chin tuck vs chin down

Google Scholar. A total of 40 healthy volunteers (20 men and 20 women) swallowed 10 mL of diluted barium solution in a ‘‘normal and comfortable’ ’ position (NEUT), a comfortable chin-down position (DOWN), and a strict chin-tuck position (TUCK). However, the maximal vertical displacement of the hyoid bone was not significantly different among the three postures. Phys Med Rehabil Clin N Am 19: 691–707, vii. The y-axis was defined as the line connecting the anterior–inferior corners of the C2 through C4 vertebrae. 4e, f). The coordination of the kinematic analysis and the selected anatomical points. Leigh, JH., Oh, BM., Seo, H.G. Okada S, Saitoh E, Palmer JB, Matsuo K, Yokoyama M, Shigeta R, Baba M. What is the chin-down posture? What you have is a hyperdynaminc chin ptosis, a chin deformity which is largely absent at rest but becomes pronounced with smiling. Epub 2019 Aug 20.

Despite the wealth of studies, changes in the movement of swallowing structures in different neck postures have not been evaluated extensively. J Physiol. Resting state anatomy and kinematic changes were analyzed and compared between postures. The mean ARA in NEUT had a significantly smaller angle (11.6 ± 6.5 degrees) than in TUCK (43.3 ± 12.2 degrees, p < 0.002) or DOWN (45.7 ± 9.7 degrees, p < 0.001) postures, but a significant difference was not observed between TUCK and DOWN. When the extrinsic flexors are dominant the chin will translate forward instead of tucking in towards the neck as the head lifts. TUCK facilitated movement of the epiglottic base upward (TUCK vs. NEUT, 15.8 ± 4.7 vs. 13.3 ± 4.5 mm; p < 0.01). Logemann JA, Pauloski BR, Rademaker AW, Colangelo LA, Kahrilas PJ, Smith CH. We suppose that the epiglottic base can, at least in part, play a role as a surrogate marker for tongue base movement, because it is located at the lower end of the tongue base. Because each subject spent different amounts of time performing the swallowing test, a temporal normalization was required. After the temporal–spatial normalization, the pooled average trajectory and distributed range of motion were presented, respectively, as a series of mean values and band ranges obtained from elliptical distributions within 95 % confidence intervals (mean ± 2SEM) in both the x-axis and y-axis directions at each time step. PubMed  Otolaryngology Head and Neck Figure 4 shows an example of the change in trajectory of the hyoid bone in each posture. The chin-down, head rotation, head tilting, supraglottic swallowing, and Mendelsohn’s maneuvers are examples of commonly used strategies [2, 3]. The Chin Tuck Against Resistance (CTAR) exercise can be done using any flexible device (a ball, towel, etc. As compared to NEUT posture, DOWN resulted in a reduction of the vertical (p = 0.026) and horizontal (p < 0.001) displacements of the vocal cords.

Values of p ≤ 0.05 were considered statistically significant for all comparisons. However, Bülow et al. - 199.247.14.245. We evaluated not only the maximal excursion distances and velocities, but also the trajectories of the major structures. The trajectories of the epiglottic base during swallowing in a neutral (d), a comfortable chin-down (e), and a strict chin-tuck (f) posture are shown. Mean displacement magnitudes and standard deviations of the hyoid bone and larynx in NEUT were similar to data reported in previous kinematic analysis studies [14]. 2001;82:1255–60. The following variables were measured: (a) the chin-cervical spine, epiglottic base-cervical spine, and epiglottic base-arytenoid distances (mm) at rest just before swallowing; (b) the maximal vertical and horizontal excursions (mm) of the hyoid, epiglottic base, and vocal cords (upper margin of the subglottic airway column), defined as the maximal distance from the starting point of each structure to the point of maximal excursion along each direction; the maximal 2D excursion of the hyoid, epiglottic base, and vocal cords, defined as the maximal distance from the starting point of each structure to the point of maximal excursion; and the maximal flip angle (degrees, °) of the epiglottis during swallowing; (c) the maximal vertical and horizontal 2D velocities (mm/s) of the hyoid, epiglottic base, and vocal cords, defined as the points with maximal velocity along each direction; and the velocity of the bolus head. Dysphagia. Kang BS, Oh BM, Kim IS, Chung SG, Kim SJ, Han TR. doi: 10.1159/000021497. With the chin tucked, the anterior pharyngeal wall is pushed backward, thus narrowing the airway entrance. https://www.westlakedermatology.com/blog/kybella-vs-liposuction-vs-neck-lift To evaluate intra-rater reliability, an intraclass correlation coefficient (ICC) was used. Among these, the “chin-down” or “chin-tuck” posture has been recommended to various patients with the expectation that it can reduce the risk of laryngeal penetration or aspiration . Often the first half of the test will be normal but then the chin … Dysphagia. 2019 Dec;67(12):2643-2649. doi: 10.1111/jgs.16137. J Speech Lang Hear Res.

