One of the most common forms of chronic pain is back pain. Until now nothing is known about the influence of seeing one¿s own back on pain perception at this site. Previously we implemented online video feedback of the back during painful pressure stimuli over the trapezius muscle. Visual feedback of the back reduced perceived pain intensity compared to feedback of the hand in both patients and controls. However, the supraspinal mechanism behind pain reduction induced by seeing one¿s own back is currently unknown. Therefore, we will use functional magnetic resonance imaging (fMRI) to measure brain activation in 20 healthy controls (HC) during painful electrical stimuli of the back while subjects receive visual feedback of a) the dorsum of the hand, b) the site on the back were the stimuli are applied and c) a third persons back. Participants will rate pain intensity during the measurement.

最常见的慢性疼痛之一是背痛。到目前为止，我们还不知道看到自己的背部对这个部位的疼痛感知的影响。此前，我们在斜方肌受到疼痛压力刺激时实现了背部的在线视频反馈。与患者和对照组的手部反馈相比，背部的视觉反馈降低了感知的疼痛强度。然而，通过看到自己的背部引起的疼痛减轻背后的脊髓上机制目前尚不清楚。因此，我们将使用功能磁共振成像 (fMRI) 来测量 20 名健康对照组 (HC) 在背部疼痛性电刺激期间的大脑激活情况，同时受试者接收 a) 手背、b) 背部施加刺激的部位和 c) 第三人背部的视觉反馈。参与者将在测量过程中评估疼痛强度。
