BACKGROUND
Volitional control of involuntary movements has so far been considered a hallmark of tic disorders. However, modulation of involuntary movements can also be observed in other hyperkinesias.
CASES
Here, we present 6 patients with chorea able to suppress their involuntary movements, on demand. In 3 of them, surface electromyography was used to quantify degree of suppression and confirmed a reduction of muscle activity up to 68%, during volitional control.
CONCLUSION
This observation represents a first step toward a description of a new clinical feature in choreic syndromes and an opportunity to redefine the role of volitional inhibition in hyperkinetic movement disorders.
背景
迄今为止，非自主运动的意志控制一直被视为抽动障碍的一个标志。然而，在其他运动亢进中也可观察到非自主运动的调节。
病例
在此，我们报告6例舞蹈症患者能够按需抑制其非自主运动。其中3例患者使用表面肌电图来量化抑制程度，并证实了在意志控制期间肌肉活动减少高达68%。
结论
这一观察结果是描述舞蹈症综合征新临床特征的第一步，也是重新定义意志抑制在运动亢进性运动障碍中作用的一个契机。
