The tongue-hold maneuver is an exercise to strengthen the pharyngeal constrictor muscle during swallowing. Although the mechanism of this exercise was confirmed in patients with oral cancer, conclusions based on shortand long-term studies of other diseases or healthy people are unclear. No cross-sectional studies have been conducted on how far the tongue is protruded during a tongue-hold maneuver. The purpose of this study was to investigate the degree of tongue protrusion during a tongue-hold maneuver over the maximum tongue protrusion length and identify the suprahyoid muscle activation during this exercise. Eleven healthy adults (9 females, 2 males) participated in this study. The results showed that there was a significant difference between the tongue protrusion length during a tongue-hold maneuver and maximum tongue-protrusion length (p= 0.003). During the tongue-hold maneuver, the activities of the suprahyoid muscle were significantly higher than that during normal swallowing and significantly lower than that during effortful swallow. Although there was no significant difference between the activity of the suprahyoid muscle during the original tongue-hold maneuver and tongue-hold maneuver with 1/3rdtongueprotrusionor2/3rdtongueprotrusion(p= 0.156, 1.000, respectively), the difference in muscle activity was -17% and 6.7%, respectively. In order to achieve the therapeutic goal of a tongue-hold maneuver accurately, it will be necessary to clarify whether subjects protrude their tongues accurately according to the clinician¡¯s instructions.
