Deep Brain Stimulation for Thalamic Pain Syndrome
In Brief
A clinical study evaluating Deep Brain Stimulation for Thalamic Pain Syndrome for Chronic Pain. Completed, enrolled 10 participants across 1 site.
Detailed Summary
The purpose of this study is to determine the safety and efficacy of Deep Brian Stimulation (DBS) of the ventral capsular/ventral striatal as a treatment for patients with Thalamic Pain Syndrome (TPS). The central hypothesis to be tested in this investigation is that VC/VS stimulation will modulate the affective component of TPS and, consequently, improve pain related disability.
Study Details
Timeline
Interventions
Patients will be randomized in a 1:1 ratio to one of two groups: the Treatment Group (active stimulation and programmed to the settings found to be optimal during the titration phase) and the Control Group (sham stimulation - IPG is set to ON but the voltage is set to 0V). In order to prevent too many patients from being randomized to ON or to sham early in the study, we will use, for the first 4 patients, randomization blocks of four or six. In this fashion, the first four consecutive patients will have two patients randomized to the Treatment Group and two patients in the Control Group. In the same fashion, the final six patients will have three patients randomized to the treatment group and three patients to the control group.
