运动想象（MI）是在没有明显运动输出的情况下对运动的心理模拟，已被证明是一种支持帕金森病（PD）等神经系统疾病运动康复的技术。现有证据表明，MI在PD中很大程度上得以保留，但既往研究通常检查了MI的总体指标，并未考虑症状表现的个体差异对MI的潜在影响。本研究调查了44名轻度至中度特发性PD患者的整体运动症状、运动迟缓和震颤严重程度对MI生动性评分的影响。线性混合效应模型显示，图像方式和左侧运动迟缓的严重程度显着影响MI生动的评级。与先前的研究结果一致，参与者认为视觉运动想象（VMI）比动觉运动想象（KMI）更生动。左侧运动迟缓（而不是右侧运动迟缓）的严重程度越高，KMI的生动性越高，而震颤严重程度和总体运动症状严重程度并不能预测MI的生动性。运动迟缓对左侧的影响的特异性可能反映了优势（右侧）侧更大的病前生动性，或者对身体左侧更费力的运动的注意力增加，从而产生更生动的运动想象。
Motor imagery (MI), the mental simulation of movement in the absence of overt motor output, has demonstrated potential as a technique to support rehabilitation of movement in neurological conditions such as Parkinson's disease (PD). Existing evidence suggests that MI is largely preserved in PD, but previous studies have typically examined global measures of MI and have not considered the potential impact of individual differences in symptom presentation on MI. The present study investigated the influence of severity of overall motor symptoms, bradykinesia and tremor on MI vividness scores in 44 individuals with mild to moderate idiopathic PD. Linear mixed effects modelling revealed that imagery modality and the severity of left side bradykinesia significantly influenced MI vividness ratings. Consistent with previous findings, participants rated visual motor imagery (VMI) to be more vivid than kinesthetic motor imagery (KMI). Greater severity of left side bradykinesia (but not right side bradykinesia) predicted increased vividness of KMI, while tremor severity and overall motor symptom severity did not predict vividness of MI. The specificity of the effect of bradykinesia to the left side may reflect greater premorbid vividness for the dominant (right) side or increased attention to more effortful movements on the left side of the body resulting in more vivid motor imagery.
