According to VFSS
observation, Rofes et al . have found that pudding bolus could reduce the leakage and aspiration rate to 98.9%, which was confirmed by electrophysiological activity.
We used 2 instrumental methods, FEES and VFSS
, to evaluate all 3 phases of dysphagia; these methods are considered the reference standards for instrumental evaluation of all phases of dysphagia.

helps to identify not only functional but also structural anomalies of anatomic regions studied during the procedure .

All items of SDQ-P were uniformly in English version and all the patients answered the SDQ-P before VFSS
To overcome this issue Variable-sized frequency selective structures (VFSS
) are designed to overcome mutual coupling for ultra wide bandwidth.
Ninety-five percent (n=94) underwent a VFSS
is distinct from many other radiographic examinations because of its ability to not only diagnose dysphagia, but also to verify the immediate effectiveness of treatment strategies in order to generalize the results when recommending a diet.
A video fluoroscopic swallow study (VFSS
), also called a modified barium swallow, has been the traditional method of instrumental assessment, and until recently it was the gold standard for dysphagia evaluation.
Typically a virtual server would be configured with client access ports, VFSs
, and an administrator.
In this event, silent aspiration is suspected, and more extensive objective testing such as the modified barium swallow (MBS) also known as the videofluoroscopic swallow study (VFSS
), or fiberoptic endoscopic evaluation of swallowing (FEES) may be required (Garon, Engle, & Ormiston, 1996) (see Table 6).
