Aerodynamic and Acoustic Characteristics of Nasal Airflow in Parkinson's Disease

Key Points

• This research investigates how nasal airflow and velopharyngeal function are affected during vocal tasks in Parkinson's Disease.
• Analyzed velopharyngeal function during different vocal tasks
• Evaluated the intensity-airflow relationship in Parkinson's Disease
• Compared performance across rapid motor sequences and vowel production
• Velopharyngeal dysfunction worsened during rapid motor sequences compared to vowel production
• Greater vocal intensity increases motor deterioration of velopharyngeal function
• Dysfunction may serve as a marker for the severity of axial motor symptoms
