Geste antagonistes, or sensory tricks, are well described in focal dystonia affecting the neck, hand, and face. Improvement in dystonic movements is typically maintained while the trick is performed, but disappears when the geste ends. We investigated the phenomenological features of geste antagoniste maneuvers in 19 patients with idiopathic lower cranial dystonia who were prospectively evaluated over a period of 6 years. Of the 19, 10 were men, mean age of onset was 49.8 years, and the most commonly involved lower cranial area was the jaw (10 patients). In most patients, dystonia was task-specific. Taking advantage of the improvement with a sensory geste, we manufactured oral appliances that mimicked the geste in 8 patients, and 3 continue to use it.
对抗性姿势，即感觉技巧，在影响颈部、手部和面部的局灶性肌张力障碍中已有充分描述。在进行该技巧动作时，肌张力障碍性动作通常会得到改善，但当动作结束时就会消失。我们对19例特发性下颅肌张力障碍患者进行了前瞻性评估，为期6年，研究了对抗性姿势动作的现象学特征。19例患者中，10例为男性，平均发病年龄为49.8岁，下颅最常受累的部位是下颌（10例患者）。在大多数患者中，肌张力障碍是特定任务相关的。利用感觉动作带来的改善，我们为8例患者制作了模仿该动作的口腔矫治器，其中3例仍在使用。
