Our interaction with the world rests on the knowledge that we are a body in space and time, which can interact with the environment. This awareness is usually referred to as sense of embodiment. For the good part of the past 30 years, the rubber hand illusion (RHI) has been a prime tool to study embodiment in healthy and people with a variety of clinical conditions. In this paper, we provide a critical overview of this research with a focus on the RHI paradigm as a tool to study prothesis embodiment in individuals with amputation. The RHI relies on well-documented multisensory integration mechanisms based on sensory precision, where parietal areas are involved in resolving the visuo-tactile conflict, and premotor areas in updating the conscious bodily representation. This mechanism may be transferable to prosthesis ownership in amputees. We discuss how these results might transfer to technological development of sensorised prostheses, which in turn might progress the acceptability by users.
我们与世界的互动基于这样一种认知，即我们是处于时空之中的一个身体，能够与环境进行互动。这种意识通常被称为身体感知。在过去30年的大部分时间里，橡皮手错觉（RHI）一直是研究健康人群和患有各种临床疾病人群身体感知的主要工具。在本文中，我们对这项研究进行了批判性综述，重点关注RHI范式作为研究截肢个体假体身体感知的工具。RHI依赖于基于感官精度的、有充分记录的多感官整合机制，其中顶叶区域参与解决视觉-触觉冲突，而运动前区则参与更新有意识的身体表征。这种机制可能适用于截肢者对假肢的所有权认知。我们讨论了这些结果如何可能转化为有传感器的假肢的技术发展，而这反过来又可能提高用户的接受度。
