Food Transit Duration is Associated with the Number of Stage II Transport Cycles when Eating Solid Food

In the traditional description of swallowing, the oral phase has been sub-divided into the oral preparatory phase and the oral propulsive phase (Logemann, 1998). During the oral preparatory phase, food is taken into the oral cavity, masticated, mixed with saliva, re-collected by the tongue, and shaped into a bolus in preparation for transport into the pharynx when swallowing is initiated. The oral propulsive phase of swallowing is the propulsion of the bolus into the pharynx. Although this simple, 2-phase model has served clinicians well as a rudimentary description of the oral stage of ingesting liquids, it does not accurately portray mastication and swallowing of solid foods (Dua, Ren, Barden, Xie,& Shaker, 1997; Feinberg, 1993; Linden, Tippett, Johnston, Siebens,& French, 1989).
