Motor imagery (MI) involves recreating a movement mentally without physically performing the movement itself. MI has a positive impact on motor performance, motor learning and neural plasticity. We analysed the connection between motor imagination and altered movement execution in individuals with dystonia, a complex sensorimotor disorder. The aim of our study was to examine MI ability in patients with functional dystonia (FD) in comparison to organic dystonia (OD).
Our case-control study involved 46 patients, 22 with FD and 24 with OD. The assessment consisted of specific questionnaire and standardized motor, cognitive and psychiatric scales. The KVIQ-20 was used to test MI in each patient.
Patients with FD scored lower on both global visual and kinaesthetic scales of the KVIQ-20 exam compared to patients with OD (63.1 ± 18.5 vs. 73.7 ± 13.2, and 54.9 ± 21.9 vs. 68.8 ± 18.2, respectively). Patients with FD also exhibited visual and/or kinaesthetic MI impairment in different body segments. The internal perspective when imagining movements was preferred in both patients with FD and OD.
FD patients showed global dysfunction of visual and kinaesthetic MI abilities. Techniques for MI improvements might have a potential role in dystonia rehabilitation.
运动想象（MI）涉及在不实际执行运动本身的情况下在心理上再现运动。MI 对运动表现、运动学习和神经可塑性有积极影响。我们分析了运动想象与运动障碍患者运动执行改变之间的联系，运动障碍是一种复杂的感觉运动障碍。我们研究的目的是比较功能性运动障碍（FD）和器质性运动障碍（OD）患者的 MI 能力。
我们的病例对照研究包括 46 名患者，22 名 FD 和 24 名 OD。评估包括特定的问卷和标准化的运动、认知和精神病量表。使用 KVIQ-20 测试每位患者的 MI。
FD 患者在 KVIQ-20 检查的全局视觉和动觉量表上的得分均低于 OD 患者（63.1±18.5 与 73.7±13.2，54.9±21.9 与 68.8±18.2）。FD 患者在不同的身体部位也表现出视觉和/或动觉 MI 损伤。在想象运动时，FD 和 OD 患者都更喜欢内部视角。
FD 患者表现出全局视觉和动觉 MI 能力障碍。MI 改善技术在运动障碍康复中可能具有潜在作用。
