The general aim of the research is to provide scientific evidence that vibro-tactile stimulation (VTS) represents a non-invasive form of neuromodulation that can induce measurable improvements in the speech of patients with laryngeal dystonia (LD) - also called spasmodic dysphonia (SD).
Inclusion: 18 years of age or older; Confirmed diagnosis of adductor or abductor LD for a minimum of 6 months.
Exclusion: Cognitive impairment: score < 27 on the Mini-mental State Examination (MMSE); Identify with a neurological or musculoskeletal impairment affecting speech motor function. These impairments may include a form of: Dyskinesia, Dystonia other than LD, Essential Tremor, Huntington's Disease, Multiple System Atrophy, Muscle Tension Dysphonia, Parkinsonism, Progressive Supranuclear Palsy, Spasticity, Intracranial Neoplasm (brain tumor), Spinal Neoplasm, Cerebrovascular Accident (Stroke), Mild Traumatic Brain Injury, Intracranial Hemorrhage, Multiple Sclerosis; Regular intake of benzodiazepines; Non-English speaker. We will not enroll people who cannot speak English, because the voice assessment procedures (Test sentences, CAPE_V clinical rating) have only been validated for English speakers at this point; Pregnant people. We will not enroll pregnant people as the device used in this study is investigational.
