一位下腿截肢的男子能用思想精确控制他安装的义肢，原因是他截肢过程中保留下的感觉神经被改道连接到大腿，然后大脑可以利用它们与智能义肢进行通信。这位男子可以轻松自如的在平地步行和爬楼梯之间转变，甚至还能踢足球。而在传统截肢中，感觉神经被严重破坏失去了功能。2006年，芝加哥康复中心的Todd Kuiken和同事意识到，在截肢过程中小心的将感觉神经改道，可以保留部分功能，然后可以利用改道的神经信号控制智能义肢。Kuiken团队现在首次将这项技术应用于截肢者。结果显示，只使用机械传感数据智能义肢正确移动的成功率为87%。加入来自神经的数据后，成功率提高到了98%，没有发生严重错误。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
