Training Swallowing Initiation During Expiration: Impact on Safety and Efficiency Following Treatment for Oropharyngeal Head and Neck Cancer
Head and neck cancers have escalated to epidemic levels in the United States, and survivors are suffering from life-long, devastating swallowing disorders with limited therapeutic options. This clinical trial investigates a novel swallowing treatment that trains initiation of swallowing during the expiratory phase of respiration to improve swallowing safety and efficiency.
