摘要

背景和目的:中风患者通常会经历上肢的严重损伤。针对上肢的康复干预通常只能获得小到中等的收益。了解到身体图式可以在其他上肢疾病中改变,有助于定制康复方法的发展。本研究调查了中风患者是否经历了上肢身体图式的改变。如果是这样,这一知识可能会对运动意象等康复方法产生影响。方法:一项在线进行的观察性研究,包括左/右判断任务,评估反应时间和准确性:(i)左/右方向识别;(ii)左/右肩横向识别;(iii)左/右手侧向识别;(iv)非实体物体的心理旋转。在有和没有中风的个体之间进行比较。在中风人群中根据中风的侧面和疼痛的侧面进行了二次比较。结果:共有895人(其中445人中风)参与。与没有中风的人相比,中风患者完成所有任务所需的时间更长,并且在正确识别肩部(P < 0.001)和手部(P < 0.001)图像的侧面以及非实体物体的方向(P < 0.001)方面准确性较低。此外,在手和肩膀任务中观察到的差异大于方向识别和非体现心理旋转的控制任务。脑卒中患者的左/右判断在脑卒中患病侧和疼痛侧无显著差异。讨论和结论:中风后上肢的左/右判断经常受损,提供了身体图式改变的证据。长期中风患者的身体图式会发生改变,这一认识可能有助于上肢最佳的、被广泛接受的运动意象程序的发展。视频摘要可获得作者的更多见解(参见视频,补充数字内容1,可在:http://links.lww.com/JNPT/A394)。

Body Schema as Assessed by Upper Limb Left/Right Judgment Tasks Is Altered in Stroke: Implications for Motor Imagery Training.

Background and purpose: Individuals with stroke often experience significant impairment of the upper limb. Rehabilitation interventions targeting the upper limb are typically associated with only small to moderate gains. The knowledge that body schema can be altered in other upper limb conditions has contributed to the development of tailored rehabilitation approaches. This study investigated whether individuals with stroke experienced alterations in body schema of the upper limb. If so, this knowledge may have implications for rehabilitation approaches such as motor imagery.

Methods: An observational study performed online consisting of left/right judgment tasks assessed by response time and accuracy of: (i) left/right direction recognition; (ii) left/right shoulder laterality recognition; (iii) left/right hand laterality recognition; (iv) mental rotation of nonembodied objects. Comparisons were made between individuals with and without stroke. Secondary comparisons were made in the stroke population according to side of stroke and side of pain if experienced.

Results: A total of 895 individuals (445 with stroke) participated. Individuals with stroke took longer for all tasks compared to those without stroke, and were less accurate in correctly identifying the laterality of shoulder (P < 0.001) and hand (P < 0.001) images, and the orientation of nonembodied objects (P < 0.001). Moreover, the differences observed in the hand and shoulder tasks were greater than what was observed for the control tasks of directional recognition and nonembodied mental rotation. No significant differences were found between left/right judgments of individuals with stroke according to stroke-affected side or side of pain.

Discussion and conclusions: Left/right judgments of upper limb are frequently impaired after stroke, providing evidence of alterations in body schema. The knowledge that body schemas are altered in individuals with longstanding stroke may assist in the development of optimal, well-accepted motor imagery programs for the upper limb.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A394).

期刊介绍: The Journal of Neurologic Physical Therapy (JNPT) is an indexed resource for dissemination of research-based evidence related to neurologic physical therapy intervention. High standards of quality are maintained through a rigorous, double-blinded, peer-review process and adherence to standards recommended by the International Committee of Medical Journal Editors. With an international editorial board made up of preeminent researchers and clinicians, JNPT publishes articles of global relevance for examination, evaluation, prognosis, intervention, and outcomes for individuals with movement deficits due to neurologic conditions. Through systematic reviews, research articles, case studies, and clinical perspectives, JNPT promotes the integration of evidence into theory, education, research, and practice of neurologic physical therapy, spanning the continuum from pathophysiology to societal participation.
