近年来，已经形成了一个共识，即上肢神经假体需要提供体感反馈才能有用。一种越来越有前途的感觉恢复方法是电刺激沿着躯体感觉神经轴的神经元，以传达有关假肢状态和与物体接触的信息。沿着躯体感觉神经轴。迄今为止，对人工感觉反馈的努力主要包括证明一些感觉信息可以使用少量的刺激模式来传达，通常通过单个电极传递。无论这些成就多么令人印象深刻，不同研究的结果很难比较，因为每个研究团队都采用不同的刺激模式，并以不同的方式测试所引发的感觉。一个关键的问题是，不同的刺激策略是否会从人为的实验室设置推广到日常生活活动。在这里，我们列出了人工体感通道应该满足的一些关键规范，讨论了应该如何评估不同的方法，并对感觉恢复领域即将面临的挑战提出了警告。
In recent years, a consensus has emerged that somatosensory feedback needs to be provided for upper limb neuroprostheses to be useful. An increasingly promising approach to sensory restoration is to electrically stimulate neurons along the somatosensory neuraxis to convey information about the state of the prosthetic limb and about contact with objects. To date, efforts toward artificial sensory feedback have consisted mainly of demonstrating that some sensory information could be conveyed using a small number of stimulation patterns, generally delivered through single electrodes. However impressive these achievements are, results from different studies are hard to compare, as each research team implements different stimulation patterns and tests the elicited sensations differently. A critical question is whether different stimulation strategies will generalize from contrived laboratory settings to activities of daily living. Here, we lay out some key specifications that an artificial somatosensory channel should meet, discuss how different approaches should be evaluated, and caution about looming challenges that the field of sensory restoration will face.
