ClinConnect Summary

This study is to evaluate the feasibility, reliability, and clinical effects of Non-invasive vibrotactile stimulation (VTS) on basic tasks of motor control and on the motor symptoms of patients with movement disorders. VTS Settings will include continuous stimulation, intermittent stimulation during walking, and sham stimulation.

The investigators will recruit 30 patients with PD who are between the ages of 18-80 years old and independently living in the community. The investigators will additionally recruit up to 5 patients with ET and up to 5 patients with dystonia.

• • For patients with ET, they will have a score of at least 2 on items 5 and 6 of the Fahn-Tolosa-Marin (FTM) Tremor Rating Scale.
• • For patients with dystonia, they will have abnormal dystonic postures of the head and not isolated head tremor
• Exclusion Criteria:
