The body ownership illusion (BOI) is associated with multisensory integration, including visuo tactile, visuo- proprioceptive, tactile-proprioceptive, visual-interoceptive integration and so forth. BOI can be modulated by various factors like the perceived body/limb size, transparency of the body/limb and so on. A series of studies have demonstrated that BOI may be able to reduce acute and chronic pain. Altered body representation represents one of the mechanisms associated with the analgesic impact of BOI, which involves the integrations between the “body matrix” and the “pain matrix”. Moreover, the posterior parietal cortex (PPC) may play a key role in these integrations, which needs to be further validated in fine-designed protocols. Future studies may wish to further characterize the influence of BOI on pain, taking into account the influence of interoception as well as interrogating potential mechanistic evidence, particularly in various chronic pain conditions.

身体拥有感错觉以多通道的感官整合为基础,包括视觉-触觉、视觉-本体感觉、触觉-本体感觉、视觉-内感受的整合等。来自实验室急性痛以及慢性痛的大量结果表明拥有感错觉可产生镇痛作用。身体部位尺寸大小、肢体透明度等相关影响因素也逐渐得到揭示。拥有感错觉影响疼痛的机制与身体表征的改变有关,该过程可能涉及“身体网络”与“疼痛网络”间的连接,其中后顶叶皮层可能有重要作用。未来研究应更为深入地探索拥有感错觉范式以考察不同因素对疼痛的影响;在现有多感官整合的范式中重视内感受的作用;考察拥有感错觉改变疼痛的认知神经机制;区分急、慢性痛条件下以及不同慢性痛类型中拥有感错觉对疼痛的不同影响。
