Method:
We randomly assigned, in a 2:1 ratio, patients with markedly asymmetric Parkinson’s disease who had motor signs not fully controlled by medication or who were ineligible for deep-brain stimulation surgery to undergo focused ultrasound subthalamotomy on the side opposite their main motor signs or a sham procedure.

Findings:
This randomized, sham-controlled trial showed that focused ultrasound subthalamotomy performed in one hemisphere improved the motor features of Parkinson’s disease on the more affected side at 4 months.
