The Biomechanical Characteristics of Swallowing in Tracheostomized Patients with Aspiration following Acquired Brain Injury: A Cross-Sectional Study.

In addition, in the patient group, VP maximal pressure ( r s = −0.439; p = 0.015), UES relaxation duration ( r s = −0.532; p = 0.002), and the subglottic pressure ( r s = −0.775; p < 0.001) were negatively correlated with the PAS score, while UES residual pressure ( r s = 0.807; p < 0.001) was positively correlated with the PAS score ( p < 0.05), the correlation between TB maximal pressure and PAS score ( r s = −0.315; p = 0.090) did not reach statistical significance.
