Patients with Parkinson disease (PD) are often profoundly slow in their performance of physical tasks, as well as in motor imagery (MI). This may limit the implementation and potential benefits of MI practice during rehabilitation.
The authors investigated whether the quality of MI could be improved by external cueing.
Fourteen patients with PD and 14 healthy controls physically executed and visually imagined a goal-directed aiming task and a box-and-block task, both in the presence and absence of visual and auditory cues. Mental chronometry and eye movement recording allowed objective evaluation of the temporal and spatial characteristics of MI when compared with physical execution. Visual analogue scales were used to assess imagery vividness.
The presence of visual cues significantly reduced the patients' bradykinesia during MI and increased their imagery vividness.
Visual cueing optimizes MI quality for PD patients and is a potential tool to increase the efficacy of MI practice in PD rehabilitation.
帕金森病（PD）患者在进行身体任务和运动想象（MI）时往往非常缓慢。这可能会限制 MI 在康复中的实施和潜在益处。
作者研究了外部提示是否可以改善 MI 的质量。
14 名 PD 患者和 14 名健康对照者在视觉和听觉提示的存在和不存在的情况下，实际执行和视觉想象一个有目标导向的瞄准任务和一个盒子和积木任务。心理计时和眼动记录允许与实际执行相比，对 MI 的时间和空间特征进行客观评估。视觉模拟量表用于评估想象的生动度。
视觉提示的存在显著减少了患者在 MI 期间的运动迟缓，并增加了他们的想象生动度。
视觉提示优化了 PD 患者的 MI 质量，是增加 PD 康复中 MI 练习效果的潜在工具。
