“…Various methods have been reported for tongue pressure measurements (Ono et al . ), including a small balloon‐type sensor, a linked three transducer array, a multiple‐point sensor sheet, etc. The Iowa Oral Performance Instrument (IOPI) has been used to evaluate swallowing pressure in healthy subjects as well as those with dysphagia.…”

“…However, the tongue muscles may become frail as a consequence of age-related changes or some diseases that contribute to oral and/or pharyngeal dysphagia (Nicosia et al 2000;Youmans and Stierwalt 2006).

Bolus swallowing can be a difficult task and/or highly hazardous to people with dysphagia (swallowing impairment), involving a risk of choking and airway obstruction. Food and pharmaceutical industries are under growing pressure to design and provide quality food for safe consumption by these disadvantaged populations and urgently need knowledge and a proper understanding of the controlling mechanisms of bolus manipulation and swallowing. In this study, physiological capabilities related to oral food handling, including maximum isometric tongue pressure, the volume of oral cavity, optimum bolus size, and tongue pressures applied during bolus swallowing were investigated. A total of 106 healthy subjects of different ages, genders and ethnic groups were involved in the investigation. A wide range of maximum isometric tongue pressure (from as low as 10 kPa to as high as 70 kPa) and maximum oral volume (from as low as 25 mL to as high as 116 mL) were observed. Further analysis showed that gender had no significant influence on tongue pressure and oral volume capacities. For younger adults (22-64 years), age also appears to have little effect. However, for older adults (>65 years), both maximum isometric tongue pressure and the oral volume showed a gradual decrease with the increasing of age. By investigating basic factors of bolus swallowing, this project aimed to reveal critical controlling factors underlining the process and to test the hypothesis that, because tongue pressure provides the initial driving force for bolus flow, one's capability to generate tongue pressure could be related to the ease with which one can swallow. For this purpose, a selection of subjects with known maximum isometric tongue pressure was further invited to swallow food (bolus) of varying consistencies. A positive correlation was observed between maximum tongue pressure and the maximum consistency of bolus that one can swallow for those who had lower tongue pressure generation capacity (<40 kPa). However, for subjects capable of producing very high tongue pressures (>40 kPa), a tongue pressure reserve (around a third of their maximum capability) was observed during bolus swallowing. PRACTICAL APPLICATIONSThis article investigates a few interesting hypothesis on the bio-mechanics of food processing, especially tongue pressure for bolus management and transfer during oro-pharyngeal swallow. Swallowing is the final stage of food oral processing and is crucial for the transportation of orally processed food (the bolus) to the stomach for further digestion and nutrient absorption. As such, safe swallowing is a major concern for many disadvantaged populations, e.g., some elderly populations, infants, oral and/or pharyngeal dysphagia and cerebrovascular accident (stroke) patients, patients in the late-stage of Alzheimer's disease and other hospital patients. Food and pharmaceutical industries are under an increasing pressure to develop and provide foods that are not only healthy and tasty, but are also safe to consume by these disadvant...

“…It is noteworthy that the original muscle patterns reported by Hannam et al were reported as being low in amplitude; therefore, muscle activation amplitudes could be increased and remain plausible. We also plan to investigate activating the tongue muscles in concert with the jaw muscles to simulate tongue movements [59] and palate contact pressure patterns [60] during the chewing cycle. Interestingly, this would add a dynamically changing inertia as opposed to the current passive tongue mass.…”

International audienceWe present an open-source physical simulation system suitable for efficient modeling of anatomical structures composed of both hard and soft tissue components, interconnected by point-wise attachments, contact, and other constraints. Specific attention is paid to the computational formulation needed for the coupled simulation of rigid and deformable structures, and a constraint-based mechanism is described for attaching these together. As an application of this system, we then present a novel 3D dynamic model of the jaw-tongue-hyoid complex, consisting of an FEM model of the tongue, rigid jaw, and hyoid structures, point-to-point muscle actuators, and constraints for bite contact and the temporomandibular joints. Several simulations are presented showing combined jaw-tongue actions and demonstrating the effects of coupled jaw-tongue-hyoid dynamics

“…The tongue is vital for moving and positioning food between the teeth, for selecting food fragments for further mastication, for mixing saliva with the food and for posterior transportation of the bolus into the oropharynx (Blissett et al 2007;Stone 2005). To perform these actions, the tongue must be able to perform tilting, rotating and pushing movements in different directions at different stages of mastication (Hiiemae and Palmer 2003;Mioche et al 2002;Ono et al 2009;Taniguchi et al 2013). Neuromuscular disorders of the central nervous system (e.g.…”
