We present the case of a female patient who developed complex regional pain syndrome (CRPS) after a right-foot injury. The patient had pain from the right knee to the toes and showed severe disgust at the appearance of the affected limb. Consequently, the affected limb was not fully loaded, and the patient had difficulty walking. General interventions, such as mirror therapy, were attempted, but the effect was limited. We hypothesized that this was due to the disgust toward the affected limb, and we implemented a body-shadow intervention that we developed. This reduced the disgust for the affected limb and improved pain, but neither changed the anticipated pain of loading the affected limb nor improved the patient’s walking ability. The reason for this was considered to be that the previous interventions using the body shadow utilized the third-person perspective, denoting that the image of the load sensation on the sole of the foot during walking was insufficient; therefore, we attempted a first-person body-shadow intervention. The results showed improvement in the patient’s walking ability. In CRPS of the foot, it is important to use interventions that evoke images of loading without causing anticipatory pain, pointing to the effectiveness of body-shadow interventions.

使用身体阴影干预脚部复杂区域疼痛综合征患者的负荷影像的干预：一例报告

我们介绍了一名女性患者的案例，该患者在右脚受伤后发展为复杂的局部疼痛综合征（CRPS）。该患者从右膝盖到脚趾疼痛，并在患肢外观上表现出严重的厌恶感。因此，患肢未完全负荷，患者难以行走。尝试了一般的干预措施，例如镜子疗法，但效果有限。我们假设这是由于对患肢的厌恶，我们实施了我们开发的身体阴影干预措施。这减少了对患肢的厌恶并改善了疼痛，但是既没有改变预期的负荷患肢的疼痛，也没有改善患者的步行能力。认为其原因是先前使用人体阴影进行的干预使用了第三人称视角，这表明步行过程中脚底的负荷感的图像不足。因此，我们尝试进行第一人称身体阴影干预。结果显示患者的步行能力得到改善。在脚的CRPS中，重要的是要使用能够唤起负荷图像而又不会引起预期疼痛的干预措施，从而指出人体阴影干预措施的有效性。
