背景视觉诱导止痛这个术语描述的是通过观察疼痛的身体部位而不是观察中性物体而产生的一种减少的痛觉。在慢性背痛患者中，实验性疼痛、运动诱发疼痛和习惯性疼痛可以通过视觉反馈来减少。视觉反馈还可以增强推拿治疗和手法治疗的效果。体感注意过程的影响尚不清楚。方法在目前的研究中，参与者在接受拇指和背部疼痛电刺激的同时，看到了他们拇指或背部的实时视频(因素反馈)。此外，使用奇怪的范式，他们必须计算背部或拇指上应用的异常刺激的数量(注意力因素)，并对疼痛强度进行评级。结果我们发现，注意力对注意力有显著的主要影响，并降低了注意力期间的疼痛评级。视觉反馈没有主效应，视觉反馈与注意之间没有显著的交互作用。实验后测试显示，在背部/拇指的视觉反馈和背部/拇指的计数过程中，疼痛强度等级最低。结论这些数据表明，视觉诱导的镇痛对感知的急性疼痛的调制可能受到同时的体感注意任务的影响。我们发现，视觉反馈与体感注意之间的复杂交互作用没有显著的视觉反馈效应。
BackgroundThe term ‘visually induced analgesia’ describes a reduced pain perception induced by watching the painful body part as opposed to watching a neutral object. In chronic back pain patients, experimental pain, movement‐induced pain and habitual pain can be reduced with visual feedback. Visual feedback can also enhance the effects of both massage treatment and manual therapy. The impact of somatosensory attentional processes remains unclear.MethodsIn the current study, participants received painful electrical stimuli to their thumb and back while being presented with either a real‐time video of their thumb or back (factor feedback). In addition, using an oddball paradigm, they had to count the number of deviant stimuli, applied to either their back or thumb (factor attention) and rate the pain intensity.ResultsWe found a significant main effect for attention with decreased pain ratings during attention. There was no main effect for visual feedback and no significant interaction between visual feedback and attention. Post‐hoc tests revealed that the lowest pain intensity ratings were achieved during visual feedback of the back/ thumb and counting at the back/ thumb.ConclusionThese data suggest that the modulation of perceived acute pain by visually induced analgesia may be influenced by a simultaneous somatosensory attention task.SignificanceSomatosensory attention reduced experimental pain intensity in the thumb and back in the presence of both congruent and incongruent visual feedback. We found no significant visual feedback effect on the complex interplay between visual feedback and somatosensory attention.
