Summary
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).

| DEVICE | vibro-tactile stimulation (VTS) | To apply vibro-tactile stimulation, participants will use a wearable device. It contains two vibratory motors (Precision MicrodrivesTM, Model 307 - 100) that are low-voltage (\~1V), non-invasive and will be located approximately above the lateral portions of the thyroid cartilage. For this protocol, they vibrate at frequencies between 40 - 100 Hz (i.e., 100 times per second |
