简要总结
This study aims to compare pulmonary function and respiratory muscle strength between children with hearing impairment and their healthy peers. Hearing plays a critical role not only in communication but also in cognitive, sensory, and psychomotor development. Children with hearing impairment may experience balance and coordination problems, vestibular dysfunction, and reduced muscle strength, which may negatively affect respiratory function.
Although several studies have evaluated pulmonary function in children with hearing impairment, research investigating respiratory muscle strength in this population is limited. To our knowledge, no peer-reviewed study has directly compared respiratory muscle strength between children with hearing impairment and healthy controls.
This study will compare spirometric parameters and respiratory muscle strength measurements between children with hearing impairment and age-matched healthy controls.

研究组 & 干预措施
Children With Hearing Loss
Children aged 7-16 years diagnosed with hearing loss. Participants will undergo pulmonary function testing using spirometry and assessment of respiratory muscle strength (maximum inspiratory pressure [MIP] and maximum expiratory pressure [MEP]).
Healthy Controls
Age- and sex-matched healthy children aged 7-16 years without hearing impairment. Participants will undergo pulmonary function testing using spirometry and assessment of respiratory muscle strength (maximum inspiratory pressure [MIP] and maximum expiratory pressure [MEP]).
结局指标
主要结局
Maximum Inspiratory Pressure (MIP)
时间窗: At baseline (single assessment)
Respiratory muscle strength assessed by measuring maximum inspiratory pressure (cmH₂O) using a portable electronic mouth pressure device (MicroRPM) according to ATS/ERS guidelines.
Maximum Expiratory Pressure (MEP)
时间窗: At baseline (single assessment)
Forced vital capacity measured by spirometry (COSMED Pony FX) according to ATS/ERS criteria; values expressed as absolute and percentage of predicted values.
次要结局
- FEV1/FVC Ratio(At baseline (single assessment))
- Peak Expiratory Flow (PEF)(At baseline (single assessment))
- Forced Expiratory Flow 25-75% (FEF25-75%)(At baseline (single assessment))
- Forced Vital Capacity (FVC)(At baseline (single assessment))
- Forced Expiratory Volume in 1 Second (FEV1)(At baseline (single assessment))
