The videofluoroscopic dysphagia scale (VDS) was developed as an objective predictor of the prognosis of dysphagia after stroke. We evaluated the clinical validity of the VDS for various diseases. We reviewed the medical records of 1,995 dysphagic patients (1,222 men and 773 women) who underwent videofluoroscopic studies in Seoul National University Hospital from April 2002 through December 2009. Their American Speech-Language-Hearing Association's National Outcome Measurement System (ASHA NOMS) swallowing scale, clinical dysphagia scale (CDS), and VDS scores were evaluated on the basis of the clinical and/or videofluoroscopic findings by the consensus of two physiatrists. The correlations between the VDS and the other scales were calculated. The VDS displayed significant correlations with the ASHA NOMS swallowing scale and the CDS in every disease group (p < 0.001 in all groups, including central and peripheral nervous system disorders), and these correlations were more apparent for spinal cord injury, peripheral nerve system disorders, and neurodegenerative diseases (correlation coefficients between the VDS and the ASHA NOMS swallowing scale: -0.603, -0.602, and -0.567, respectively). This study demonstrated that the VDS is applicable to dysphagic patients with numerous etiologies that cause dysphagia.
