Not Applicable

• Conditions: healthy adult subjects

• Registration Number: JPRN-UMIN000027536
• Lead Sponsor: Fujita Health University

Brief Summary

The oral transit time of the 3 ml bolus was significantly shortened by reclining position. The duration of laryngeal closure was prolonged significantly at 3 ml bolus swallowing with reclining position. In some cases, laryngeal closure started earlier in reclining position when swallowing 3 ml bolus. The 3 ml bolus head did not reach to hypopharynx except for one subject when reclined. At 20 ml bolus swallowing, the timing and duration of swallowing did not change regarding to the reclining position. The comparison of 3 ml and 20 ml bolus showed significant change at all swallowing events investigated.
