Noninvasive Evaluation of the Biomechanical Accommodations to Bolus Volume during Human Swallowing

Figure 2

Temporal sequence of biomechanical events during oropharyngeal swallowing. The red line notes the swallowing sound as the reference time. T1, onset of hyoid slight movement; T2, onset of hyoid rapid movement; T4, onset of stationary phase of the hyoid; T5, offset of stationary phase of the hyoid; T6, offset of hyoid movement. T3 and T7 were confirmed to be meaningless for hyoid activity; Ch. 1–Ch. 5, Channel 1 to Channel 5.
