INTRODUCTION Neuromuscular diseases may be of neuropsychological interest insofar as they may affect representations based on embodied cognition theories. Previous studies have shown impaired ability to recognize facial emotions and an association between facial emotion recognition and visuospatial abilities in myotonic dystrophy type 1 (DM1) patients. Here we examined the ability of both DM1 and DM2 patients to recognize emotions expressed by body postures and its relation, and their association with cognitive performance. METHODS Participants included 34 DM1 patients, 8 DM2 patients, and 24 healthy control subjects. Emotional recognition ability was assessed through two computerized matching tasks (face and bodies). A neuropsychological battery was used to measure cognition in three domains and global cognition. We used univariate and adjusted linear regression models to investigate the association between cognition and emotion recognition performance. RESULTS DM patients (combined DM1 and DM2) performed worse on emotional facial expression (p = .006) and body posture (p = .004) accuracy measures than healthy controls. In linear regression models, DM patients' facial expression accuracy was associated with executive function (p = .013) and visuospatial (p < .001) z-scores. Body posture accuracy was associated with visuospatial (p = .001) and memory (p = .012) z-scores. There were no associations among controls or between cognition and reaction time. DISCUSSION These findings suggest that impaired emotional recognition among DM patients is also extended to emotions conveyed by body postures. Consistent with embodied cognition theories, people affected in their body and its movement may have impaired sensorimotor representation in ways that have yet to be fully understood.

识别强直性肌营养不良症(DM)中由面部表情和身体姿势传达的情绪。

简介神经肌肉疾病可能会引起神经心理学的关注,因为它们可能会影响基于具体认知理论的表征。先前的研究表明,强直性营养不良1型(DM1)患者的面部表情识别能力受损,面部表情识别与视觉空间能力之间存在关联。在这里,我们研究了DM1和DM2患者识别身体姿势表达的情绪及其关系的能力,以及他们与认知能力的关系。方法参与者包括34名DM1患者,8名DM2患者和24名健康对照组。通过两个计算机匹配的任务(面部和身体)评估情绪识别能力。神经心理学电池被用于测量三个领域的认知和整体认知。我们使用单变量和调整后的线性回归模型来研究认知与情绪识别性能之间的关联。结果与健康对照组相比,DM患者(DM1和DM2合并)在情绪面部表情(p = .006)和身体姿势(p = .004)准确性方面的表现较差。在线性回归模型中,DM患者的面部表情准确度与执行功能(p = .013)和视觉空间(p <.001)z评分相关。身体姿势的准确度与视觉空间(p = .001)和记忆(p = .012)的z得分相关。对照之间或认知与反应时间之间没有关联。讨论这些发现表明,糖尿病患者的情绪识别能力受损也扩展到了身体姿势所传达的情绪。与具体的认知理论一致,
