## Abstract The role of subthalamic nucleus (STN) deep brain stimulation (DBS) is well established in Parkinson's disease, but experience with STN DBS in other movement disorders is limited. We report on a patient with medically refractory cervical dystonia and essential tremor resulting in dystoni

Abstract
To evaluate the posterior subthalamic area (PSA) as a target for deep brain stimulation (DBS) in the treatment of essential tremor (ET). The ventral intermediate nucleus of the thalamus is the traditional target for DBS in the treatment of ET. Recent studies have presented beneficial effects of DBS in the PSA in the treatment of tremor. Twentyβone patients with ET were included in this study. All patients were evaluated before and 1 year after surgery, on and off stimulation, using the essential tremor rating scale (ETRS). A marked microlesional effect was noticed in 83%, in some cases obviating the need for electrical stimulation for many months. The total ETRS was reduced from 46.2 at baseline to 18.7 (60%). Item 5/6 (tremor of the upper extremity) was improved from 6.2 to 0.3 (95%), and items 11 to 14 (hand function) from 9.7 to 1.3 (87%) concerning the contralateral hand. Activities of daily living were improved by 66%. No severe complication occurred. Eight patients presented a postoperative mild dysphasia that regressed within days to weeks. DBS in the PSA resulted in a marked reduction of tremor. Β© 2010 Movement Disorder Society

OBJECTIVE: To compare outcome in Essential Tremor (ET) patients who have undergone either thalamotomy or Deep Brain Stimulation (DBS) of the thalamus. BACKGROUND: Although both thalamotomy and thalamic DBS are effective surgical treatments of tremor, it is not known if one procedure is superior to
## Abstract Deep brain stimulation (DBS) of the ventral intermediate nucleus of the thalamus for essential tremor is sometimes limited by side effects. The mechanisms by which DBS alleviates tremor or causes side effects are unclear; thus, it is difficult to select stimulus parameters that maximize
## Abstract Our objective was to investigate the longβterm safety and efficacy of unilateral deep brain stimulation (DBS) of the VIM nucleus of the thalamus in essential tremor. Fortyβnine patients were evaluated for DBS between December 1993 and March 1998. Tremor was assessed by a clinical rating
