A Randomized Trial of Focused Ultrasound Thalamotomy for Essential Tremor

Uncontrolled  pilot  studies  have  suggested  the  efficacy  of  focused  ultrasound  thalamotomy with magnetic resonance imaging (MRI) guidance for the treatment  of essential tremor.

In this randomized, controlled trial involving 76 patients with medication-refractory essential tremor, transcranial focused ultrasound thalamotomy significantly reduced hand tremor.

In conclusion, this study showed that MRI-guided focused ultrasound thalamotomy reduced hand tremor and improved the quality of life in patients with essential tremor. Side effects included sensory and gait disturbances.
