The National Institute on Deafness and Other Communication Disorders (NIDCD) awarded a $405,748 Project Grant (CFDA 93.173 - Research Related to Deafness and Communication Disorders) to the University of Wisconsin - Madison to develop and validate non-invasive aerodynamic assessment methods for evaluating voice disorders in children aged 4-17 years. The key objectives are to:

  1. Optimize aerodynamic assessment protocols by incorporating modifications such as shorter trial times, auditory masking, visual feedback, and cheek restraints to improve reliability in the pediatric population.

  2. Correlate aerodynamic parameters with other voice measures, including pediatric voice-related quality of life scores, lesion characteristics, clinician-based perceptual assessments, and acoustic analysis, to understand how aerodynamic input differs in children with voice disorders compared to healthy controls.

  3. Generate normative data ranges for aerodynamic parameters measured using mechanical airflow interruption techniques, addressing a critical gap in complete, objective, and reliable voice assessment for children.

The 5-year project, running from June 2025 to May 2030, aims to advance the state of pediatric voice evaluation and support improved diagnosis and treatment of voice disorders in children.
