Comparing two botox injection methods for vocal tremor
Part of Ear, nose & throat clinical trials.
This study compares two ways of giving botox injections to treat vocal tremor (shaky voice). The goal is to see which method works better for reducing tremor and improving voice quality.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have essential voice tremor, which causes your voice to shake or tremble.
- You have been seen by a throat specialist (laryngologist) and a speech-language pathologist who confirmed the diagnosis.
- You are able to answer questionnaires in English.
- You do not have significant trouble swallowing (dysphagia) right now.
- You are not pregnant and have no known allergy to botox.

Other trials that look related to this one.
This study tests botulinum toxin (a medication that relaxes muscles) to treat various involuntary movements like tremors, muscle spasms, or uncontrolled facial movements. The goal is to see if this treatment can reduce your symptoms and improve your quality of life.
This trial studies a brain stimulation approach for a specific voice disorder that can include tremor. It aims to better understand how well the treatment works and how to use it more effectively while carefully checking safety with awake procedures.
This study tests whether injections of botulinum toxin (Dysport) can help people whose hand tremor only happens when they try to do specific tasks, like pouring a drink or eating. If you qualify, you would receive injections and be monitored to see if your tremor improves.
This trial studies deep brain stimulation (a surgically placed device that sends electrical signals) to reduce voice tremor or laryngeal dystonia. You may be considered if your symptoms are persistent despite medication and you can complete the study tasks and pre-surgery testing.
This early study uses brain and voice-related testing to better understand what is happening in the brain in people with laryngeal dystonia or voice tremor. The results may help scientists learn more about these conditions and how they differ from healthy voices.
This trial tests an investigational botulinum toxin injection (AGN-151607-DP) to reduce shaking in the hands and arms caused by essential tremor. It is for adults who have been diagnosed with this condition and who do not have certain nerve or muscle disorders.
