Cortical motor regions are considered to play a role in action related language. These regions are affected differently in different types of movement disorders. Parkinson's disease, a hypokinetic movement disorder, has been shown to cause action language disruptions alongside movement deficits. Action language, however, has not been investigated in primary cervical dystonia, a hyperkinetic movement disorder. The aim of this study is to investigate whether action language is affected differently in hypokinetic and hyperkinetic movement disorders which have different effects on movements. Thirty patients with Parkinson's disease, thirty primary cervical dystonia patients and thirty healthy controls were included in the study. Participants performed phonemic, semantic and action fluency tasks. Verbs produced during action fluency were grouped as action and non-action verbs and group differences were investigated. Our results showed that all participants performed similarly in all of the fluency tasks. Mean action content of the verbs produced in action fluency did not differ between groups. During action fluency, however, whereas healthy controls produced more action verbs than non-action verbs, both patient groups did not have this difference between verb groups. Primary cervical dystonia patients produced less action verbs compared to healthy controls. The lack of action language deficits in Parkinson's disease and only an action verb deficit in primary cervical dystonia without any other action language deficits reject strong embodiment.
皮质运动区被认为在与动作相关的语言中起作用。这些区域在不同类型的运动障碍中受到的影响不同。帕金森病是一种运动减少的运动障碍，已被证明会导致运动缺陷和动作语言障碍。然而，原发性颈肌张力障碍，一种运动过度的运动障碍，其动作语言尚未得到研究。本研究旨在探讨动作语言在运动障碍中的作用是否不同，因为运动障碍对运动的影响不同。研究纳入了 30 名帕金森病患者、30 名原发性颈肌张力障碍患者和 30 名健康对照者。参与者进行了语音、语义和动作流畅性任务。将动作流畅性中产生的动词分为动作动词和非动作动词，并对组间差异进行了研究。我们的结果表明，所有参与者在所有流畅性任务中的表现相似。动作流畅性中产生的动词的平均动作内容在组间没有差异。然而，在动作流畅性中，健康对照组产生的动作动词多于非动作动词，而两组患者在动词组之间没有这种差异。原发性颈肌张力障碍患者产生的动作动词少于健康对照组。帕金森病患者没有动作语言缺陷，只有原发性颈肌张力障碍患者有动作动词缺陷，而没有其他动作语言缺陷，这否定了强烈的具身性。
