I am a doctor. In fact, I am a neurologist (IAAN). This article is fascinating, and I hope they keep working on this technology and get it working. That being said, I would never plug one of these things into my own amputated limb. Going to medical school and doing residency have turned me into something of a Luddite. Medical technology is cool, but every treatment has potential benefits and toxicities. The adverse event I would worry about most with this technology is neuropathic pain. Neuropathic pain is notoriously difficult to treat. What if you plugged this device into some amputee's limb and gave them excruciating pain? I would rather have a metal hook for a hand.
