“…The pressure and the total work provided by the tongue 15 during the squeezing action of different jelly-type foods was recently studied (Yokoyama et al, 2014) and maximum pressures were measured in the range 5−40 kPa. Other groups (Nicosia et al, 2000;Youmans and Stierwalt, 2006) reported previously similar figures and highlighted also that pressure varies along the tongue position and is higher at the back. The mean peak tongue pressure 20 was also found to remain similar across different age groups, although maximum tongue strength was found to decrease with age (Youmans and Stierwalt, 2006;Utanohara et al, 2008).…”

“…Results (Yokoyama et al, 2014;Nicosia et al, 2000;Youmans and Stierwalt, 2006;Clavé et al, 2006). The movement of the roller induces a normal displacement of the soft membrane holding the liquid, toward the rigid top wall, similarly to the tongue approaching the palate.…”

“…Our theory and experiments can also help formulating a hypothesis concern-245 ing the higher pressure measured at the back of the tongue, during swallowing, by Nicosia et al (2000). The tongue and the bolus are initially static and because of the initial acceleration and the tongue inertia, the force exerted by the roller on the liquid and its pressure increase over time.…”

“…However, the Robbins et al exercise protocol focuses exclusively on strength and does not include actual swallowing tasks or other possible tongue-press tasks, such as those emphasizing precision, endurance, or speed. The fact that swallowing pressures are known to fall well short of those pressures registered in maximum isometric tasks [9] calls into question the emphasis on strength goals and outcomes in this approach.…”

“…For the current study, we studied partial-pressure amplitude targets in the range of 50 percent of each participant's maximum isometric pressure capacity (henceforth called "half-maximum tongue-palate press" tasks). The choice of this target range was motivated by previous evidence showing that habitual swallowing pressures typically fall in or below this halfmaximum range [9].…”

Abstract-Tongue-pressure resistance training is known to increase tongue strength in seniors and individuals with strokerelated dysphagia. However, evidence of associated functional improvements in swallowing is equivocal. We investigated similarities in pressure waveform profiles between swallowing and several tongue-palate pressure tasks to identify tasks that may be best suited for inclusion in tongue-pressure resistance training protocols for patients who are unable to safely perform real bolus swallows in treatment. Tongue-palate pressures were recorded in 20 healthy young adults. Participants performed water and nectarthick juice swallows, effortful and noneffortful saliva swallows, and "half-maximum" tongue-palate partial-pressure tasks emphasizing either anterior or posterior tongue-palate contact at different speeds. Pressure slopes (amplitude change over time) during the pressure application (rise) and withdrawal (release) phases were analyzed. A subset of four tasks with the greatest similarity in slope characteristics to those seen in bolus swallows was identified: anterior-emphasis half-maximum tongue-palate presses, posterior-emphasis maximum isometric tongue-palate presses, posterior-emphasis half-maximum slow tongue-palate presses, and effortful saliva swallows. We propose that future research should explore the degree to which swallowing improvements are obtained from treatment protocols that emphasize these tasks.

Background: Aberrations in the physiologic components of normal oropharyngeal swallowing have been linked to aspiration events and to predisposition to aspiration pneumonia, a common, deadly disease in elderly persons. Studies have demonstrated a temporal, physiologic link between breathing and the principal physiologic swallowing components involved in airway protection during swallowing. We developed a normative model of integrated breathing and swallowing patterns using concomitant videofluoroscopic images and nasal respiratory airflow recordings.Objectives: To establish normative temporal and respiratory-phase pattern relationships between breathing and swallowing in adult human beings across the aging continuum; to relate any alterations in these patterns to swallowing abnormality, an aspiration event during swallowing, and predisposition to aspiration pneumonia; and to develop clinically practical evaluation methods for identifying breathing and swallowing discoordination.Setting: Fluoroscopy suite in an acute care hospital.Participants: Eighty-two healthy adult volunteers gave informed consent. All eligible healthy volunteers were welcome and were screened for age, race, and sex for equal distribution of each.Intervention: Respiratory-phase patterns and the onset and duration of 11 predetermined swallowing events and associatedrespiratoryactivitieswerestudied.Allparticipants' single-liquidbariumswallowexaminationswerestudiedwith simultaneous videofluoroscopy and respiratory recordings.Main Outcome Measures: Onset of each of the 11 predetermined breathing and swallowing events was digitally recorded and analyzed. The phases of breathing before and after swallowing were identified. The presence, depth, and response to airway penetration were recorded and related to respiratory pattern.Results: Four respiratory-phase patterns were identified that changed with advanced age. The correlation analyses of the temporal breathing and swallowing events revealed a normal pattern of 4 clearly distinguishable functional units. Differences in apnea duration and apnea offset occurred with advanced age. Conclusion:This research provides evidence for clearly distinguishable patterns and functional groupings of breathing and swallowing events, a necessary first step toward determining whether abnormal breathing and swallowing patterns in patients with dysphagia are associated with health outcome.
