Although effortful swallow and the Mendelsohn maneuver are commonly used in dysphagia rehabilitation, little is known about their effects on tongue-palate pressure production. The purpose of this study was to investigate the effects of effortful swallow and the Mendelsohn maneuver on tongue pressure production. Fourteen healthy volunteers (10 men, 4 women; age range = 21-41 years) participated. Tongue pressures during dry swallow, water swallow, effortful swallow, and the Mendelsohn maneuver were measured using a sensor sheet system with five measurement points on the hard palate. Sequential order, duration, maximal magnitude, and the integrated value of tongue pressure at each measurement point were compared among the four tasks. Onset of tongue pressure at the posterior-circumferential parts occurred first in the Mendelsohn maneuver; that at the anterior-median part was earlier than at other parts in the effortful swallow. At all measurement points, tongue pressure duration was significantly longer in the Mendelsohn maneuver than in other tasks. Effortful swallow was most effective in increasing tongue pressure. The integrated value of tongue pressure at the posterior-circumferential parts in the Mendelsohn maneuver and at the median parts in the effortful swallow showed a tendency to increase. These results suggest that tongue pressure increases along a wide part of the hard palate in effortful swallow because the anchor of tongue movement is emphasized at the anterior part of the hard palate. The Mendelsohn maneuver provides prolonged and accentuated tongue-palate contact at the posterior-circumferential parts, which might be important for hyoid-laryngeal elevation during swallowing.


Effects of the Mendelsohn Maneuver on Extent of Hyoid Movement and UES Opening Post-Stroke

Dysphagia. 2013 Mar 14.


The Mendelsohn maneuver, voluntary prolongation of laryngeal elevation during the swallow, has been widely used as a compensatory strategy to improve upper esophageal sphincter (UES) opening and bolus flow. Recent research suggests that when used as a rehabilitative exercise, it significantly improves duration of hyoid movement and positively impacts duration of UES opening (DOUESO). The data presented here were derived from that same prospective crossover study of 18 participants with dysphagia post-stroke evaluated with videofluoroscopy after treatment using the Mendelsohn maneuver versus no treatment. Results demonstrate gains in the extent of hyoid movement and UES opening and improvements in coordination of structural movements with each other as well as with bolus flow.

Abstract —

Evidence-based practice (EBP) involves the integration of three essential principles: (1) the current best available research, (2) the clinician’s experience and expertise, and (3) the patient’s values and preferences. This report is the last in a series that presents the culmination of a collaborative effort between the American Speech-Language-Hearing Association and the Department of Veterans Affairs to examine the state of the evidence on seven behavioral swallowing interventions. This article addresses how speech-language pathologists treating individuals with oropharyngeal dysphagia can incorporate EBP into their clinical decision-making process. A fictitious patient scenario is presented and discussed as an example of the clinical application of the findings from the three systematic reviews in this series on evidence for the use of behavioral swallowing interventions. Also, recommendations for researchers studying dysphagia treatment are discussed, with the overall goal of facilitating the generation of a stronger evidence base for clinicians.

Abstract —

This evidence-based systematic review (EBSR) is part of a series of reviews examining the state of the research regarding behavioral interventions for dysphagia. This EBSR focuses primarily on dysphagia secondary to neurological disorders (e.g., brain injury, stroke, Parkinson’s disease, and dementia). The seven behavioral treatments investigated were three postural interventions (side lying, chin tuck, and head rotation) and four swallowing maneuvers (effortful swallow, Mendelsohn, supraglottic swallow, and super-supraglottic swallow). We systematically searched the dysphagia literature from March 2007 to April 2008 using 14 electronic databases. Seven studies met the inclusion and exclusion criteria and were evaluated for methodological quality and stage of research. Of the included studies, only two were judged to be efficacy research; the remaining five were considered exploratory. Methodological quality of studies ranged from one to seven out of eight possible quality markers. Five of seven treatment interventions were addressed by at least one study. No studies were found to address the effortful swallow or the super-supraglottic swallow. Currently, limited evidence from seven studies shows the potential effects of dysphagia behavioral interventions for select groups of individuals with neurologically induced dysphagia. Further research is needed to evaluate the effectiveness of these and the remaining interventions with various populations with neurological disorders.

Abstract —

This article is the second in a series of evidence-based systematic reviews. Data reported cover the impact of dysphagia behavioral interventions on swallow physiology in healthy adults. The behavioral treatments investigated were three postural interventions-side lying, chin tuck, and head rotation-and four swallowing maneuvers-effortful swallow, the Mendelsohn maneuver, supraglottic swallow, and super-supraglottic swallow. A systematic search of the dysphagia litera-ture was conducted in 14 electronic databases. Seventeen studies meeting the inclusion criteria were evaluated for methodological quality with the American Speech-Language-Hearing Association’s levels-of-evidence scheme and were characterized by research stage (i.e., exploratory, efficacy, effectiveness, cost-benefit/public policy research). Effect sizes were calculated when possible. All studies were exploratory research ranging from two to five of seven possible quality markers. The majority of studies (8 of 17) investigated effortful swallow. Three studies examined the Mendelsohn maneuver, chin tuck, supraglottic swallow, and super-supraglottic swallow and two studies addressed head rotation. No study addressed side lying. For nondisordered populations, the existing evidence demonstrates differential effects of postural changes and maneuvers on swallowing physiology. Some effects reinforced existing recommendations for the applications of the interventions, while others suggested new ways that the treatments may impact swallow function. Avenues for future research are suggested.

Effects of Mendelsohn maneuver on measures of swallowing duration post stroke

PURPOSE: The purpose of this pilot study was to determine whether intensive use of the Mendelsohn maneuver in patients post stroke could alter swallow physiology when used as a rehabilitative exercise. METHOD: Eighteen outpatients between 6 weeks and 22 months post stroke were enrolled in this prospective study using a crossover design to compare 2 weeks of treatment with 2 weeks of no treatment. Each participant received an initial videofluoroscopic swallow study (VFSS) and an additional VFSS at the end of each week for 1 month for a total of 5 studies. During treatment weeks, participants received 2 treatment sessions per day performing Mendelsohn maneuvers with surface electromyography for biofeedback. Measures of swallowing duration, penetration/aspiration, residue, and dysphagia severity were analyzed from VFSS to compare treatment and no-treatment weeks. RESULTS: Significant changes occurred for measures of the duration of superior and anterior hyoid movement after 2 weeks of treatment. Improvements were observed for duration of opening of the upper esophageal sphincter (UES), but results were not statistically significant. Measures of penetration/aspiration, residue, and dysphagia severity improved throughout the study, but no differences were observed between treatment and no-treatment weeks. CONCLUSIONS: Intensive use of the Mendselsohn maneuver in isolation altered duration of hyoid movement and UES opening in this exploratory study. Results can guide future research toward improved selection criteria and exploration of outcomes. Larger numbers of participants and variations in treatment duration and intensity will be necessary to determine the true clinical value of this treatment.
