LARYNGEAL DYSTONIA

Laryngeal dystonia causes the vocal folds to spasm, leading to a strained or breathy voice. This study tests whether a non-invasive brain stimulation technique called rTMS can calm the overactive brain signals that cause these spasms. Twenty-five adults with laryngeal dystonia wi…

This early study tests whether a non-invasive brain stimulation technique called tDCS can improve voice quality in people with laryngeal dystonia (spasmodic dysphonia). Ten participants will receive active, sham, and no stimulation to compare effects. The goal is to see if target…

This study tests a brain-computer interface (BCI) that gives real-time feedback to help people with laryngeal dystonia control voice spasms. About 40 adults with a specific type of voice disorder will try this adaptive neurofeedback therapy. The goal is to reduce the number of vo…

This study looks at how a gentle vibration applied to the throat affects brain activity and voice in people with laryngeal dystonia, a condition that causes involuntary voice spasms. Researchers will use brain scans and voice recordings to understand why some people get relief fr…

This study looks at how deep brain stimulation (DBS) — a treatment already used for movement disorders — affects voice and speech in people with laryngeal dystonia or voice tremor. Researchers will record brain signals during surgery and measure voice changes afterward. The goal …

Researchers at Massachusetts Eye and Ear are studying 165 people with laryngeal dystonia or voice tremor, along with healthy volunteers, to better understand these voice disorders. Participants will undergo voice recordings, breathing tests, and imaging to identify distinct featu…

This study looks at how brain changes and genetic risk factors are linked in laryngeal dystonia, a voice disorder. Researchers will use brain imaging and DNA tests in up to 410 people, including patients, their relatives, and those with similar voice problems. The goal is to find…

This study uses brain scans (fMRI, MEG, EEG) and a numbing throat spray to understand what goes wrong in the brains of people with laryngeal dystonia or voice tremor. Researchers will compare brain activity between these groups and healthy volunteers. The goal is to find unique b…
