Objective To investigate the effect of a Passy-Muir speaking valve (PMV) on biomechanics swallowing and aspiration among persons tracheotomized after brain damage.

Methods Twenty patients with injury were selected randomly divided into non-PMV intervention group PMV group, each 10. Both groups given routine training, while was additionally provided trained to use it. The treatment ended when tracheal tube removed or 2 weeks. High-resolution manometry videofluoroscopy used evaluate maximum pressure in velopharynx (VP-Max), post-deglutitive upper esophageal sphincter (UES) (UES-Max) Rosenbek penetration (PAS) scores for both before treatment.

Results Before there no significant difference between two terms average VP-Max, UES-Max PAS score. After treatment, VP-Max had increased significantly groups, score decreased significantly. There positive correlation increases decrease scores.

Conclusion Inserting can improve contraction UES injury. increase is positively correlated decreases aspiration.
