|---|---|
| Oral Transit time (OTT) | the time taken from the initiation of the tongue movement to begin the voluntary oral stage of the swallow until the bolus head reaches the point where the lower mandible crosses the tongue base |
| Pharyngeal delay time (PDT) | when the bolus head reaches the point where the lower edge of the mandible crosses the tongue base and ends when laryngeal elevation begins in the context of the rest of the swallow |
| Pharyngeal transit time (PTT) | the time elapsed from the triggering of the pharyngeal swallow until the bolus tail passes through the cricopharyngeal region or the pharyngoesophageal (PE) segment. |
| Cannot hold fold in the mouth anteriorly | reduced lip closure (D/O Oral Prep Phase) |
| Cannot hold a bolus: if patient has reduced ability to shape the tongue around the liquid or paste, he/she will be unable to hold the liquid into cohesive bolus and material will spread throughout oral cavity | Reduced tongue shaping/coordination (D/O Oral Prep Phase) |
| Cannot form a bolus: when patient is finished with mastication, food is pulled together into a single bolus. If patient has reduced range or coordination of tongue movement, he/she will have difficulty in pulling this food into cohesive bolus | Reduced range of tongue motion or coordination (D/O Oral Prep Phase) |
