Figure 2.

Thoracic movement over a portion of a feeding sequence with swallows indicated by dotted lines. All data consisted of complete sequences of more than 50 swallows. 10–20 swallows per sequence were identified and selected from the XROMM visual data. The time equivalent data from the respiratory data were then extracted using the synchronization signal recorded on both data traces. In this example, neither respiration nor swallowing were regular.
