The sense of prosthesis embodiment, or the feeling that the device has been incorporated into a user's body image, may be enhanced by emerging technology such as invasive electrical stimulation for sensory feedback. In turn, prosthesis embodiment may be linked to increased prosthesis use and improved functional outcomes. We describe the development of a tool to assay artificial hand embodiment in a quantitative way in people with intact limbs, and characterize its operation. The system delivers temporally coordinated visual and tactile stimuli at a programmable latency while recording limb temperature. When programmed to deliver visual and tactile stimuli synchronously, recorded latency between the two was 33 ± 24 ms in the final pilot subject. This system enables standardized assays of the conditions necessary for prosthesis embodiment.
假体融入感，即感觉该装置已融入使用者身体形象的感觉，可能会通过诸如用于感觉反馈的侵入性电刺激等新兴技术得到增强。反过来，假体融入感可能与增加假体使用和改善功能结果相关联。我们描述了一种工具的开发，该工具用于以定量方式测定肢体健全者的人工手融入感，并对其操作进行了表征。该系统在记录肢体温度的同时，以可编程的延迟提供时间协调的视觉和触觉刺激。当编程为同步提供视觉和触觉刺激时，在最后一名试点受试者中，两者之间记录的延迟为33±24毫秒。该系统能够对假体融入所需的条件进行标准化测定。
