CONCLUSION
tremor
Our findings suggest that 1‐Hz cerebellar rTMS is a relatively safe and potentially effective noninvasive treatment technique for ET patients that can reduce the amplitude of tremor and improve the patient's specific motor tasks. Meanwhile, because of its advantages of convenience, effectiveness, and relatively cheap price, rTMS is easy to be accepted by patients. And the same effect could also be observed in treatment with propranolol. However, we did not find any differences between the two treatments. Future studies should include larger sample sizes of ET patients to explore other stimulation sites and parameter selection for rTMS and exploit more rigorous designs, such as sham stimulation, to address the placebo effect and other limitations.
