Figure 1
Single frame of the videofluoroscopic recording showing the landmarks used for spatial measurements. Extent of movement of the hyoid bone in the x-y coordinate system. The square encloses four electrodes in position during status “electrical current off,” the oval includes the marked hyoid bone, and the circle indicates the x-y coordinate system.
