Summary

This trial will enroll people with Adductor Laryngeal Dystonia (ADLD) to study the efficacy of Deep Brain Stimulation (DBS) in treating the condition. DBS is a neurosurgical procedure used to treat tremors and dystonia. Before surgery, participants will undergo specialized testing to study the movement of the vocal cords, as well as functional MRI. In the operating room, researchers will examine brain waves to better understand how faulty brain firing patterns lead to dystonia. After surgery, participants will repeat speech testing and vocal cord imaging as well as MRI.

Eligible Conditions
  • Spasmodic Dysphonia
  • Adductor Spastic Dysphonia

Trial Design

1Treatment groups
Experimental Treatment
Group I: Deep Brain StimulationExperimental Treatment1 Intervention
Voice outcomes and Magnetic resonance imaging will be compared pre- and post-DBS (Deep brain stimulation) in patients with laryngeal dystonia and adductor laryngeal dystonia. The evaluators will be masked for analyzing the voice outcomes pre-and post-DBS
