Directional Versus Nondirectional Deep Brain Stimulation of the VIM Thalamic Nucleus for Essential Tremor: Assessment of Therapeutic Window, Speech, Gait and Balance

This will be a single center (OHSU) proof of concept trial to demonstrate that directional deep brain stimulation (DBS) creates a larger therapeutic window for the treatment of essential tremor (ET), effectively treats ET, and minimizes effects on speech, gait and balance compared to nondirectional DBS.

Inclusion: A tremor syndrome of bilateral upper limb action tremor with at least 3 years' duration.

Exclusion: Patients who have decided not to receive DBS for control of their medication-refractory essential tremor; Prior history of deep brain stimulation; Prior history of thalamotomy; Patients with secondary tremor (ie not Essential Tremor), such as side effects from medications, secondary to another identified neurologic disease (eg multiple sclerosis, -----Parkinson's disease, dystonia); Patients with cardiac pacemakers, defibrillators, or neurostimulators; Subjects with other type of neurological disease or injury; A history or signs of dystonia, ataxia or parkinsonism; Task specific tremor; Orthostatic tremor; Patients who require MRI, ECT, rTMS, or diathermy.
