Thought-Controlled Prosthetics

Robotics 88

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."

nerve signals / muscle signals (3, Interesting)

xristo70 (1184699) | more than 6 years ago | (#21322321)

Obviously I'm not a neurosurgeon. I look forward to posts from the experts.

But what is the difference between the electrical signals from the nerves and those given off by contracting muscles? Since the nerves which carry the signals are known, why can't those nerve signals be read straight away? Is it a case of much easier signal patterns to identify with the electrical signals of muscles or just a question of signal strength or something much more complicated?

Interesting as well that they should say that when the muscles are touched, for the patient is seems like the prosthetic arm is touched. Too bad they don't mention the perceived sensitivity to temperature and pressure with this effect. Put sensors on the tip of the hand and a little device on his chest and you might give the patient movement and "feeling" as well.

Re:nerve signals / muscle signals (4, Interesting)

WarlockD (623872) | more than 6 years ago | (#21322423)

From what I understand, the communication with nerves not only have to be bi-directional but also we arn't sure what other signals are sent (chemical, etc). We can detect the messages to muscles as those are VERY simple and only require small electrical detectors. Decoding a straight nerve seems still seems beyond our reach.

Mind you, this is much better than before. Previous robotic arms are built this same way, but it takes months and months of training to use your chest muscles to move your arm. Now it looks like you don't need that much therapy since they rout your arm nerves to your chest.

PS - I am no expert, I just looked into it a bit ago when I met someone with a claw hand.

Re:nerve signals / muscle signals (4, Informative)

Alrua (704865) | more than 6 years ago | (#21322615)

There is some research being done into bidirectional prosthetics. Kevin Warwick from Reading University in the UK has successfully implanted a chip in his own arm allowing him to control an external robotic arm and receive sensory input from it.

Some of Warwick's work is pretty controversial (see e.g. various articles from The Register [theregister.co.uk] ), but he does do some solid research.

Re:nerve signals / muscle signals (1)

DavidTurner (614097) | more than 6 years ago | (#21325025)

To clarify, figuring out how the nerves convey messages to the muscles (and ignoring other means of communication as the parent pointed out) is kind of like sticking a bunch of oscilloscope probes onto a moderately complex breadboard and figuring out how it works from what we see on the scopes. 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.

So what we really need is some sort of adaptive machine that figures out how to talk to the brain and then translates into signals conventional circuits can understand. Way beyond what is presently possible.

Re:nerve signals / muscle signals (3, Interesting)

cortex (168860) | more than 6 years ago | (#21323487)

The signals in the nerve can be detected directly, but the are very small, and it is harder to get a micro-electrode array in the nerve. The muscle acts like a bio-amplifier, so that the small impulses from the nerve are measured as larger electro-myographic signals (EMG). I am a neural engineer on f the team at the Univ. of Utah that is working on using the signals in the nerve directly. We can already decode the movement signals from the nerve directly and are investigating how to provide sensory feedback. We have been discussing with Todd Kuiken using our array to map out the sensory and motor fibers in the nerve prior to his surgery, so that he can achieve better separation of the signals. That is, he'll know which nerve fibers carry which signals prior to implanting them on the muscle. We and other universities (Caltech, Brown, U. Pitt...) are also looking into using signals straight from the cerebral cortex to control prosthetic limbs.

Re:nerve signals / muscle signals (1)

jellie (949898) | more than 6 years ago | (#21324745)

I'm not quite sure, but I think that electrical signals from the nerves are much more difficult to record due to the size of the nerves. An EMG, for example, is relatively easy if you stick an electrode into any part of the target muscle.

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 [wikipedia.org] and here [sfn.org] , 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.

Muscle vs Nerve signals (3, Informative)

spineboy (22918) | more than 6 years ago | (#21326187)

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.

Actually, thats an even more disturbing thought that robotroops. Medical companies financing a war so they get lots of maimed soldiers to experiment on.

