According to embodied cognition, processing language with motor content involves a simulation of this content by the brain motor system. Patients with brain lesions involving the motor system are characterized by deficits in action verbs processing in the absence of dementia. We sought to assess whether action verbs interfere with the motor behavior of patients with Parkinson's disease (PD) having tremor dominant symptoms. PD tremor is considered to result from dysfunction of cortical-subcortical motor circuits driven by dopamine depletion. In addition, PD tremor is reduced during active movement execution. Therefore, likewise movement execution, the motor simulation of bodily actions predicted by the embodiment may show to be effective in modifying tremor by interfering with a dysfunctional motor system. Here, we asked to simply read and repeat words expressing a hand-related bodily action. Abstract verbs served as control. Changes in tremor kinematics were evaluated using a monoaxial accelerometer. Seventeen PD patients with rest tremor of the upper limbs were enrolled. Tremor amplitude was significantly smaller when reading action verbs as compared to abstract verbs. We provide empirical evidence supporting the embodied cognition theory by showing that circuits mediating tremor of PD patients are distinctively affected by processing action language.

语言在震颤性帕金森氏病患者中的体现。

根据所体现的认知，具有运动内容的语言处理包括大脑运动系统对该内容的模拟。大脑病变涉及运动系统的患者的特征是在没有痴呆症的情况下动作动词处理不足。我们试图评估动作动词是否干扰具有震颤优势症状的帕金森氏病（PD）患者的运动行为。PD震颤被认为是由多巴胺消耗驱动的皮质-皮层下运动电路功能障碍引起的。另外，在主动运动执行过程中，PD震颤得以减少。因此，同样地执行运动，通过实施例预测的身体动作的运动模拟可以显示出通过干扰功能失调的运动系统而有效地改善了震颤。这里，我们要求简单地阅读并重复表达与手相关的身体动作的词语。抽象动词充当控制。使用单轴加速度计评估震颤运动学的变化。入选了17例上肢休息震颤的PD患者。与抽象动词相比，阅读动作动词时的震颤幅度明显较小。我们通过证明介导PD患者震颤的回路受到加工动作语言的显着影响，从而提供了支持体现认知理论的经验证据。与抽象动词相比，阅读动作动词时的震颤幅度明显较小。我们通过证明介导PD患者震颤的回路受到加工动作语言的显着影响，从而提供了支持体现认知理论的经验证据。与抽象动词相比，阅读动作动词时的震颤幅度明显较小。我们通过证明介导PD患者震颤的回路受到加工动作语言的显着影响，从而提供了支持体现认知理论的经验证据。
