摘要
导言 运动想象(MI)是指在不实际做动作的情况下,在头脑中再现动作。运动想象对运动表现、运动学习和神经可塑性有积极影响。我们分析了肌张力障碍(一种复杂的感觉运动障碍)患者的运动想象与运动执行改变之间的联系。我们的研究旨在对功能性肌张力障碍(FD)患者的运动想象能力与器质性肌张力障碍(OD)患者的运动想象能力进行比较。评估包括特定问卷以及标准化的运动、认知和精神量表。结果与OD患者相比,FD患者在KVIQ-20检查的整体视觉和运动感觉量表上的得分都较低(分别为63.1 ± 18.5 vs. 73.7 ± 13.2和54.9 ± 21.9 vs. 68.8 ± 18.2)。FD患者在不同的身体部位也表现出视觉和/或运动神经元损伤。FD和OD患者在想象动作时都更倾向于内部视角。改善肌张力障碍的技术可能在肌张力障碍康复中发挥潜在作用。
Motor imagery ability in patients with functional dystonia
Introduction
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).
Methods
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.
Results
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.
Conclusion
FD patients showed global dysfunction of visual and kinaesthetic MI abilities. Techniques for MI improvements might have a potential role in dystonia rehabilitation.
期刊介绍:
The Journal of Psychosomatic Research is a multidisciplinary research journal covering all aspects of the relationships between psychology and medicine. The scope is broad and ranges from basic human biological and psychological research to evaluations of treatment and services. Papers will normally be concerned with illness or patients rather than studies of healthy populations. Studies concerning special populations, such as the elderly and children and adolescents, are welcome. In addition to peer-reviewed original papers, the journal publishes editorials, reviews, and other papers related to the journal''s aims.
