Temporal and Physiologic Measurements of Deglutition in the Upright and Supine Position with Videofluoroscopy (VFS) in Healthy Subjects.

Cross-sectional imaging has long been employed to examine swallowing in both the sagittal and axial planes. However, data regarding temporal swallow measures in the upright and supine positions are sparse, and none have employed the MBS impairment profile (MBSImP). We report temporal swallow measures, physiologic variables, and swallow safety of upright and supine swallowing in healthy subjects using videofluoroscopy (VFS).
