Research Abstract

Swallow maneuvers showed the earliest and fine arytenoids closure and reduced bolus progress among all maneuvers. The humming swallow is most effective maneuver that reduced the stage II transport. Those may work for the protection against aspiration especially in the chew swallow of dysphasic patients.