Additionally, vertical displacement was markedly increased in TUCK than DOWN. The maximal horizontal displacement of the hyoid bone was significantly less in TUCK (9.6 ± 3.0 mm) than in NEUT (12.6 ± 2.6 mm; p < 0.01) or DOWN (12.1 ± 3.0 mm; p < 0.01). When there were significant differences among the groups, a Bonferroni-corrected pairwise comparison was used for the post hoc analysis according to the homogeneity of the variables. On the other hand, DOWN had no significant effect on hyoid bone movement, which suggested that this comfortable posture did not compress or shorten these muscles. If you’re discontent with your double chin, Kybella® is one option that can help smoothen out your neck and sharpen your jawline. 2002;17:197–201. The study protocol was approved by the Institutional Review Board of our hospital, and all participants were informed of the potential experimental risks and signed an informed consent document before the study. According to a previous study concerning the mechanism of epiglottic tilt, a superior movement of the thyroid cartilage compresses the pre-epiglottic fat pad, which limits the downward movement of the epiglottic base during swallowing [19]. The purpose of the study was to investigate the influence of the chin-tuck maneuver on the movements of swallowing-related structures in healthy subjects and formulate standard instructions for the maneuver.

Videomanometric analysis of supraglottic swallow, effortful swallow, and chin tuck in healthy volunteers. From a neutral position, you try to bring your chin inwards and move it towards your neck. Dysphagia. Thus, in chin-down swallows, LVC occurred earlier and LVO occurred later. 2017 Mar 1;595(5):1793-1814. doi: 10.1113/JP272368. Timing of glottic closure during normal swallow. Successful Treatment with the Chin-down Maneuver of Dysphagia Secondary to Descending Necrotizing Mediastinitis: A Case Study. All digitized data were then filtered using a quintic spline algorithm. A total of 40 healthy volunteers (20 men and 20 women) swallowed 10 mL of diluted barium solution in a “normal and comfortable” position (NEUT), a comfortable chin-down position (DOWN), and a strict chin-tuck position (TUCK). Resting state anatomy and kinematic changes were analyzed and compared between pos-tures. Dysphagia. In TUCK, the submental muscle length is shorter than in NEUT. 2002;17:197–201. Austin: Pro-Ed; 1998. In NEUT, the epiglottic base initially moved upward and backward, then descended toward the anterior (Fig. Although patients are usually taught to “position the chin toward the chest and look down toward the knees,” instructions vary from clinic to clinic [1]. Dysphagia. FOIA The mean values of each kinematic parameter may be influenced by one swallow per posture and the individual variability in a single volunteer. The initial upward and backward movement may represent tongue base retraction in the pharyngeal phase of swallowing. Tuck the chin down, then pull the head back until it touches the wall. The video fluoroscopic recording was performed in the order of NEUT, DOWN, and then TUCK. During swallowing, the epiglottic base moves upward and backward, to the nasopharynx and posterior pharyngeal wall, respectively. All video clips were cropped from when the head of liquid reached the lower mandibular margin through the end of the liquid’s passage through the upper esophageal sphincter (UES). Resting state anatomy and kinematic changes were analyzed and compared between postures. Ann Rehabil Med. 2010;63:36–42. Bethesda, MD 20894, Copyright 2. Gerontology. Shanahan TK, Logemann JA, Rademaker AW, Pauloski BR, Kahrilas PJ. Shaker R, Dodds WJ, Dantas RO, Hogan WJ, Arndorfer RC. TUCK resulted in a reduced maximal horizontal velocity of the hyoid bone compared to NEUT (p = 0.001) and DOWN (p = 0.025) postures. Accessibility Considering that our study has broad age spectrum of subjects and swallowing physiology might differ along the age, we performed subgroup analysis in two age groups (patients aged <60 years, and aged ≥60 years). Bulow M, Olsson R, Ekberg O. Videomanometric analysis of supraglottic swallow, effortful swallow, and chin tuck in patients with pharyngeal dysfunction. Vandaele DJ, Perlman AL, Cassell MD.

