Comparison of Pulmonary Functions and Respiratory Muscle Strength Between Children With Hearing Impairment and Healthy Peers

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.