The reason it occured to me, is that the US currently has a bit of a shortage of troops in Iraq, and certainly faces one going into Iran. Getting an arm or leg blown off is currently a permanant ticket home.

Or, let's get blunt here, how about manufacturers of military hardware? They exist for the purpose of maiming and killing soldiers - Sure, soldiers on the "other" side (as though that magically excuses atrocities against humanity) but still for the purpose of blowing people up.

I agree, "politics" has nothing to do with it - War and all its trappings has no justification beyond "personal defense".

Been watching too much scifi, fellow geek? :)

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.

Certain brands of sci-fi are fond of this (and others--anybody else remember Kujiranami Hyougo, who did this bit in Rurouni Kenshin?), but in fact it's not gonna happen in real life. A gun for a hand is terribly limiting--all you can do is shoot people with it. A reasonable facsimile of an actual hand is vastly more versatile. Wnat to shoot somebody? Pick up a gun and shoot him. Or pick up a hammer and drive a nail. Or pick up a box and carry it where it needs to be. Why would you want a gun bolted on when you can *have* a gun when you need it--and something else when you dont?

A bit off topic but I was wondering... It would be interesting to see if such a system could be adapted to help people with conditions such as ALS. I thought it was the interface between the muscle and the nerve that was damaged in ALS (seemingly by a prion). It seems reasonable that you could replicate that interface using some of the techniques described in the article (maybe an implant in the muscle that responds to signals patched from the nerves).

I guess it might be better to try to competitively inhibit the prion that's causing all of the trouble in the first place. Anyone know if this is an active area of study - finding matched pairs for disease prions seems like a good extension of the folding at home project. Once you find the matched pair, you can code the sequence required to make it into a vector or just inject it directly in the affected muscle tissue.

Very Dissapointed With Slashdot (1)

Hoi Polloi (522990) | more than 6 years ago | (#21323469)

I'm not seeing the obvious "Thought Controled Artificial Penis" jokes yet. Just think how embarrassing it would be to have something like that activating around your friend's hot mom/wife/sister, at work, in the grocery line...

As long as she cares and he's not around what difference does it make? Tally ho!! Time to soothe them thoughts.

In that case, there is a simple solution to prevent any embarrassing moments ever again... an on\off switch!

This brings to mind another Red Dwarf episode, the one where Kryten gets a prosthetic penis. Unfortunately it gets away from him, setting up the joke "My penis has a mind of its own!"

Feedback (2, Interesting)

RicardoRT (1187937) | more than 6 years ago | (#21323529)

Simple motions of a prosthetic device can be accomplished with this approach, but they will always rely on visual feedback. The problem is that it is too slow for more complicated movements, such as delicately grabbing objects of different stiffnesses. As long as no proprioceptive feedback is given to the brain, electromechanical prosthetics will remain cumbersome.

But they forgot the "cyborg" tag in the article. Read Ray Kurzwiel's "Age of spiritual machines", it's very cool, and talks about the social implications of our technological progress.

For an 80gig drive in my head. Assuming it has overload protection and I can double it later.

Obligitory Red Dwarf Moment (1)

Kryten: Hand, Pickup the ball.

Lister: Hand... Pick Up the Ball.

Kryten: Now try again Mr. Lister you're doing great.

Lister: Hand..... PICK UP THE ..... BALL

(Lister Hits Kryten with his new mechanical arm)

Kryten: Hand, Pick up the Ball, not Hand beat Kryten Senseless.

"Shock the Monkey" might make a handy comeback... Call it the "ShoThMo Model 1". Why, with the things we could create, and append to the body, it might give a new meaning to "bi-onics"...

Once Again, just another step towards "Ghost in the Shell" style of prosthetics.

SpatialVacancy (876127) | more than 6 years ago | (#21332535)

if i am thinking about the breasts of a woman sitting next to me will the arm grab it? If I did everything I thought about I would probably be in jail or worse.

i propose the term Psionics (2, Interesting)

AP31R0N (723649) | more than 6 years ago | (#21334877)

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".
