Motor imagery is a mental process not accompanied by movement and widely studied in healthy subjects, related to hand movements in terms of timing. This study compared static and dynamic motor imagery analyzing temporal and spatial features in different locomotor conditions in three different groups of subjects: high-skilled athletes with visual impairments, a group of sighted unprofessional athletes and a control group of sighted subjects. We found that dynamic motor imagery resulted in timely closer to real performance than static motor imagery. The discrepancies between dynamic motor imagery and real condition, in fact, resulted limited to uncommon locomotion, such as lateral walking. Motor imagery resulted closer to real performance in terms of timing than in terms of step length, with the exception of athletes with visual impairments that, differently from the other groups, did not show any significant differences between the numbers of imagined and performed steps. It opens a new question about the relationship between temporal and spatial imagination of locomotion.

运动图像是一种不伴随运动的心理过程，在健康受试者中得到了广泛的研究，与计时方面的手部运动有关。这项研究比较了静态和动态运动图像，分析了三组不同对象在不同运动条件下的时空特征：具有视觉障碍的高技能运动员，有视力的非专业运动员和有视力的对照组。我们发现动态动态影像比静态动态影像更及时地接近真实性能。实际上，动态运动图像与实际状况之间的差异仅限于不常见的运动，例如横向行走。运动影像在计时方面比在步长方面更接近真实表现，但视力障碍的运动员除外，与其他组不同，在想象的步骤和执行的步骤之间没有显示任何显着差异。这为运动的时空想象与空间想象之间的关系提出了一个新的问题。
