“…There was a reduction in the duration of the respiratory cycle during mastication and an increase during swallowing (15) . In healthy individuals, the times among swallowing events increased by age (16) .…”

“…The use of control groups and participants' ages also varied among the reviewed studies. Studies were performed with healthy subjects to obtain baseline data (6,12,14,16) and with patients with specific pathologies (5,13,17) . Studies of specific pathologies had well-formed research groups but did not always include control groups.…”

“…An experimental study (16) identified and characterized the temporal relation of selected structural movements during oropharyngeal swallowing. The authors sought to identify the movement patterns and determine whether the aging and/ or bolus features affected the temporal relations.…”

Purpose: To analyze published international scientific papers on the physiology of deglutition in oral and pharyngeal phases, considering different food consistencies: nectar, honey, pudding, pasty heterogeneous, semi-solid, and solid. Methods: This is a qualitative literature reviews. The studies considered were selected on PubMed, using the keywords "Swallowing and consistency", "Swallowing and solid", and "Swallowing and pasty", limiting the search to manuscripts published in English in the period between 2005 and 2010, and conducted with human beings over 18 years old. The methodology involved question formulation, location and selection of studies, and critical analyses of the manuscripts, according to the concepts of the Cochrane Handbook. Results: Two hundred and eleven studies were identified, out of which only 18 allowed access to the full text and were directly related to the theme. Conclusion:The studies presented very few similarities between the applied methodologies, especially when considering assessment methods.Overall, the studies were conducted with healthy individuals or with a specific pathology, without presenting the comparison with control cases. The heterogeneity of studies allows the investigation of different swallowing disorders. However, methodological variability makes it difficult to define and generalize the identified swallowing patterns. For this reason, it is not possible to identify parameters on which to base the clinical practice of speech-language therapists, especially when considering the normal or altered physiology of swallowing different food consistencies.

“…A further reason may be that in some subjects there may be negligible R-R heart-rate variability associated with swallowing. Lastly, other authors have described differences in subjects' ages and the characteristics of the swallowed bolus (i.e., volume and consistency) that could affect the degree of pharyngeal movement (17,18).…”

Purpose: To improve three-dimensional (3D) volume-selective turbo spin-echo (TSE) carotid wall imaging by the addition of a novel body surface swallowing detection device. Material and Methods:A 3D volume-selective TSE sequence was used to image the carotid artery. A novel carbon-fiber motion device, positioned over the laryngeal prominence, was used to detect swallowing movement. An electrical output generated by coil movement was used to detect motion, and an algorithm was programmed to reject data acquired during swallowing and for a short period afterwards. Images were acquired with and without the algorithm and scored on a scale of 0 -5 by four independent blinded observers according to the clarity of the vessel wall, e.g., 0 ϭ poor image quality and 5 ϭ excellent quality images with little or no artifact. Results:The scans with the rejection algorithm on were scored higher than the scans without the algorithm. The comparison of scores with the algorithm on vs. the algorithm off were as follows: mean Ϯ standard deviation (SD) ϭ 3.76 Ϯ 0.25, 95% confidence interval (CI) ϭ 3.27-4.25 vs. 2.64 Ϯ 0.25, 95% CI ϭ 2.15-3.13; with good interobserver correlation (Kendall's W score 0.77). Conclusion:Image quality can be improved by the algorithm during acquisition. This can be achieved by a novel, anatomically positioned superficial device. This may help in prolonged 3D scans where a single movement can corrupt the entire acquisition.

“…any research studies have explored the sequence of the events of swallowing and have revealed that there is considerable variability between and within healthy individuals (Cook et al, 1989;Gay, Rendell, Spiro, Mosier, & Lurie, 1994;Kendall, 2002;Kendall, Leonard, & McKenzie, 2003;Kendall, McKenzie, Leonard, Gonçalves, & Walker, 2000;Logemann et al, 2000;Logemann, Pauloski, Rademaker, & Kahrilas, 2002;McConnel, Cerenko, Jackson, & Guffin, Jr., 1988;Mendell & Logemann, 2007;Ohmae, Logemann, Kaiser, Hanson, & Kahrilas, 1995). Factors contributing to this variability include bolus volume, bolus consistency, age, and gender (Cook et al, 1989;Kendall, 2002;Kendall et al, 2003;Logemann et al, 2000Logemann et al, , 2002Mendell & Logemann, 2007;Ohmae et al, 1995).…”

Purpose: This study investigated the effect of the chindown posture on the sequence of swallowing events in healthy adults. Method: Sixteen healthy participants performed 45 5-ml thin liquid swallows during videofluoroscopy: 5 neutral head position, 30 chin-down posture, and then 10 neutral head position. Eight swallowing events were measured: the time of hyoid burst, bolus head in the pharynx, bolus tail in the pharynx, laryngeal vestibule closure (LVC), upper esophageal sphincter (UES) opening, bolus head in the UES, bolus tail exiting the pharynx, and laryngeal vestibule opening (LVO).Results: Our key finding is that LVC was one of the first 3 swallowing events in 69% of neutral swallows and in 78% of chin-down swallows ( p = .006). Also, LVO occurred last in 14% of chin-down swallows but never occurred last in the preceding neutral swallows ( p ≤ .001). Thus, in chin-down swallows, LVC occurred earlier and LVO occurred later. Conclusions:The chin-down posture may be beneficial for individuals with delayed onset of LVC and reduced duration of the LVC. Future studies are needed to examine this effect in individuals with dysphagia.

Temporal Sequence of Swallow Events During the Oropharyngeal Swallow

Abstract: Temporal relations between structural movements are not fixed but can be systematically affected by bolus characteristics and age.
