Visual–motor illusion (VMI) is to evoke a kinesthetic sensation by viewing images of oneself performing physical exercise while the body is at rest. Previous studies demonstrated that VMI activates the motor association brain areas; however, it is unclear whether VMI immediately alters the resting-state functional connectivity (RSFC). This study is aimed to verify whether the VMI induction changed the RSFC using functional near-infrared spectroscopy (fNIRS). The right hands of 13 healthy adults underwent illusion and observation conditions for 20 min each. Before and after each condition, RSFC was measured using fNIRS. After each condition, degree of kinesthetic illusion and a sense of body ownership measured using the Likert scale. Our results indicated that, compared with the observation condition, the degree of kinesthetic illusion and the sense of body ownership were significantly higher after the illusion condition. Compared with the observation condition, RSFC after the illusion condition significantly increased brain areas associated with kinesthetic illusion, a sense of body ownership, and motor execution. In conclusion, RSFC has become a biomarker that shows changes in brain function occurring due to VMI. VMI may be applied to the treatment of patients with stroke or orthopedic diseases.

视觉运动错觉（VMI）是通过在身体静止时观看自己进行体育锻炼的图像来唤起一种运动感觉。先前的研究表明，VMI可以激活运动联想大脑区域。但是，尚不清楚VMI是否立即更改静止状态功能连接（RSFC）。这项研究旨在通过功能性近红外光谱（fNIRS）验证VMI感应是否改变了RSFC。13名健康成年人的右手进行了幻觉和观察，每次观察20分钟。在每种情况之前和之后，使用fNIRS测量RSFC。在每种情况下，使用李克特量表测量运动觉错觉的程度和身体归属感。我们的结果表明，与观察条件相比，幻觉后，动觉幻觉的程度和身体归属感显着提高。与观察条件相比，错觉条件后的RSFC显着增加了与动觉错觉，身体归属感和运动执行有关的大脑区域。总之，RSFC已成为显示由于VMI引起的脑功能变化的生物标志物。VMI可用于治疗中风或骨科疾病的患者。RSFC已成为显示由于VMI引起的脑功能变化的生物标志物。VMI可用于治疗中风或骨科疾病的患者。RSFC已成为显示由于VMI引起的脑功能变化的生物标志物。VMI可用于治疗中风或骨科疾病的患者。
