÷ chronological age) × 100. Higher scores indicate better overall developmental status.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.

Including six subscales: Locomotor (A), Personal-Social (B), Language (C), Eye-hand Co-ordination (D), Performance (E), and Practical Reasoning (F). Each subscale quotient is calculated as (subscale developmental age ÷ chronological age) × 100. Higher subscale quotients indicate better performance in the specific domain.

Auditory Brainstem Response (ABR)
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Electrical potentials recorded with scalp electrodes in response to electrical stimulation of the cochlear nerve. The ABR threshold will be measured in decibels normal hearing level (dB nHL) for each ear. Lower thresholds indicate better auditory function.

From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Categories of Auditory Performance (CAP) Score
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
The Categories of Auditory Performance (CAP) is a hierarchical rating scale assessing real-life auditory functioning. It comprises 10 categories graded from 0 to 9, where 0 = "cannot detect environmental or speech sounds" and 9 = "able to use the telephone with an unfamiliar speaker in unpredictable situations". Higher scores indicating better auditory performance.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Speech Intelligibility Rating (SIR) Score
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
The Speech Intelligibility Rating (SIR) is a hierarchical rating scale assessing the intelligibility of a child's speech in everyday communication. It comprises 5 categories graded from 1 to 5, with higher scores indicating greater speech intelligibility.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Meaningful Auditory Integration Scale (MAIS/IT-MAIS) Score
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
This scale includes the original MAIS version for children aged ≥3 years and the IT-MAIS (Infant-Toddler version) for children <3 years. It is a parent-report structured interview designed to assess the child's spontaneous auditory responses in everyday environments, consisting of 10 items evaluating three domains: vocalization behavior, alerting to sounds, and deriving meaning from sound. Each item is scored from 0 to 4, yielding a total score ranging from 0 to 40. Higher scores indicate better auditory integration ability.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Meaningful Use of Speech Scale (MUSS) Score
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
The Meaningful Use of Speech Scale (MUSS) assesses speech production and communication ability. It comprises 10 open-ended questions answered by parents/guardians, each scored 0-4). The total score ranges from 0 to 40, with higher scores indicating better speech use. Scores are often reported as percentages (score ÷ 40 × 100%).

Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
The ABAS-II is a comprehensive, norm-referenced assessment of adaptive functioning across multiple skill areas relevant to daily living. Depending on the respondent form used, it yields a General Adaptive Composite (GAC) as an overall standard score (mean = 100, SD = 15), three domain composite scores (Conceptual, Social, and Practical), and individual skill area scaled scores covering domains such as Communication, Community Use, Functional Academics, Home Living, Health and Safety, Leisure, Self-Care, Self-Direction, Social, Work (where applicable), and Motor. Higher scores consistently indicating more advanced adaptive functioning.

Distortion Product Otoacoustic Emissions (DPOAE) Amplitude and Signal-to-Noise Ratio
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
DPOAEs were recorded bilaterally at standard frequencies. For each frequency, the DPOAE amplitude (in dB SPL) and signal-to-noise ratio (SNR, in dB) were obtained. The amplitude represents the absolute sound pressure level of the distortion product response, while the SNR is the difference between the amplitude and the background noise floor at the same frequency. Higher amplitude and SNR indicate stronger outer hair cell (OHC)-mediated cochlear amplification and better cochlear function. A DPOAE response is conventionally considered present (PASS) when the SNR exceeds 6 dB.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Acoustic Immittance
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Acoustic immittance is measured via tympanometry using a 226-Hz probe tone. Three quantitative parameters are reported: tympanometric peak pressure (measured in daPa), peak compensated static admittance (measured in mmho), and equivalent ear canal volume (measured in mL). Results are classified as pass or fail based on standardized criteria.
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Family Environment Survey
Tidsram: From enrollment to 12 months, with assessments at 0, 6, and 12 months.
Including basic family environment survey, and Index of Child Care Environment (ICCE)
From enrollment to 12 months, with assessments at 0, 6, and 12 months.
