Thought-Controlled Prosthetics

Ponca City, We Love You writes "Physiatrist Todd A. Kuiken, M.D., Ph.D. has pioneered a technique known as targeted muscle reinnervation (TMR), that allows a prosthetic arm to respond directly to the brain's signals, allowing wearers to open and close their artificial hands and bend and straighten their artificial elbows nearly as naturally as their own arms. Doctors first perform nerve transfer surgery to redirect nerves that go to the amputated arm to the patient's chest muscles. Then when the chest muscle contracts, an electromyogram picks up the electrical signal to move the prosthetic arm. So when the patient thinks 'close hand,"' the hand closes. Now the team wants to see if they can extract more information from the electrical signals produced by the nerves to provide a greater number of hand and arm movements. Theyd have been able to identify unique EMG patterns with 95% accuracy for 16 different elbow, wrist, hand, thumb, and finger movements. 'We've been able to demonstrate remarkable control of artificial limbs and it's an exciting neural machine interface that provides a lot of hope,' says Dr. Kuiken."

      I'm not really sure about the patient "feeling" the arm; there should be a lot in the literature about patients who think they can feel sensation through their implant, but it's often because of the other nerves around the implant or prosthetic, and not the implant itself.

      There is another way to have "thought-controled prosthetics": implant an electrode array directly on the brain and train the user to think of movements. By mapping out the specific brain signals, they can determine which neurons fire when the user wants to move his arm, for example, and then trigger to prosthetic to move in the desired way. It's been shown to work by numerous scientists, such as here and here, among others. They seem to have good success with this method, though I don't know about its long-term efficacy, given that the brain can move.

Bear in mind that the circuit is analogue. And we're not quite sure where the nodes are. And we can't actually see the circuit at all.

      Is the information frequency coded? Pulse coded? Phase coded? Some combination of the above? Who knows.

      My hunch, based on the fragmentary information I've seen, is that nerves code messages in all three ways, AND that the encoding differs from person to person.

      Actually, they already have guys going back into the military with the current prosthetics. There was one guy missing a foot who's even back in combat.

      The way I see it, we're probably not going to be seeing ginchy-keen combat prosthetics like in scifi, your submachinegun hand for example. The person will have a limb that's tough, durable, fit for the civilian world, and can also hold a weapon. Right now, a cyborg would be at a disadvantage versus an intact opponent. We still aren't in Bionic Man territory yet.

      Rather than cyborgs with superhuman performance running around, I think the best hope for amputees will be running around with human-level performance so that the artificial limb becomes almost unnoticed. It senses warmth, pressure, kenesthetic feedback accurately, delicate motion, every bit like the normal limb. Close your eyes and you won't even realize it's a fake.

      For actual combat, I think what we're more likely to see is remotely operated combat bots. Think Predator and SWORDS, extrapolate a few decades into the future. The bots will be smart enough to operate autonomously and only phone home when they find something interesting. For someone who is severely fucked up, like body totally trashed, they may elect for a full-body borging where the brain sits in a can and they're doing whatever they need to do in a full sensory immersion environment. The scifi books that went into this sort of concept were "the ship who x" books. The idea there is that babies with crippled bodies but sound minds had their brains scooped out and put into little roller-units. It looks like a gaggle of wheeled boxes with manipulators rolling around but you're actually looking at a nursery full of young children. When these brains are suitably mature, they're assigned to be captains of starships, capable of controlling all aspects of flight down to the last detail.

      This sort of superscience would have to be decades off. if we can't figure out a way to clone working organs for crippled bodies, this would be the likely alternative option. But whether the human is sitting with his brain in a vat or behind a keyboard and joystick, I think we're going to see a huge, huge push towards unmanned weapons. Anything combat-related is going to be driven by a bot with the manned vehicles pulling up the rear in support. I think Iraq is going to be to combat bot development as WWI was for combat aircraft. In other words, things are going to get weird on us in the coming years.

  28. Muscle vs Nerve signals by spineboy · · Score: 3, Informative

    The nerves in the body are usually buried somewhat deep, and are insulated usually by a layer of fat, and by their insulation(fatty Schwann cells). Since the nerves innervate the muscles, the signal becomes amplified, thus making it much easier to pick up the signal (stronger, and just under the skin, not insulated).

    Another reason is that many different nerve fibers run together in a nerve, especially up in the brachial plexus (shoulder are). If this prosthesis is meant for people who have lost their are high up, then the nerves in this location, are somewhat big (between a pencil and strand of linguinni thickness), and contain many different fibers. There are about 30 different muscles in the forearm/hand, and another 20 in the shoulder and arm (and don't forget all the sensory fibers too). It might be just too hard to pick out usable signals from that mess, If some of the fibers are re-routed to a superficial muscle (chest wall pectoralis major), then it's much easier for the person to choose discrete movements, and have control over the prosthesis.

    I am an orthopaedic surgeon, so I'm just posting this part to squelch any criticism about the facts above.

  32. i propose the term Psionics by AP31R0N · · Score: 2, Interesting

    i propose the term Psionics for mind controlled machines (attached or not). Avionics are electronics for aviation, psionics could be electronics related to the brain. Given that only D&D nerds would know of the word having any other use, we could replace the awkward phrases "mind controlled" and "mind machine interface".
