Swallowing was assessed at the basal OVD and with incremental increases of 2, 4, and 6\u2009mm using hard wax stops under two conditions: saliva swallowing (SS) and yogurt swallowing (YS). Tongue pressure was measured with a Flexiforce A\u2010201 sensor, and EMG activity of the masseter and temporalis muscles was recorded using EMG Works 4.0.7 (Delsys, USA). Each participant performed three swallows per condition, and the average of the three trials was used for analysis. Comparisons between conditions were made using ordinary least squares linear regression, with a significance level of\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05 and 95% confidence intervals.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No significant differences in EMG activity were observed for the temporalis or masseter muscles across the different OVD conditions during SS (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u20090.05).
