Figure 3. Characteristics of jaw and soft palate motion cycles. Data from all recordings for each stage in the sequence were pooled. (a) Temporal relationship between jaw and SP movement for the 4 stages of the sequence; movement amplitudes are on a binary scale. Dark lines represent the jaw, lighter lines the SP. (b) The 2 types of OPAT cycles: with and without stage II transport (see Fig. 2b). The vertical scale is the same as in (a). (c) The average duration (mean, SD) for each phase in the SP cycle and (d) the jaw cycle. Data from all subjects, all cycles (see Table 1 for the N of each column). Mixed-model ANOVA was used, and the asterisks (* and **) indicate a statistically significant difference (P < 0.05 and P < 0.001, respectively). When appearing over a bracket between 2 columns, the asterisk indicates that the values in the 2 columns are significantly different. Abbreviations are defined in the text.