Dysphagia The process and potential errors of the kinematic swallowing analysis. The hyoid movement trajectories during swallowing in a neutral (a), a comfortable chin-down (b), and a strict chin-tuck (c) posture are shown. COVID-19 is an emerging, rapidly evolving situation. Although there was an interval of just 1 month, the brightness characteristics of the images were slightly modified and the case names were changed prior to the second analysis. The distance of maximal horizontal excursion of the hyoid bone was significantly less in TUCK than in NEUT (p < 0.001) or DOWN (p < 0.001) postures. Byung-Mo Oh. Clark HM. Complete head rotation and chin tuck provide more overall benefit than partial maneuvers. Images were acquired on a mobile fluoroscopy system (Medix 3000, Hitachi, Japan), and two-dimensional (2D) digitization of the swallowing motion was performed with the same system, as described previously [10]. 1957;39(A):1280–8. The following points of interest in each video frame were analyzed using motion analysis software (Ariel Performance Analysis System; Ariel Dynamics, Inc., Trabuco Canyon, CA, USA). The laryngeal motions were decreased in both TUCK and DOWN compared to NEUT, although it was more remarkable in DOWN. This study was supported by a Grant from the Korean Geriatrics Society (2008). Gordon AM, Huxley AF, Julian FJ. The distance between the epiglottic base and the arytenoids in the lateral fluoroscopic projection, which represents the anteroposterior diameter of the laryngeal entrance, was narrower in TUCK than in NEUT (p = 0.001) or DOWN (p = 0.001) postures.

Progression - Chin tuck with band After the client has been performing the chin tuck exercise below for at least 2 weeks, a chin tuck with band resistance can be implemented. To measure the possible bias following flexion, each axis rotation angle (ARA) of the C2-C4 axis was analyzed against the true vertical axis in each posture. An asterisk represents…, The coordination of the kinematic analysis and the selected anatomical points, The pooled average trajectories of the hyoid bone and epiglottic base left column…, National Library of Medicine 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). The maximal horizontal displacement of the hyoid bone was significantly less in TUCK (9.6 ± 3.0 mm) than in NEUT (12.6 ± 2.6 mm; p < 0.01) or DOWN (12.1 ± 3.0 mm; p < 0.01). -. In contrast, DOWN increased the horizontal excursion of the epiglottic base and reduced movement of the vocal cords. Balou M, McCullough GH, Aduli F, Brown D, Stack BC Jr, Snoddy P, Guidry T.

A coin 24 mm in diameter was taped under the subject’s chin at the midline to serve as a reference ruler for radiographic magnifications. Ann Rehabil Med. Logemann JA. Compensatory approaches include food modification, postural changes, and compensatory maneuvers. Our results, which showed kinematic differences between DOWN and TUCK postures, suggest that we should emphasize patient education on correct postures. Comparing DOWN and TUCK, only TUCK induced significant changes in the airway entrance, hyoid movement, and epiglottic base retraction. Behavioral management for oropharyngeal dysphagia. 2003;12:400–15. Right column. [8] reported that the chin-tuck posture effectively decreases the distance of the anatomical structures, which causes shortening of the route necessary for laryngeal elevation. Shaw DW, Cook IJ, Gabb M, Holloway RH, Simula ME, Panagopoulos V, Dent J. Older group showed similar trends with results on Table 1 and 2, but statistical significance was compromised on all variables about the epiglottis and vertical displacement of the vocal cords. Steele CM, Hung D, Sejdic E, Chau T, Fraser S. Variability in execution of the chin-down maneuver by healthy adults. Here is my picture....maybe that will give you a better idea of what will work best for me. This can be explained by the tongue and submental muscles being compressed by the mandible in the TUCK posture. The chin-down posture has no remarkable effect, except on horizontal epiglottic movement. direction and a slight increase in the vertical Laryngoscope. Comparisons among head flexion only, neck flexion only, and head and neck flexion could provide more information about the effects of various postures. The study group consisted of 40 healthy volunteers (20 men and 20 women) ranging in age from 26 to 79 years (mean ± SD, 52.9 ± 17.9 years). (1994). The distance from the “zero” point to the anterior–inferior border of the second cervical vertebra was calculated to serve as a covariate of the vertical spatial relation, and the distance from the mental protuberance perpendicular to the y-axis in the resting position as that of the horizontal spatial relation in the pharynx. The minimum distance from the epiglottic base to the posterior pharyngeal wall was narrower in TUCK than in NEUT (p < 0.001) or DOWN (p < 0.001) postures. chin tuck head back head rotation head rotation plus supraglottic swallow chin tuck plus supraglottic swallow combined head rotation and chin tuck side lying * Logemann, J.A., Rademaker, A.W., Pauloski, B.R., Kahrilas, P.J. eCollection 2020.

