ESSENTIAL TREMOR, MOVEMENT DISORDERS
Essential tremor (ET) is one of the most frequent movement disorders and is defined as 4–12 Hz kinetic or postural tremor mainly involving the bilateral upper region with or without head tremor or tremor in other locations (Bhatia et al., Existing studies indicate that propranolol and primidone remain the preferred oral agents for ET, and propranolol can significantly reduce the amplitude of tremor (Schneider & Deuschl, As the amplitude of the tremor increased, medication treatment became less effective. Surgical approaches often have been used for drug‐refractory ET, mainly consisting of deep brain stimulation and thalamotomy procedures with radiofrequency, gamma knife radiosurgical thalamotomy, and, most recently, focused ultrasound thalamotomy (Dallapiazza et al., However, existing studies did not compare the efficacy of propranolol and rTMS for ET patients. We present a prospective study to further evaluate the efficacy of propranolol (oral medication) compared with cerebellar low‐frequency rTMS in patients with ET. This will help healthcare providers and ET patients select the best treatment.
