Abstract

It is well known that the brain-injured patients with tracheostomy is prone to frequent tracheopulmonary aspiration and dysphagia problems. We experienced two brain-injured patients with dysphagia, who revealed the improvement of clinical and videofluoroscopic parameters after application of Passy-Muir speaking valve (PMV 2000^Ⱂ, Passy-Muir Inc., USA). Two brain-injured patients had kept on nasogastiric and tracheostomy tubes. After PMV application for 2weeks, the frequency of aspiration decreased, sleep hygiene and emotional lability improved, and also videofluoroscopic parameters such as pharyngeal delay time, pharyngeal transit time, and epiglottic closure were improved. Eventually, they could be free from tracheostomy tubes within 1 month after PMV application. (J Korean Acad Rehab Med 2005; 29: 225-230)
