Comparing Two Deep Brain Stimulation Leads to One in Refractory Tremor.

This article aims to report a double-blind assessment of five patients with a second DBS lead for refractory tremor. Tremor was assessed by two blinded movement disorder specialists using a videotaped tremor rating scale (TRS) evaluation of each patient in four conditions: both leads OFF, Vim ON/2nd lead OFF, Vim OFF/2nd lead ON, and both leads ON. Paired t-test was used to determine if double stimulation was different than stimulation of Vim alone or than stimulation of the 2nd lead alone. Each hypothesis was tested with the total TRS as well as the contralateral upper limb score and the contralateral hemibody score. Tremor was secondary to multiple sclerosis in two patients and to essential tremor in three. The second lead was in the ventralis oralis anterior nucleus of the thalamus in t…
