Swallowing Evaluation

Purpose: In this article we describe the mechanism of normal swallowing, the clinical or bedside evaluation, radiographic evaluation of swallowing disorders. The material is taken from selected references and information obtained from our experiences in the study of this area. The purpose of this article is to present this discussion in the hopes of generat­ing a new or in some cases a continued interest in the study of this disorder.

The Mean

Summary and Discussion: Subjects were used for establishing norms for labial strength. The group consisted of 114 NRSP subjects, all of whom were elementary school children in grades 3-6. The data of the 114 NRSP subjects shows the mean labial strength as being 4.45 lbs. There also appears to be some support for using the labial strength measurements as part of the diagnostic criteria for identifying the presence of reverse swallowing patterns (RSP). In addition, it is suggested that a measurement level well below the normative mean can be used successfully while a measurement of 4 lbs. and above could represent normal labial pressure. This procedure is strongly suggested in as much as most assessment presently utilized in determining the presence and/or absence of RSP have been essentially subjective observations. If the procedure mentioned herein is utilized, at least one objective measurement can be used along with the subjective observations. This writer feels that labial strength can be used along with the traditional observations for the successful diagnosis of RSP.

The aim of this study was to assess the physiology of normal swallowing using recent advances in real-time magnetic resonance imaging (MRI). Therefore ten young healthy subjects underwent real-time MRI and flexible endoscopic evaluations of swallowing (FEES) with thickened pineapple juice as oral contrast bolus. MRI movies were recorded in sagittal, coronal, and axial orientations during successive swallows at about 25 frames per second. Intermeasurement variation was analyzed and comparisons between real-time MRI and FEES were performed. Twelve distinct swallowing events could be quantified by real-time MRI (start time, end time, and duration). These included five valve functions: oro-velar opening, velo-pharyngeal closure, glottal closure, epiglottic retroflexion, and esophageal opening; three bolus transports: oro-velar transit, pharyngeal delay, pharyngeal transit; and four additional events: laryngeal ascent, laryngeal descent, vallecular, and piriform sinus filling and pharyngeal constriction. Repetitive measurements confirmed the general reliability of the MRI method with only two significant differences for the start times of the velo-pharyngeal closure (t(8)=-2.4,P≤0.046) and laryngeal ascent (t(8)=-2.6,P≤0.031). The duration of the velo-pharyngeal closure was significantly longer in real-time MRI compared to FEES (t(8)=-3.3,P≤0.011). Real-time MRI emerges as a simple, robust, and reliable tool for obtaining comprehensive functional and anatomical information about the swallowing process.

Tongue Thrust

The purpose of this article is to report on the use of a rather simple method of palatography to supplement clinical inspection in the evaluation of swallowing patterns. This method allows inspection of contact zones made by the tongue against the palatal and dental structures during deglutition. The procedures of direct palatography used in this study were simple, inexpensive, and graphically revealed differences between normal swallowing and tongue thrust swallowing patterns in a manner consistent with clinical evaluation expectancies. These data reveal that direct palatography can be used clinically to support the myo-functional clinician in establishing an accurate evaluation of tongue thrust. Direct palatography also constitutes a graphic record of contact zones between the tongue and the dental-palatal structures during swallowing. [article excerpts]

In order to support swallowing, the efficacy of functional electrical stimulation for different stimulation settings of the submental musculature has been investigated. The stimulation was administrated at rest and synchronously to voluntary initiated swallows. The onset of a swallow was detected in real-time by a combined electromyography/ bioimpedance measurement at the neck in order to trigger the stimulation. The amplitude and speed of larynx elevation caused by the FES has been assessed by the observed change in bioimpedance whereas a reduction of bioimpedance corresponds to an increase in larynx elevation. Study results from 40 healthy subjects revealed that 73% of the subjects achieved a larger and faster larynx elevation during swallowing with triggered FES and therefor a better protection of their airways. However, we also observed a decrease in larynx elevation compared to normal swallowing in 11 out of the 40 subjects what might not benefit from such a treatment. The largest improvement of larynx elevation and speed during swallowing could be achieved with three stimulation channels formed by four electrodes in the submental region.
