The MR–guided focused ultrasound thalamotomy for refractory essential
tremor is perfectly safe and effective.
Figure 2. Improvement in
Tremor, Disability, and Physical Performance.
Among 10 patients,
the tremor improvements were observed , as shown by hand-tremor subscores
(ranging from 0 to 32) derived from the Clinical Rating Scale for Tremor (CRST,
ranging from 0 to 160) (Panel A),Mean total tremor scores (Panel B),and the
disability subsection of the CRST (Panel C). Drawing task of the Physical
Performance Test (Panel D, left-baseline, right-immediately after thalamotomy),
showing the change from having difficulty in putting pen to paper to improved
drawing ability.
