Abstract：
(1) To assess the ability to generate both kinesthetic and visual motor imagery in participants with carpal tunnel syndrome (CTS), compared with asymptomatic participants. (2) To assess the influence of psychophysiological and functional variables in the motor imagery process.
Twenty patients with unilateral CTS and 18 pain-free individuals were recruited. An observational case-control study with a nonprobability sample was conducted to assess visual and kinesthetic movement imagery ability and psychophysiological variables in patients with CTS compared with asymptomatic participants in a control group. The trial was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology statement.
CTS patients have more difficulties in generating visual motor images compared with asymptomatic individuals ( t =-2.099; P <0.05; d=0.70). They need more time to complete the mental tasks (visual t =-2.424; P <0.05 and kinesthetic t =-2.200; P <0.05). A negative correlation was found between the ability to imagine and functional deficits ( r =-0.569; P =0.021) for the kinesthetic subscale and temporal summation ( r =-0.515; P <0.5). A positive correlation was found between pain pressure threshold homolateral (homolateral) and time to generate the visual mental images ( r =0.537; P <0.05).
CTS patients have greater difficulty generating motor images than asymptomatic individuals. Patients also spend more time during mental tasks. CTS patients present a relationship between temporal summation and the capacity to generate kinesthetic images. In addition, the CST patients presented a correlation between chronometry mental tasking and mechanical hyperalgesia.

摘要：
目的：1）评估腕管综合征（CTS）参与者产生动觉和视觉运动意象的能力，与无症状参与者相比。2）评估运动想象（MI）过程中心理生理和功能变量的影响。
方法：招募20例单侧CTS患者和18例健康受试者。我们进行了一项非概率样本的观察性病例对照研究,以评估CTS患者与对照组(CG)中无症状参与者相比的视觉和动觉运动想象能力和心理生理变量.该试验是根据加强流行病学观察研究报告（STROBE）声明进行的。
结果：与无症状受试者相比，CTS患者在生成视觉运动图像方面有更多困难（t=-2.099；P<.05；d=0,70）。他们需要更多的时间来完成心理任务(视觉，t=-2.424；P<.05，动觉t=-2.200；P<.05）。想象能力和功能缺陷之间呈负相关（r=-0.569；P=0.021），对于动觉分量表和时间总和（r=-0.515；P=<0.5）。疼痛压力阈值同侧（PPT-同侧）与产生视觉心理图像的时间呈正相关（r=0.537；P<0.05）。
结论：CTS患者产生运动图像的难度更大。患者在心理任务中花费更多的时间。CTS患者表现出时间总和与生成动觉图像的能力之间的关系。此外,CST患者表现出计时精神任务和机械性痛觉过敏之间的相关性。
