Which one is the superior target? A comparison and pooled analysis between posterior subthalamic area and ventral intermediate nucleus deep brain stimulation for essential tremor.

This study provided level IIIa evidence that PSA-DBS was more effective and safer for ET than VIM-DBS in 12-24 months, although both PSA-DBS and VIM-DBS were effective in suppressing tremor in ET patients. Further prospective large-scale randomized clinical trials are warranted in the future.
