Orthostatic tremor is characterized by tremor of the trunk and legs while standing. Rapid frequency has been emphasized as an important criterion for the diagnosis of this tremor. We observed five patients who had the typical findings of orthostatic tremor but had a wide range of frequencies. All five also had postural hand tremor and a family history of essential tremor, suggesting a relationship between orthostatic tremor and essential tremor. This report also emphasizes the association of orthostatic tremor with painful cramps and a relatively consistent improvement with clonazepam.
直立性震颤的特征是站立时躯干和腿部震颤。快速频率一直被强调为诊断这种震颤的重要标准。我们观察了5例具有直立性震颤典型表现但频率范围较宽的患者。所有5例患者还伴有姿势性手部震颤和特发性震颤家族史，提示直立性震颤与特发性震颤之间存在关联。本报告还强调了直立性震颤与疼痛性痉挛的关联以及使用氯硝西泮后相对一致的改善情况。
