Brain Nerve 2022 May;74(5):645-651

Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences.

Drug-refractory essential tremors, especially those in the upper extremities, may benefit from surgical treatment. Currently, three main treatment methods are available: deep brain stimulation (DBS), radiofrequency coagulation (RF), and magnetic resonance -guided focused ultrasound surgery (MRgFUS). DBS is a device-based therapy, and its effects are reversible, whereas RF and FUS create irreversible coagulation lesions. Read More

Vim-Thalamic Deep Brain Stimulation for Cervical Dystonia and Upper-Limb Tremor: Quantification by Markerless-3D Kinematics and Accelerometry.

Tremor Other Hyperkinet Mov (N Y) 2022 10;12. Epub 2022 Mar 10.

Department of Neurology, Northwestern University Feinberg School of Medicine, Chicago, Illinois, US.

Background: Deep Brain Stimulation (DBS) for dystonia is usually targeted to the globus pallidus internus (GPi), though stimulation of the ventral-intermediate nucleus of the thalamus (Vim) can be an effective treatment for phasic components of dystonia including tremor. We report on a patient who developed a syndrome of bilateral upper limb postural and action tremor and progressive cervical dystonia with both phasic and tonic components which were responsive to Vim DBS. We characterize and quantify this effect using markerless-3D-kinematics combined with accelerometry. Read More
