神经肌肉疾病可能是神经心理学的兴趣，因为它们可能影响基于具身认知理论的表征。先前的研究表明，在1型肌强直性营养不良（DM1）患者中，识别面部情绪的能力受损，以及面部情绪识别与视觉空间能力之间的关联。在这里，我们研究了DM1和DM2患者识别身体姿势表达的情绪的能力及其关系，以及它们与认知表现的关联。方法：DM1患者34例，DM2患者8例，健康对照24例。情绪识别能力通过两项计算机匹配任务（面部和身体）进行评估。使用神经心理学电池测量三领域认知和整体认知。我们使用单变量和调整后的线性回归模型来研究认知和情绪识别表现之间的关系。结果：DM患者（DM1和DM2合并）在情绪面部表情（p = 0.006）和身体姿势（p = 0.004）准确性方面的表现低于健康对照组。在线性回归模型中，DM患者的面部表情准确性与执行功能（p = 0.013）和视觉空间（p < 0.001） z-score相关。身体姿势准确性与视觉空间（p = .001）和记忆（p = .012） z分数相关。对照组之间或认知和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受损也延伸到通过身体姿势传达的情绪。与具身认知理论一致，受身体及其运动影响的人可能以尚未完全理解的方式损害了感觉运动表征。(C) 2020 Elsevier Ltd.版权所有。
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.
