Orthostatic tremor (OT) is a neurological disease of unknown aetiology. It is defined by the presence of a 10-20 Hz tremor in the legs while standing still. Symptoms described are dizziness and instability that diminish if the patient sits down or leans on something; drinking small amounts of alcohol significantly reduces OT. Due to the dizziness and/or unsteadiness, these patients are usually referred to the neuro-otology department. We report 4 cases diagnosed with OT. The diagnosis of OT should be considered for patients with instability. The clinical history is a key factor to suspect this entity, and the diagnosis is given by the register of 10-20 Hz contractions on limb electromyography. Treatment for this disease consists of medical treatment; the first option is clonazepam.
直立性震颤（OT）是一种病因不明的神经系统疾病。其定义为静止站立时腿部出现10 - 20赫兹的震颤。所描述的症状包括头晕和站立不稳，患者坐下或倚靠物体时这些症状会减轻；少量饮酒可显著减轻直立性震颤。由于头晕和/或步态不稳，这些患者通常会被转诊至神经耳科学科。我们报告4例被诊断为直立性震颤的病例。对于有站立不稳症状的患者应考虑直立性震颤的诊断。临床病史是怀疑该疾病的关键因素，通过肢体肌电图记录到10 - 20赫兹的收缩来做出诊断。这种疾病的治疗包括药物治疗；首选药物是氯硝西泮。
