Purpose When swallowing efficiency is impaired, residue accumulates in the pharynx. Cued or spontaneous swallows in the head neutral position do not always successfully clear residue. We investigated the impact of a novel maneuver on residue clearance by combining a head turn with the chin down posture.

The objective of this study was to compare the outcomes of two tongue resistance training protocols. One protocol ("tongue-pressure profile training") emphasized the pressure-timing patterns that are typically seen in healthy swallows by focusing on gradual pressure release and saliva swallowing tasks. The second protocol ("tongue-pressure strength and accuracy training") emphasized strength and accuracy in tongue-palate pressure generation and did not include swallowing tasks.

Purpose: As many as 74% of residents in long-term care (LTC) are anticipated to have swallowing difficulties (dysphagia). Low food intake is commonly reported in persons with swallowing problems, but food intake may also be affected by fatigue in the swallowing muscles. As fatigue sets in during mealtimes, the strength of the tongue may decline.

Determining the co-occurrence of malnutrition and dysphagia is important to understand the extent to which swallowing impairment contributes to poor food intake in long-term care (LTC). This review investigated the impact of dysphagia on malnutrition in LTC by synthesizing the results of published literature. Seven electronic databases were used to search for English-language publications reporting malnutrition and dysphagia in LTC facilities from 1946 to 2013.

Purpose: The purpose of this study was to investigate whether an emergent literacy professional development program enhanced educators' use of vocabulary-teaching strategies during shared reading with small groups of pre-schoolers.

Method: Thirty-two pre-school educators and small groups of pre-schoolers from their classrooms were randomly assigned to experimental or comparison groups. The 15 educators in the experimental group received four in-service workshops as well as five individualized classroom coaching sessions.

Texture modification has become one of the most common forms of intervention for dysphagia, and is widely considered important for promoting safe and efficient swallowing. However, to date, there is no single convention with respect to the terminology used to describe levels of liquid thickening or food texture modification for clinical use. As a first step toward building a common taxonomy, a systematic review was undertaken to identify empirical evidence describing the impact of liquid consistency and food texture on swallowing behavior.
