Effect of Tongue-Hold Swallow on Laryngeal Elevation During Swallowing in Healthy Older Men

The maximum tongue pressure and laryngeal elevation distance in the saliva/ES condition were greater after the training. THS and MM showed similar levels of muscle activity in the submental muscles but not in the thyrohyoid muscle region. Therefore, the combination of THS with other training is recommended in strengthening the laryngeal elevation. THS may contribute not only to an increase of the posterior pharyngeal wall constriction and tongue retraction but also to an enhancement of the laryngeal elevation.
