✦ Synopsis

We previously developed a method of tremor quantification using long-term electromyography registration of antagonistic forearm muscles that is reliable, sensitive, and specific for pathologic tremors. The present study demonstrates that tremor occurrence as measured by this method correlates well with clinical parameters of tremor in idiopathic Parkinson's disease (PD) and essential tremor (ET) (subscores of the Unified Parkinson's Disease Rating Scale for PD, tremor rating according to Bain et al. for ET). We conclude that the method is a valid and objective means of tremor quantification in PD and ET.

## Abstract Our objective was to investigate the long‐term safety and efficacy of unilateral deep brain stimulation (DBS) of the VIM nucleus of the thalamus in essential tremor. Forty‐nine patients were evaluated for DBS between December 1993 and March 1998. Tremor was assessed by a clinical rating
