Figure 2. Signal envelopes from the synchronized multimodal recordings. Multimodal recording of the envelopes for the
synchronized output of sonotubometry (A) and the electromyography (EMG) for the submental group (B), the tensor veli palatini
muscle (mTVP) (C), and the levator veli palatini muscle (mLVP) (D) during a swallow.

Figure 4. Average across participants of the displacement from baseline as assessed at each still frame of the video recording by
endoscopy during a swallow event. Shown are the changes in elevation of the soft palate representing levator veli palatini muscle
contraction (LVP), the displacement and degree of axial rotation for the medial lamina of the eustachian tube (ET) cartilage
(cartilage), the posterior displacement of the lateral wall of the ET lumen due to tensor veli palatini muscle contraction (TVP), and
the ET lumen opening (ETO).
