Study brain and voice patterns in laryngeal dystonia
Part of Brain & nervous system, Ear, nose & throat, Lungs & breathing clinical trials.
This study looks at how the brain and voice system work in people with laryngeal dystonia or voice tremor, and compares them with healthy volunteers. The goal is to better describe different “types” (phenotypes) so future care can be more targeted.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re 18 to 80 years old and can speak and understand English
- You’re right-handed and have normal thinking/memory (cognitive status)
- You either have laryngeal dystonia or voice tremor, or you are a healthy control without related problems
- If you’re treated with botulinum toxin (for example, Botox) for symptoms, you must be fully symptomatic and at least 3 months after your last injection
- You can consent for yourself, and you are not pregnant or breastfeeding during MRI
- You must be able to safely complete MRI (for example, no non-removable metal/ferromagnetic implants or certain tattoos)

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 study looks at how genetics and brain patterns are connected to laryngeal dystonia and voice tremor, including people with certain types of voice disorders. You may be asked to do imaging and voice-related assessments to help researchers understand what’s causing these symptoms.
This study tests how a brain–computer interface reads brain signals to understand and possibly support people with a specific voice condition called adductor laryngeal dystonia. It also compares results with healthy people to help researchers see how brain activity differs during voice tasks.
This trial uses brain scans to understand how brain networks work in people with focal dystonia, and to compare with family members and healthy volunteers. It may help researchers better understand what goes wrong in the brain and guide future treatments.
This study tests whether a noninvasive brain stimulation treatment (referred to as neuromodulation, such as rTMS) can improve symptoms of laryngeal dystonia. It’s meant to see if stimulating certain brain areas can reduce how severely your voice/throat problem affects you.
This study tests whether a gentle brain stimulation technique called tDCS can help improve voice control in people with laryngeal dystonia. It aims to find a new way to reduce muscle spasms in the voice box.
