Intrarater and interrater reliability for measurements in videofluoroscopy of swallowing

In order to achieve reliable measurements in videofluoroscopy of swallowing, it is recommended that raters use well-defined guidelines for the levels of ordinal visuoperceptual variables. Furthermore, in order to make the measurements reliable (intrarater and interrater) it is recommended that, following protocolled pre-experimental training, the raters should have maximum consensus about the definition of the measured variables.
