Document Summary

Oral prepatory phase: breakdown occurs when lips, cheek, tongue, and mandible do not function (jaw/jawbone, results fro(cid:373) strokes, parki(cid:374)so(cid:374)"s disease, a(cid:374)d head a(cid:374)d (cid:374)eck ca(cid:374)cers. Characteristics: decreased lip closure, making it difficult to take in food/liquid from eating or drinking utensils, leading to leakage, problem controlling ingested materials, where food/liquids fall in space between teeth and gums, difficulty biting or chewing bolus (food) Inefficient oral preparation due to weakness of tongue (more time needed to prepare bolus) Impaired sensitivity of tongue, lips and other oral structures (food positioning and management) Oral phase: formed bolus moves back of mouth towards pharynx to trigger the swallow, results from people with strokes, progressive neurological diseases (als), tooth loss. Characteristics: difficulty bolus to the pharynx (resulting in residual food/liquid in the mouth, delayed initiation of bolus movement, increasing time to from oral to pharyngeal phase.
