Trial Design

1Treatment groups
Experimental Treatment
Group I: Patients with Essential TremorExperimental Treatment3 Interventions
Patients with chronically implanted DBS devices for ET who experience progressive worsening of tremor symptoms over time. The DBS implantable pulse generator (IPG) will be loaded with a temporary custom firmware to allow implementation of active biphasic pulse stimulation. The following random conditions will be applied: (1) Home Settings; (2) VIN Biphasic; (3) Stimulator Off. A 30-minute washout period will be applied between each of the random conditions. Therefore, each patient will serve as their own control.