Swallowing in TUCK generated a faster upward velocity of the epiglottic base (p = 0.016). When the extrinsic flexors are dominant the chin will translate forward instead of tucking in towards the neck as the head lifts. Increases vallecular space; narrows airway entrance b. Pushes epiglottis posteriorly into more protective position over airway c. Pushes tongue base backward toward pharyngeal wall d. Used if there is a delay in triggering the pharyngeal swallow (increased duration of stage transition); reduced posterior movement We stratified participants into three recruitment groups (10 subjects for those of 20–39 years old, 10 for those of 40–59 years old, and 20 for those older than 60 years old). 2020 Dec;44(6):493-501. doi: 10.5535/arm.20016. 1999 Spring;14(2):67-72. doi: 10.1007/PL00009589.

The most unique feature of the present study was that our method presented the locations of the major anatomical structures at each time point during swallowing in different head and neck postures. Recently, McCulloch [23] and Balou [25] examined manometric studies on both chin-down and chin-tuck postures, which revealed that a more tucked posture increased the duration of relaxation and decreased UES pressure. The purpose of the study was to investigate the influence of the chin-tuck maneuver on the movements of swallowing-related structures in healthy subjects and formulate standard instructions for the maneuver. The present study analyzed only one swallow per posture. Only TUCK showed a significantly shorter anteroposterior diameter of the laryngeal inlet (TUCK vs. NEUT, 14.0 ± 4.3 vs. 16.3 ± 5.0 mm) and the oropharynx (18.8 ± 3.1 vs. 20.5 ± 2.8 mm) at rest. Ohmae Y, Logemann JA, Kaiser P, Hanson DG, Kahrilas PJ. Traditionally, the “chin-down” or “chin-tuck” posture has been known to reduce the risk of aspiration by narrowing the airway entrance [7]. Each subject was instructed in the positions and allowed to practice the swallow in those positions prior to imaging. 2nd ed. 2010;119:369–76. The backward retraction and elevation of the epiglottic base is distinctively enhanced (f). Be sure to look for this pattern as the patient lowers the head back down too. Muscle operates with greatest contractile force when close to its resting length in an anatomical position [17]. This study substantiates the alleged effects of the chin-tuck maneuver through quantitative kinematic data such as maximal displacements, velocities, and tilt angles, which verify the difference between the chin-tuck and similar chin-down postures. Article  This site needs JavaScript to work properly. Although angles of anterior cervical flexion were comparable between DOWN (46.65 ± 9.69 degrees) and TUCK (43.27 ± 12.20), the chin-to-spine distance was significantly shorter in TUCK than in other positions. using a chin tuck with thin liquids to avoid nectar thick liquids. Evaluation and treatment of swallowing disorders. The authors have no conflicts to declare. ... With your palm against your forehead, now push your head down intending to bring your chin closer to your chest. 2001;16:190–5. (think about the movement as a book sliding back into the shelf) Whilst maintaining this chin tucked position, proceed to look up/down. Be sure to look for this pattern as the patient lowers the head back down too. In the determinations of the two raters, all measurements, except for the maximal horizontal velocity of the hyoid bone (0.717, 0.792), displayed almost perfect intra-rater reliability coefficients that ranged from 0.894 to 0.997. J Physiol. The in-depth analysis in this study revealed that the forward flexion of head and neck in the TUCK posture reduced the anteroposterior distance of the oropharynx as well as the laryngeal inlet at rest; whereas the DOWN posture had no effect on these distances. Careers. Am J Speech Lang Pathol. PubMed  The vertical and 2D excursion distance of TUCK of young age groups was also greater than in NEUT or DOWN, which is comparable with the results of whole group analysis. As a result, DOWN and TUCK postures combined both head and neck flexion. Please enable it to take advantage of the complete set of features! To calculate the coordinates for each point, we operationally defined the y-axis as a straight line connecting the anterior–inferior border of the fourth cervical vertebra (the origin) to the anterior–inferior border of the second cervical vertebra; the x-axis was a straight line perpendicular to the y-axis crossing the origin (Fig. Another explanation is that a reduced excursion distance can result from decreased resting muscle length. Displacement, angle, and velocity for the hyoid, epiglottis, and vocal cords were calculated and compared. -, Ertekin C, Keskin A, Kiylioglu N, Kirazli Y, On AY, Tarlaci S, Aydogdu I. Hold the neck retraction or chin tuck position for two to three (2-3) seconds, then release your neck back towards neutral position. Effects of Chin-Down Maneuver on Pharyngeal Pressure Generation According to Dysphagia and Viscosity. Extraction of average neck flexion angle during swallowing in neutral and chin-tuck positions. Otolaryngology Head and Neck The maximal angle of epiglottic rotation also increased from NEUT to DOWN and TUCK, but the trend was not significant.

Younger age group showed more definite differences on the maximal excursion of three anatomical structures. TUCK showed greater vertical and 2D excursions of the epiglottic base compared to NEUT (p = 0.004 and p < 0.001) and DOWN (p = 0.006 and p < 0.001) postures. ), held firmly under the chin to provide resistance to the motion of the chin pressing down against it as the head is nodded in a downward motion. Influence of the Chin-Down and Chin-Tuck Maneuver on the Swallowing Kinematics of Healthy Adults. Google Scholar. In contrast, DOWN increased the horizontal excursion of the epiglottic base and reduced movement of the vocal cords. Changes in the coordination between respiration and swallowing from suckling through weaning. Purpose This study examined the effects of chin-down swallowing on laryngeal vestibule closure. PubMed  The difference of hyoid horizontal excursion of three postures was similar with whole group analysis. (1994). Chin liposuction works by inserting a small tube, called a cannula, into the chin in different areas. For the sake of this tutorial, let’s say that our learner needs to use a chin tuck with thin liquids, as established by an instrumental swallow assessment. Partial chin tuck (chin down) decreases UES residual pressure. Molfenter SM, Steele CM. Matsuo K, Palmer JB (2008) Anatomy and physiology of feeding and swallowing: normal and abnormal. Part of Springer Nature. Effortful swallow enhances vertical hyolaryngeal movement and prolongs duration after maximal excursion. An, The pooled average trajectories of the hyoid bone and epiglottic base. The number of subjects needed ranged from 25 to 37 for all outcome measures to achieve a statistical power of ≥0.80 with an alpha level of p ≤ 0.05 based on power analyses. Epub 2020 Apr 8. See this image and copyright information in PMC. The reason why the maximal horizontal velocity of the hyoid bone was reduced significantly may be understood in this way. PubMed  This study aimed to investigate the influence of different chin-down postures on swallowing kinematics and to provide a more concrete rationale for the use of these maneuvers. The distance from the epiglottic base to the arytenoid, which represents the laryngeal inlet, is one of the most important markers for airway protection [15, 16]. Inter-rater tests of the measurements also showed comparable reliabilities from 0.748 to 0.995. The chin-down, head rotation, head tilting, supraglottic swallowing, and Mendelsohn’s maneuvers are examples of commonly used strategies [2, 3]. The results of the effectiveness of the chin-down and chin-tuck postures are controversial between studies. Pooled averages were calculated for the purpose of trajectory figure generation for the hyoid bone and epiglottic base. Changes in pharyngeal dimensions effected by chin tuck. Verbal feedback (“tuck your chin in” or “hold your head up”) is given to the subject when their head touches the examiner's left hand during the test. When we refer to their findings in light of the present study, TUCK resulted in no changes in total excursion, but the influence of horizontal (anterior) movement waned, which resulted in decreased UES pressure. The isokinetic portion is 30 repetitions of up and down head movement 3 times. Resting state anatomy and kinematic changes were analyze d and compared between pos-tures. [8] revealed that the chin-tuck posture decreased resting state distances from the hyoid bone to the larynx and mandible. The study group consisted of 40 healthy volunteers (20 men and 20 women) ranging in age from 26 to 79 years (mean ± SD, 52.9 ± 17.9 years). To reduce variability, volunteers in this study practiced a dry swallow three times in each posture and swallowed a barium bolus without radiation before capturing one swallow for image analysis.
