Research Abstract

The aim of this study was to develop a portable system to evaluate swallowing function noninvasively at bedside. Swallowing was objectively evaluated by measuring its dynamic state from simultaneous recordings of the laryngeal movement and electromyogram (EMG). The laryngeal movement was measured with a pulse transducer for fingertip-level pulse-wave measurements (Piezo-Electric Pulse Transducer) that was fixed to the neck under the right auricula at the same level with the thyroid cartilage. Superficial EMG of suprahyoid muscles was recorded with bipolar surface electrodes to monitor the muscle activities during the swallowing. Simultaneous recordings of the laryngeal movement, EMG, and VFG were performed.
To analyze how the physical properties of foods will influence swallowing easiness, swallow movements of six different concentrations of gelatin, agar, and starch were measured by this system.
In all the subjects, the laryngeal movement during swallowing showed a "W"-type waveform, which showed good intra-individual repeatability. The swallowed food was stopped for a moment on the epiglottis, as observed by VFG. This stop was also observed in the waveform of the laryngeal movement. The epiglottis, which was closing the trachea, returned to the original position at the end of swallowing, as can be observed by VFG and by a small peak in the waveform of the laryngeal movement. Thus, the swallowing period was divided in two : A (transit time from the base of the tongue to the epiglottis) and B (transit time from the epiglottis to the esophagus). The duration of A increased with the food concentration. However, there was no difference in the duration of B for neither food nor concentration.
The duration of bolus passage during swallowing could be measured without VFG, this portable system therefore proved useful to evaluate swallowing function at bedside.
