Abstract
- Videofluoroscopic swallowing study (VFS) is accepted as a gold standard tool for evaluating dysphagia. The real time video radiographic image provides visualization of the structures, movement, and coordination of swallowing. Abnormal oropharyngeal and esophageal anatomy can be readily identified. There are several scoring systems for analyzing VFS; A Penetration-Aspiration Scale (PAS), The Dysphagia Outcome and Severity Scale (DOSS), National Institutes of Health Swallowing Safety Scale (NIH-SSS) and Videofluoroscopic Dysphagia Scale (VDS). They can provide reliable quantification of selected events observed during VFS and be used as powerful outcome measures to investigate the efficacy of various swallowing treatments. This article reviews these scoring systems.
