BACKGROUND
The diagnosis of dystonia can be clinically challenging due to its heterogeneous presentation; essential tremor (ET) is a more common neurological disorder, but may be mimicked by other movement disorders, including dystonia, leading to misdiagnosis.
PHENOMENOLOGY SHOWN
In three patients with hand tremor, two with prior diagnoses of ET, we present examples of "spooning" of the hands, characterized by wrist flexion and metacarpophalangeal hyperextension.
EDUCATIONAL VALUE
Subtle dystonic features such as "spooning" may be present during the evaluation of patients with tremor and aid in the diagnosis of dystonia.
背景
肌张力障碍的临床表现具有异质性，其诊断在临床上具有挑战性；特发性震颤（ET）是一种更常见的神经系统疾病，但可能被包括肌张力障碍在内的其他运动障碍所模仿，从而导致误诊。
呈现的现象学
在三名手部震颤患者中，两名先前被诊断为ET，我们展示了手部“勺状”的例子，其特征为腕关节屈曲和掌指关节过度伸展。
教育价值
在震颤患者的评估过程中可能会出现诸如“勺状”等细微的肌张力障碍特征，有助于肌张力障碍的诊断。
