Mental rotation has attracted the interest of cognitive research on dystonia, but at the moment, contrasting data are available on whether this complex cognitive ability is impaired in the disorder. Here, we assessed spatial and egocentric mental rotation in patients with cervical dystonia (CD). Patients with CD and healthy controls were required to perform a letter rotation task (spatial mental rotation) and to judge laterality of front-facing and back-facing human images (egocentric mental rotation). CD patients were selectively impaired on letter rotation, whereas they did not differ from controls when judging laterality of both front-facing and back-facing bodies. These findings support the view according to which neural circuits involved in spatial processing are dysfunctional in CD.
心理旋转吸引了认知研究对肌张力障碍的兴趣，但目前对于这种复杂的认知能力是否在该疾病中受损存在相互矛盾的数据。在这里，我们评估了颈性肌张力障碍（CD）患者的空间和自我中心心理旋转。要求 CD 患者和健康对照组执行字母旋转任务（空间心理旋转），并判断正面和背面的人体图像的左右（自我中心心理旋转）。CD 患者在字母旋转方面存在选择性障碍，而在判断正面和背面身体的左右侧时，他们与对照组没有差异。这些发现支持了这样一种观点，即涉及空间处理的神经回路在 CD 中功能失调。
