Study Summary
This trial is testing whether vibro-tactile stimulation can help improve the speech of people with laryngeal dystonia (a movement disorder that affects the muscles of the larynx).
Who is the study for?
This trial is for adults over 18 with a confirmed diagnosis of adductor or abductor spasmodic dysphonia (a voice disorder) for at least 6 months. It's not suitable for those with cognitive issues, regular benzodiazepine users, pregnant individuals, non-English speakers, or people with certain neurological conditions affecting speech.Check my eligibility
What is being tested?
The study tests whether vibro-tactile stimulation (VTS), a non-invasive treatment that uses vibrations on the throat area, can improve speech in patients suffering from laryngeal dystonia or spasmodic dysphonia.See study design
What are the potential side effects?
Since VTS is non-invasive and doesn't involve drugs, significant side effects are not expected. However, participants may experience discomfort or mild irritation where the device touches the skin.

4Treatment groups
Experimental Treatment
Group I: Low dose / speech activated VTSExperimental Treatment1 Intervention
Low dose refers to receiving VTS 5 times/week for 20 minutes each; VTS during connected speech
Group II: Low dose / continuous VTSExperimental Treatment1 Intervention
Low dose refers to receiving VTS 5 times/week for 20 minutes each; non-task-specific, constant stimulation during non-speech
Group III: High dose / speech activated VTSExperimental Treatment1 Intervention
High dose refers to receiving VTS 7 times/week for 20 minutes each; VTS during connected speech
Group IV: High dose / continuous VTSExperimental Treatment1 Intervention
High dose refers to receiving VTS 7 times/week for 20 minutes each; non-task-specific, constant stimulation during non-speech
