Fig. 5. A sequence (frames 1-22) showing swallowing of a polyethylene tube and its associated kinematic measures. Frames are acquired in 155 ms and are separated by 310 ms. The top row shows the high-temporal-resolution data; the middle row shows these images with the kinematic measures (described in Fig. 4) superimposed and the bottom row shows the kinematic measures alone. This corresponds to swallow 4, data for which are shown in part D of Figs 7,8,9,10,11,12,13.
