Abstract
Background and purpose: Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration.
Methods: A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM).
Results: Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months (p=0.031 and 0.011, respectively). However, subscore C did not change significantly from baseline when assessed at 2 and 3 months (p=0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group (p>0.001).
Conclusions: Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups.
期刊介绍：
The JCN aims to publish the cutting-edge research from around the world. The JCN covers clinical and translational research for physicians and researchers in the field of neurology. Encompassing the entire neurological diseases, our main focus is on the common disorders including stroke, epilepsy, Parkinson''s disease, dementia, multiple sclerosis, headache, and peripheral neuropathy. Any authors affiliated with an accredited biomedical institution may submit manuscripts of original articles, review articles, and letters to the editor. The JCN will allow clinical neurologists to enrich their knowledge of patient management, education, and clinical or experimental research, and hence their professionalism.
