Study Summary

This trial will investigate whether or not deep brain stimulation can help improve voice disorders in patients with dystonia or essential tremor.

Who is the study for?
This trial is for adults aged 18-80 with voice disorders due to dystonia or essential tremor, who are candidates for deep brain stimulation (DBS) surgery. Participants must be able to follow instructions, complete training, and give informed consent. They should not have obstructive venous anatomy, significant hearing loss, or inability to perform required tasks.Check my eligibility
What is being tested?
The study aims to understand how often voice disorders occur in patients with dystonia and essential tremor treated with DBS. It will explore the changes in brain imaging and activity related to voice dysfunction before and after the treatment.See study design
What are the potential side effects?
While specific side effects of DBS on voice functions aren't detailed here, common risks include speech problems, muscle stiffness or numbness around the implant site, headache, balance issues, mood changes.

Answered by AI

Do I qualify to be a participant in this trial?

"This clinical trial is administering the intervention to 120 patients suffering from tremor, aged 18-80. To be considered for inclusion in this study, applicants must meet the following conditions: have a definite diagnosis of essential tremor or dystonia; demonstrate refractory disease with regards to medication; pass neuropsychological evaluation administered by an accredited clinician; display cognitive aptitude that allows them to understand and complete test directions as well as provide informed consent. Individuals who fail preoperative task training or possess significant hearing loss are excluded from participation, as well those whose cortical venous anatomy might interfere with ECoG electrode placement (as seen on"
