Trial Outcomes & Findings for Respiratory-Swallow Training in Veterans With Oropharyngeal Cancer (NCT NCT01032928)

NCT ID: NCT01032928

Last Updated: 2015-01-01

Results Overview

Respiratory swallow patterns were collected using nasal airflow and respiratory inductance plethysmography (RIP) of each swallow during the modified barium swallow study. The movements of the ribcage and abdomen were recorded using RIP; data synchronized and recorded using the KayPentax Digital Swallow Workstation Signals Lab. Subjects were categorized as optimal (expiratory-expiratory) versus non-optimal (non-expiratory-expiratory).

The penetration aspiration scale is a validated 8 point interval scale used to describe penetration and aspiration events. Scores are determined primarily by the depth to which material passes in the airway and by whether or not material entering the airway is expelled. Scores \< 3 are considered to be normal. For the purpose of our study scores were dichotimized to normal and impaired.
