The aim of this study was to assess Virtual Reality (VR) based visual auditory stimulation can relieve pain. To achieve this, the impact that body surface electrical stimulation has on the body surface potentials and activity in the central nervous system in VR environments were extracted. Twenty‐two adults participated in this study. The body surface potentials and Electroencephalogram frequencies were measured under various conditions: non‐viewing, viewing neutral clips, viewing unpleasant clips, and viewing pleasant clips. The pain index was calculated from the body surface potentials. Participants were asked to complete subjective pain measurement scales. Results showed that the pain index and the relative subjective pain score decreased when presented with unpleasant and pleasant video clips. The incidence of alpha waves declined when presented with unpleasant clips, while the incidence of beta waves increased when presented with unpleasant and pleasant video clips. Inattentiveness to pain due to VR immersion and descending pain inhibition due to awareness of emotional stress after viewing VR clips were considered to have contributed to the decline in the pain index and in relative subjective pain score. This study suggests that it is possible to relieve pain by VR viewing related to unpleasant or pleasant.

在虚拟现实环境中使用体表电刺激评估体感敏感性和脑电图活动

这项研究的目的是评估基于虚拟现实（VR）的视觉听觉刺激可以缓解疼痛。为此，我们提取了在VR环境中体表电刺激对体表电位和中枢神经系统活动的影响。22名成年人参加了这项研究。在各种条件下测量了身体表面的电势和脑电图频率：不观看，观看中性剪辑，观看不愉快的剪辑和观看舒适的剪辑。疼痛指数是根据体表电位算出的。要求参与者完成主观疼痛测量量表。结果显示，当出现不愉快的视频片段时，疼痛指数和相对主观的疼痛评分降低。当出现不愉快的剪辑时，α波的发生率下降，而出现不愉快且令人愉悦的视频剪辑时，β波的发生率增加。在观看VR剪辑后，由于VR浸入导致的对疼痛的疏忽和由于意识到情绪压力而导致的疼痛抑制下降被认为是导致疼痛指数和相对主观疼痛评分下降的原因。这项研究表明，通过观看不愉快或令人愉快的VR可以缓解疼痛。在观看VR剪辑后，由于VR浸入导致的对疼痛的疏忽和由于意识到情绪压力而导致的疼痛抑制下降被认为是导致疼痛指数和相对主观疼痛评分下降的原因。这项研究表明，通过观看不愉快或令人愉快的VR可以缓解疼痛。在观看VR剪辑后，由于VR浸入导致的对疼痛的疏忽和由于意识到情绪压力而导致的疼痛抑制下降被认为是导致疼痛指数和相对主观疼痛评分下降的原因。这项研究表明，通过观看不愉快或令人愉快的VR可以缓解疼痛。
