The study aimed to clarify whether the vividness of motor imagery is related to lower limb function and walking ability in patients with hemiplegic stroke.
The study was a cross-sectional preliminary study. The subjects were 15 patients with hemiplegic stroke. The vividness of motor imagery was assessed using the kinesthetic and visual imagery questionnaire. The kinesthetic imagery (KI) involves the sensation of one's own movement, whereas the visual imagery (VI) involves the imagination of a third-person performing the self-movement. Their physical functions were assessed using the Brunnstrom recovery stage, stroke impairment assessment set, 10-m maximum walking speed test, and functional independence measure. KI and VI were compared using the t test. Correlation analysis was performed between KI or VI and various variables as well as between the motor imagery gap (difference between KI and VI) and various variables.
KI was significantly lower than VI (p < .01). KI was correlated not only with lower limb function (r = 0.68) but also with walking speed (r = -0.64). The motor imagery gap was correlated with hip joint function (r = -0.53).
KI and motor imagery gap were associated with lower limb function and walking ability.
本研究旨在阐明运动想象的生动程度是否与偏瘫性脑卒中患者的下肢功能及步行能力相关。
本研究为横断面初步研究。研究对象为15例偏瘫性脑卒中患者。采用动觉和视觉想象问卷评估运动想象的生动程度。动觉想象（KI）涉及自身运动的感觉，而视觉想象（VI）涉及对第三人执行自我运动的想象。采用Brunnstrom恢复阶段、脑卒中损伤评估量表、10米最大步行速度测试和功能独立性测量来评估他们的身体功能。使用t检验比较KI和VI。对KI或VI与各种变量之间以及运动想象差距（KI与VI之间的差异）与各种变量之间进行相关性分析。
KI显著低于VI（p < 0.01）。KI不仅与下肢功能相关（r = 0.68），还与步行速度相关（r = -0.64）。运动想象差距与髋关节功能相关（r = -0.53）。
KI和运动想象差距与下肢功能及步行能力相关。
