Abstract:
Objective:To investigate the effect of a Passy-Muir speaking valve (PMV) on the biomechanics of swallowing and on aspiration among persons tracheotomized after brain damage.
Methods:Twenty tracheotomized patients with aspiration after brain injury were selected and randomly divided into a non-PMV intervention group and a PMV intervention group, each of 10. Both groups were given routine swallowing training, while the PMV intervention group was additionally provided with a PMV and trained to use it. The treatment ended when the tracheal tube was removed or after 2 weeks. High-resolution manometry and videofluoroscopy were used to evaluate the maximum pressure in the velopharynx (VP-Max), the maximum post-deglutitive upper esophageal sphincter (UES) pressure (UES-Max) and Rosenbek penetration aspiration (PAS) scores for both groups before and after the treatment.
Results:Before the treatment there was no significant difference between the two groups in terms of average VP-Max, UES-Max or PAS score. After the treatment, the average VP-Max and UES-Max had increased significantly in both groups, and the average PAS score of the PMV intervention group had decreased significantly. There was a significant positive correlation between the increases in VP-Max and the decrease in PAS scores.
Conclusion:Inserting a PMV can improve velopharynx contraction and post-deglutitive UES among persons tracheotomized after a brain injury. The increase in maximum velopharynx pressure is positively correlated with decreases in aspiration.
