Abstract
Background
A rise in tongue pressure coincides with an increase in the suprahyoid muscles activity.
Objectives
The aim was to investigate the effects of holding a weighted plastic bottle on tongue pressure and the suprahyoid muscles activity.
Methods
Eighteen participants (8 men and 10 women; mean age 42 ± 16 years) participated in this study. All participants had no history of speech, language, hearing, or swallowing disorders and no tooth loss, and they did not require dentures. Healthy participants held gauzes connected with a plastic bottle with increasing resistive loads of 0 g, 250 g, 500 g, and 750 g, between their palate and tongue. The maximum tongue pressure and average tongue pressure were measured during a 5-second hold. The average tongue pressure was defined as the mean tongue-pressure data in each task. The suprahyoid muscles activity was measured using the electromyogram (EMG). The root mean square of the EMG signals measured while lifting different loads and while performing the head lifting exercises were compared. All variables were examined using the Friedman's test and Wilcoxon signed-rank test.
Results
The maximum tongue pressure (p < .05) and average tongue pressure values (p < .05) increased gradually in the anterior–median region with increasing resistive loads, and the root mean square amplitudes for 250 g, 500 g, and 750 g were not significant compared to head lifting exercises.
Conclusion
These results indicated that Plastic bottle holding could be a potential strength-training tool for the tongue and the suprahyoid muscles.
