Left, Right, or Bilateral Thalamic Deep Brain Stimulation for Voice Tremor: A Prospective, Randomized, Double-Blinded Trial
In Brief
A clinical study evaluating Deep Brain Stimulation for Essential Voice Tremor and 5 related conditions. Completed, enrolled 6 participants across 1 site.
Detailed Summary
Deep Brain Stimulation (DBS) is the gold standard treatment for Essential Tremor (ET). ET is a movement disorder which causes the arms, feet, fingers, head or voice to involuntarily shake. The DBS surgical procedure involves implanting an electrode deep within the brain which blocks damaging signals that cause the tremor. Essential Voice Tremor (EVT) is the vocal manifestation of ET and a number of individuals have both ET and EVT, and when these patients are implanted for their ET, their EVT symptoms are often also mitigated. This study aims to quantify the effects of DBS on EVT by testing on these ET+EVT patients. In addition to this, we hope to determine which hemisphere of the brain is responsible for larynx control: left or right.

Interventions
* DBS System Medtronic * DBS programming settings will be set to maximally alleviate limb tremor, primary reason for referral * These settings will be used to evaluate effects of voice tremor as well
