ABSTRACT

The purpose of this study was to investigate the standardization values of pressure for the chin-tuck and the jaw-opening using laryngeal elevation strengthening device. One hundred thirty-seven healthy adults (20s~≥80s) without neurological disease participated in this study. All subjects were measured by laryngeal elevation strengthening device during the chin-tuck and the jaw-opening. The measurement was performed three times for each task, and the order of the chin-tuck and jaw-opening was balanced to eliminate the order effect. The value calculated the peak pressure and the mean pressure. Statistical analysis was performed using independent t test and Pearson's correlation analysis. As a result, there was no significant difference between age and gender on the peak and mean values of the chin-tuck (p>.05). The peak and average values of the the jaw-opening pressure were significantly higher in males than females (p<.05). There was a significant negative correlation between age, the chin-tuck and the jaw-opening pressure. (p<.05). There was a significant positive correlation between the pressure of the chin-tuck and the jaw-opening. The reference values of chin-tuck and jaw-opening were found in healthy adults. These results can be helpful for efficient evaluation and training when conducting chin-tuck and jaw-opening exercises using the laryngeal elevation strengthening device in the clinic.
