We report a 25-year-old woman with an unusual complex psychogenic movement disorders consisting of blepharospasm, tremor, and myoclonus. The tremor appeared in both arms and legs with resting, kinetic, and postural tremor of a variable amplitude, direction, and frequency. The analysis of the arm tremor with surface electromyogram revealed that it consisted of reciprocal and alternating contraction of the wrist flexor and extensor. No apparent co-activation of agonist-antagonist muscles could be seen at the onset of the tremor at rest or at its appearance while performing diadochokinesis.
我们报告了一名25岁女性，患有由眼睑痉挛、震颤和肌阵挛组成的罕见复杂心因性运动障碍。震颤出现在双臂和双腿，表现为静息性、运动性和姿势性震颤，幅度、方向和频率各异。通过表面肌电图对臂部震颤进行分析发现，它由腕部屈肌和伸肌的交替收缩组成。在静息震颤发作时或在进行轮替动作时震颤出现时，未观察到明显的主动肌-拮抗肌共同激活。
