BACKGROUND
Gilles de la Tourette syndrome (GTS) is a neuropsychiatric disorder defined by motor and phonic tics. Sensory stimuli can trigger tics, which suggests that GTS is a disorder of perception-action processing rather than a pure motor disorder.
CASE REPORT
We describe a GTS patient that developed exacerbation of tics after transcutaneous electro-myo-stimulation (YGTSS pre-EMS 27/100, post-EMS 69/100).
DISCUSSION
If behaviorally irrelevant stimuli exacerbate tics, there might be a high readiness of the motor system to respond to any stimulus in these patients. In addition to tighter binding between previously established perception-action links, the likelihood for the formation of automatic perception-action links might also be higher in GTS.
背景
Gilles de la Tourette 综合征（GTS）是一种神经精神障碍，其特征为运动性和发音性抽搐。感觉刺激可引发抽搐，这表明 GTS 是一种感知-动作加工障碍，而不仅仅是纯粹的运动障碍。
病例报告
我们描述了一例 GTS 患者，在接受经皮肌电刺激（YGTSS 治疗前为 27/100，治疗后为 69/100）后，抽搐加剧。
讨论
如果行为上无关的刺激会加重抽搐，那么这些患者的运动系统可能更容易对任何刺激做出反应。除了之前建立的感知-动作联系之间的绑定更紧密之外，在 GTS 中，自动感知-动作联系的形成可能性也可能更高。
