This study aims to investigate the movements of hyolaryngeal structures during the surface electrical stimulation of suprahyoid muscles and to compare these with movements during liquid swallowing.Abstract:
Objective. This study aims to investigate the movements of hyolaryngeal structures during the surface electrical stimulation of suprahyoid muscles and to compare these with movements during liquid swallowing.
Materials and methods. Twelve volunteers without dysphagia participated in this study. Volunteers swallowed 5 mL of diluted barium liquid, which was recorded videofluoroscopically. They then received surface electrical stimulation at midpoints between the chin and the bilateral edges of the hyoid, and movements were again recorded. Two-dimensional motion analysis was performed and displacements of the hyoid and of subglottic air-column and epiglottic rotations were calculated. Movements caused by surface stimulation were compared to those during liquid swallowing.
Results. Elevation and anterior excursion of the hyoid by electrical stimulation were 66.8% and 45.2% of those during liquid swallowing, respectively, and rotation of the epiglottis by electrical stimulation was 24.0% of that during liquid swallowing. Elevation and anterior excursion of the subglottic air column during liquid swallowing were 24.1 mm and 4.6 mm, respectively, compared with 9.6 mm and 1.9 mm during electrical stimulation. All the movements during electrical stimulation were significantly smaller than those that occurred during liquid swallowing (p < 0.05). Trajectories of the hyoid and larynx during electrical stimulation were smaller than but similar to those that occurred during liquid swallowing.
Conclusion. This study suggests that surface electrical stimulation of suprahyoid muscles causes the elevation and anterior excursion of hyolaryngeal structures, as is observed during normal physiologic swallowing, although the movements involved were smaller. Further studies are required to determine the effect of synchronized electrical stimulation on dysphagia patients with reduced laryngeal elevation to allow the development of a swallow-assisting neural orthosis.read more

TL;DR: Both IEMT and NMES were associated with improvement in pharyngeal swallowing security signs at the end of the intervention, but the effect did not persist at 3-month follow-up and no differences in respiratory complications were detected between treatment groups and controls.

TL;DR: The functions of the infrahyoids muscles are also as important as that of the suprahyoid muscles for prolonged laryngeal elevation and UES opening and kinematic analysis of videofluoroscopic swallowing study (VFSS) and HRM studies could reflect results of needle EMG study and replace EMg study.

Electrical Stimulation of the Suprahyoid Muscles in Brain-injured Patients with Dysphagia: A Pilot Study
TL;DR: Although repetitive neuromuscular electrical stimulation of the suprahyoid muscles did not further improve the swallowing function of dysphagia patients with reduced laryngeal elevation, more patients in the ESSM group showed improvement in the ASHA level than those in the CDM group.

TL;DR: The responsibility of the clinical neurologist and neurophysiologist in the care for the dysphagic patients is twofold: to be more acquainted with the physiology of swallowing and its disorders, and to evaluate the dysphagia problems objectively using practical electromyography methods for the patients' management.

TL;DR: Stimulation may have acted to resist patients’ hyoid elevation during swallowing by lowering the hyoid bone and/or larynx when applied at rest and increased aspiration, penetration, or pharyngeal pooling during swallowing.

TL;DR: Findings indicate a tightly organized neural program for some pharyngeal swallow events with systematic variability with volume in other pharynGEal events, possibly modulated by afferent input from the periphery.

TL;DR: It is suggested that surface electrical stimulation will reduce elevation during swallowing therapy for dysphagia and be judged less safe than nonstimulated swallows using the National Institutes of Health-Swallowing Safety Scale.
