Magnetic Resonance-Guided Focused Ultrasound Thalamotomy for Focal Hand Dystonia: A Pilot Study.

ABSTRACT:

Background

The efficacy of magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy for the treatment of focal hand dystonia (FHD) is not well known.

Objective

We aimed to prospectively investigate the efficacy of MRgFUS thalamotomy for the treatment of FHD.

Methods

We performed MRgFUS thalamotomy of the ventro-oral (Vo) nucleus in 10 patients with FHD. We evaluated the scores of the Writer's Cramp Rating Scale (WCRS, 0-30; higher scores indicating greater severity), Tubiana Musician's Dystonia Scale (TMDS, 0-5; lower scores indicating greater severity), and Arm Dystonia Disability Scale (ADDS, 0%-100%; lower scores indicating greater disability) at baseline and 3 and 12 months post-treatment.

Results

WCRS, TMDS, and ADDS scores significantly improved
