Objective To quantify the effects of 2 swallowing maneuvers used in dysphagia rehabilitation—the Mendelsohn maneuver and effortful swallowing—on pharyngoesophageal function with novel, objective pressure-flow analysis. Study Design Evaluation of intervention effects in a healthy control cohort. Setting A pharyngoesophageal motility research laboratory in a tertiary education facility. Subjects Twelve young healthy subjects (9 women, 28.6 ± 7.9 years) from the general public, without swallowing…

Impact of Sensory Stimulation on Pharyngo-esophageal Swallowing Biomechanics in Adults with Dysphagia: A High-Resolution Manometry Study
TLDR
Sensory stimulation induced biomechanical changes to pharyngeal contraction vigor, UES relaxation time and extent of UES opening during swallowing in adults with dysphagia were investigated using pharyngo-esophageal high-resolution manometry.
Effect of Body Position on Pharyngeal Swallowing Pressures Using High-Resolution Manometry
TLDR
This study aims to identify positional adaptations of pharyngeal physiology by evaluating swallowing pressure patterns in a series of inverted body positions using high-resolution manometry to identify changes in pressure gradients when inverted, likely due to a combination of changes in pharygeal driving force and UES opening mechanisms.
High-resolution manometry: what about the pharynx?

    Current opinion in otolaryngology & head and neck surgery
  • 2018
TLDR
This review focuses on the measurement of pharyngeal luminal occlusive forces, intrabolus distension pressure, bolus presence and bolus flow timing as key features of phaya that require measurement and allow for derivation of the Swallow Risk Index.
Effect of Tongue-Hold Swallow on Pharyngeal Contractile Properties in Healthy Individuals
TLDR
Holding the tongue anteriorly during swallow requires significant biomechanical changes to pharyngeal contractile properties at the superior and middle pharygeal constrictor levels; thus, it may serve as a resistance exercise for the muscles that are involved in bolus propulsion.
The Mendelsohn Maneuver and its Effects on Swallowing: Kinematic Analysis in Three Dimensions Using Dynamic Area Detector CT
TLDR
The changes in the timing and magnitude of hyoid displacements and prolonged closure of the pharynx during swallowing suggest the utility of MM for improving the safety and efficiency of swallowing in selected cases.
A Systematic Review of the Physiological Effects of the Effortful Swallow Maneuver in Adults With Normal and Disordered Swallowing.
TLDR
Findings indicated that the effortful swallow generated greater pressures in the tongue-to-palate, pharynx, upper esophageal sphincter, and esophagal regions, which included increased pressures inThe biomechanical and functional effects of the effortfully swallow in adults with and without dysphagia were summarized.
Pharyngeal Manometry in Pediatric Dysphagia Assessment
TLDR
Reliable measures to capture swallowing pathophysiology and outcomes from therapeutic interventions are needed in the pediatric setting and the current best measures are presented are presented.
High-Resolution Pharyngeal Manometry and Impedance: Protocols and Metrics—Recommendations of a High-Resolution Pharyngeal Manometry International Working Group
TLDR
This work represents the first step in standardization of high-resolution pharyngeal manometry acquisition, measurement, and reporting and could potentially inform future proposals for an HRPM-based classification system specifically for pharynGEal swallowing disorders.

  • 2018
TLDR
This review revealed distinct swallowing impairments and increased pneumonia risks following esophagectomy, and found that evidence on the efficacy of therapeutic interventions was limited.
Flexible submental sensor patch with remote monitoring controls for management of oropharyngeal swallowing disorders
TLDR
A skin-mountable sensor patch that can fit on the curvature of the submental (under the chin) area noninvasively and provide simultaneous remote monitoring of muscle activity and laryngeal movement during swallowing tasks and maneuvers is presented.

Submental sEMG and hyoid movement during Mendelsohn maneuver, effortful swallow, and expiratory muscle strength training.
TLDR
Study results demonstrated differential effects of the 3 experimental tasks on the principles of task specificity and overload, which are important in the development of effective rehabilitative programs.
Comparison of effortful and noneffortful swallows in healthy middle-aged and older adults.
TLDR
Biomechanical and bolus flow aspects of swallowing changed when healthy individuals performed effortful swallows with 3-mL boluses, and several durational measures were significantly longer with the effortful swallow.
Tongue pressure and submental surface electromyography measures during noneffortful and effortful saliva swallows in healthy women.
TLDR
Despite the general age-related deterioration of the swallowing musculature due to the phenomenon of sarcopenia, older women can still produce noneffortful and effortful swallows with lingual pressure and submental surface electromyography amplitudes similar to younger women.
Videomanometric Analysis of Supraglottic Swallow, Effortful Swallow, and Chin Tuck in Patients with Pharyngeal Dysfunction
TLDR
The swallowing techniques did not seem to prevent the occurrence of retention or improve weak pharyngeal constrictor muscles in this group of patients with severe to moderate dysfunction.
Timing of Pharyngeal and Upper Esophageal Sphincter Pressures as a Function of Normal and Effortful Swallowing in Young Healthy Adults
TLDR
Results revealed that manometric timing measurements are consistent across trials, and offer insight as to the potential positive and negative influence of the effortful swallow on pharyngeal timing.
A method to objectively assess swallow function in adults with suspected aspiration.
TLDR
Pressure-flow variables derived from automated analysis of combined manometric/impedance measurements provide valuable diagnostic information and are a robust predictor of aspiration.
A Novel Method for the Nonradiological Assessment of Ineffective Swallowing
TLDR
Novel findings are presented in control subjects and dysphagic patients showing that combined manometry and impedance recordings can be objectively analyzed to derive pressure-flow variables that are altered in relation to the bolus residual and can be combined to predict ineffective pharyngeal swallowing.
Videomanometric Analysis of Supraglottic Swallow, Effortful Swallow, and Chin Tuck in Healthy Volunteers
TLDR
Simultaneous videoradiography and solid-state manometry was applied in eight healthy volunteers without swallowing problems and it was assumed dysphagic patients would need a substantial period of training to perform a technique efficiently.
