| Objective: This study investigated the effect of twang production on physiologic, acoustic, and perceived voice handicap measures in speakers with hypophonia. |
| Objective: Our goal was to determine whether percutaneous laryngeal collagen augmentation improves hypophonia in parkinsonian patients. |
| Symptoms such as shuffling gait, loss of dexterity, festination, freezing of gait, hypophonia and loss of articulation, and falls because of loss of postural reflexes. |
| It has significant relationship with bradykinesia and hypophonia. |
| Conclusions: Percutaneous laryngeal collagen augmentation is an effective treatment for parkinsonian hypophonia in a majority of patients. |
| It can include micrographia, hypomimia, hypophonia as well as decreased blink rate. |
